  • 10 marks for biotechnology and its applications.

Important Tips For Class 12 Biology Preparation:

Biology is a subject with a lot of substance. It is unavoidable and necessitates the study of new concepts and terminologies that must be learned and remembered. A few important tips for the preparation of Biology for class 12 are as follows:

1.Make flash cards with meanings for the new terms you learn every day. These flashcards will make it easier for you to review the various concepts learnt.

  • Write the definitions in your own language as closely as possible without changing the meaning. This will assist you in recalling them much more efficiently and will make your study more fruitful.
  • Take the flashcards wherever you go in order to revise quickly without hampering your daily routine.
  • Follow the instructions in your NCERT textbook and, once you’ve grasped the concept, go over your school notes and test papers.
  • Make sure you’re paying attention in lab sessions and that you’re actually doing the experiments.
  • Take notes, highlight important passages, and summarise the page in the margins if you don’t mind making notes in your book.
  • Take notice of the most frequently asked questions and consider how they should be answered.
  • After you’ve finished your syllabus, go over it again as many times as you can. When you’re done, try out the sample papers in a timed situation.
  • Complete as many mock tests as you can.

Tips for Getting Good Grades During the Examination:

  • Whenever possible, write your descriptive answers in points and include pictorial or graphical illustrations during the exam. It makes your answers look more structured.
  • Look over the entire paper and the questions before answering.
  • Before you begin to write your answer, sketch out a skeleton of it in the margin for long-answer questions.
  • While attempting short questions, be succinct and to the point.

NCERT Solutions For Class 12 Biology:

NCERT solutions are a must when preparing for class 12 board exams. NCERT is considered to be the Bible for CBSE subjects and you are most likely to face questions in your exams which are straight from the textbook. Therefore it is very crucial to practise all the textbook questions and the NCERT solutions will help you in doing so. These solutions are prepared by experts and will provide you with precise answers for all the problems and exercises in your textbook. Some of the major chapters included into these solutions are:

Reproduction in Organisms:

Reproduction in organisms is a chapter that outlines how different organisms reproduce. Reproduction is a vital biological process in which an organism produces an offspring that is genetically identical to itself.

Sexual Reproduction in Flowering Plants

The anatomy, structure, and methods of sexual reproduction in angiosperms are explained in Sexual Reproduction in Flowering Plants. It also goes into detail about subtopics including pre-fertilisation: structure and events, double fertilisation, post-fertilisation: structure and events, apomixis, and polyembryony.

Human Reproduction

The creation of gametes (gametogenesis) in humans, i.e. sperms in males and ovum in females, is one of the most important reproductive events. After reaching a particular age, humans develop sexual maturity, which is referred to as puberty. There are significant distinctions between the male and female reproductive organs. The male and female reproductive systems in humans will be examined in this chapter. The male reproductive system, the female reproductive system, gametogenesis, menstrual cycle, fertilisation and implantation, pregnancy and embryonic development, parturition, and nursing are all addressed in this chapter.

Your Baby

Easy Ways To Bond With Your Baby

So you are now a mommy. Having a child sure does change you. Along with a high emotional upgrade, you must have sensed a shift in your natural instincts. Your hunches are stronger now and you want to bond with your baby to the full extent. After all, your little one and you have spent 9 months of deep connection with each other and you wish to continue being closer than ever with your baby. But, somehow you are finding it extremely difficult to bond with your tiny one. No matter how much you try you just seem to always be concerned about how you are unable to bond with your kid.

The lack of bonding can be due to various reasons such as exhaustion from a long labor and delivery, or simply feeling overwhelmed by the heavy responsibility of motherhood. Even if you did not have the opportunity to enjoy physical closeness with your baby immediately after birth for whatever reason, there is still plenty of time for you to establish a close connection with your child. Read on for 5 easy ways to bond with your baby after birth:

Eye Contact Establishment

Newborn babies can see objects at breastfeeding distance. When feeding your baby, be sure to maintain eye contact and you will be able to communicate your love to him or her.

The Magic of Touch

Your touch is very reassuring to your baby. Massaging your baby daily is a wonderful way to bond with your child. It is important to use good quality massage oil that is suitable for infants such as olive oil, sweet almond or sunflower oil, and when massaging, make sure that your hands are open and relaxed. To learn more about infant massage techniques, you can take a class on it or read a book on the topic.

You can also bond with your baby during bath time and enjoy the skin contact as you wash him or her. After bathing and patting your baby dry, you can also communicate your love by massaging your little one with a mild moisturising lotion to prevent skin dryness.

Talk to Your Baby

Your baby can recognise the sound of your voice and hearing your voice gives your child a sense of security. Talk to your baby whenever you can such as during bath time, nappy changes, or even when you leave the room.

You can also read aloud to your baby regularly — this is not only a great bonding opportunity, but also stimulates your child’s language development. You can also communicate with your child through music. Singing must not be restricted to bed time only. Other than singing lullabies, you can sing soft tunes any time of the day. Doing so has been proven to be very effective in the development of a child’s psychology as music seems to have a loving and positive effect. Also, it may influence your child to have a great affinity towards music from an early age.

Physical Affection – Hugs and kisses

Babies understand and respond to hugs and kisses. Take time to bond with your baby through cuddles and kisses, and relax and enjoy every precious moment you spend with your little one.

Share Favorite Activities with Your Baby

While it is good to take a break from your baby from time to time, you can bond with your baby by involving him or her in your favorite activities where possible. Even simple activities such as taking your baby with you for a walk in the park can be a bonding experience — you can point interesting things out to your baby, while at the same time getting some fresh air together. All it requires is a little advance planning — for example, if you intend to take your baby with you for a shopping trip, be sure to pack diapers, an extra change of clothes and any other essential items your baby may need.

Additional Point:

Be vocal with your baby’s daddy. Convey the feelings and emotions coursing through you to your husband. By sharing your frame of mind, you help to convey the ideas and insecurities that may be dwelling inside you. If you are a vivid dessert lover, ask your partner to send cake to Bangalore to elevate your spirit from time to time. Not everyone can read your mind. Always remember that! Opening up to your significant other will help you feel more connected to yourself.5

Two Important Contributions to Electromagnetism

Electromagnetism is a branch of Physics in which the electromagnetic force is studied. The study involves the interaction between the electrically charged particles. The charged particles have electromagnetic force between them, and it is a combination of electrical and magnetic forces. The electromagnetic force is one of the four fundamental forces.

In this article, we shall try to understand how the special theory of relativity and the Lorentz force is related to electromagnetism.

What is the Special Theory of Relativity?

The special theory of relativity is also known as special relativity. It is the physical theory which states the relationship between space and time. There are two postulates on which the special theory of relativity is based:

  • Laws of Physics are invariant.
  • The speed of light in a vacuum is the same as in any other space, and it is not dependent on the light source.

Relation Between The Relativity And Unifying Electromagnetism

During the theoretical investigation, wave propagation was discovered. It was a part of classical electromagnetism. A branch of theoretical physics that deals with the synergy between the electric charges and the current are known as classical electromagnetism. This study is done using the classical Newtonian model. With the help of this theory, one can understand how electromagnetic phenomena behave when the field strength and relevant length scales are large enough such that the quantum mechanical effects are negligible. This study also helped in the further development of the special theory of relativity.

What is Lorentz Force?

Lorentz’s force is defined as the combination of the magnetic and electric force on a point charge due to the electromagnetic field. The following are the two formulas of Lorentz force when there is a charged particle and a continuous charge distribution.

Lorentz Force for the Charged Particle

F=q(E+vB)

Where,

  • F is the force acting on the particle
  • q is the electric charge of the particle
  • v is the velocity
  • E is the external electric field
  • B is the magnetic field

Lorentz Force for the Continuous Charge Distribution

dF=dq(E+vB)

Where,

  • dF is the force on a small piece of the charge
  • dq is the charge of a small piece

The importance of Lorentz force is that it explains the mathematical equations and the physical importance of the forces acting on the charged particles that travel through space. This space consists of an electrical field and a magnetic field.

 

What Are Defined Benefit Pension Schemes?

Defined benefit pension schemes are also commonly known as final salary pension schemes and is essentially a pension scheme that promises to pay out an income that is the same as what your final salary was when you retired or left from that company.

Unlike many other schemes, the amount you receive in your retirement is guaranteed and is paid directly to you based on your normal retirement date of the scheme and, as a result, you don’t have to decide how you access your pension pot at any time – other than the usual choice of whether to take out lump sum or not at the start.

Just What Is A Defined Benefit Pension Scheme?

A defined benefit pension scheme is one which you and your employer continually pay into throughout the span of your career. This money is then invested into various investment vehicles over time on your behalf. However, unlike all other types of pension schemes, the amount you pay in is pretty much irrelevant when it comes to calculating your retirement income. This is because the income you receive in your retirement is guaranteed when you first agree on your pension.

There are 2 types of defined benefit pension schemes, one of which is based upon your final salary when you retire, whilst the other is based on the median salary you receive throughout your entire career.

Your pension value will also rise, also known as index-linking, which basically means the income you receive will increase each year, in line with inflation, although the actual increase will most likely be capped.

Defined Benefit Schemes And Their Lump Sum Payments

The UK Government allows retirees to take out an initial lump sum of 25% of the total value of their pension pot, tax free. Unlike other schemes where the final value is a calculation of the total amount invested, defined benefit schemes work a slightly differently.

It is still very possible to take out a lump sum, or perhaps transfer the entire amount of the pension pot altogether, but this totally boils down to how much of the lump sum you receive for every £1 of income you give up. This is called the ‘communication factor’. In simpler terms, if your communication factor is 15, for every £1 you choose to give up, you will receive £15 in return as a lump sum.

In either case, you will need to ask you pension fund provider directly on how much lump sum you will receive from your defined benefit pension scheme.

Expats And Defined Benefit Schemes

As the whole scenario for expats is now slightly different for anyone who stays in the UK, there are extra options and more risks for expats when it comes to defined benefit schemes.

As with any other investment decision, everyone’s circumstances are different and therefore there’s no hard and fast rule or preferred direction and it’s crucial that you get professional advice from a good independent financial adviser or specialist pension advisor near me, who completely understands the ins and outs of defined benefit pension schemes.

As with all investments, the wrong decision can cost you dearly and result in a significant loss.

However, in recent times, the yields of 10 year gilts have declined, which means the cash equivalent values of defined benefit schemes have seen record highs.

Also, as we mentioned earlier, as people continue to live longer, the pension fund deficit (i.e. there’s not enough in the pot to pay everyone) means that there could be a far greater risk to their income in the long term. It’s estimated that the deficit of defined benefit pensions is growing by a staggering £100bn every month, and is currently estimated at £1.54tn (according to PwC).

Synthetic Ice

Is Synthetic Ice Safe to Skate On?

Over the last year and a half or so, there has been a huge interest in synthetic ice. As it turns out, you can install the panels just about anywhere and have your own ice skating rink. Hockey players love this, and so do other ice skaters. Although there have been questions regarding the safety of synthetic ice and that it could be harmful to skaters that use it. Is it safe? You might be surprised at that answer…

What Exactly IS Synthetic Ice?

We all know that traditional ice is merely water that has been frozen into a solid form. Synthetic ice, on the other hand, is not so simple. It is made out of a complex type of plastic that is developed out of synthetic polymer material. This is known as polymer plastic.

In the early days of artificial ice, there were a considerable amount of problems in the way that the flooring had to be used. When skaters ice skated across the flooring, the only way that they could successfully glide across is if there was a constant flow of lubricant added to it as they skated. There was much to learn about plastics at that time in history.

Self-Lubricating Ice Panels

As time moved forward and researchers began to gain powerful insight and knowledge about the way that plastics could be formed, a new way of development came into the picture. Polymers are actually naturally occurring strings of molecules that make up a large amount of the matter that we see every day. In fact, our DNA is a great example of a chain polymer. 

As the knowledge of polymers became more clear, developers found that they could create a type of plastic out of man-made polymers that could include built-in lubricating agents that would allow for lubricants to be pulled from the plastic flooring to the surface as the skaters skated across it. Much like ice. 

Ice Skating on Ice

When skaters skate across the ice the blades of the skates dig into the ice and create enough heat from the friction to melt some of the ice. As the ice melts, it leaves a thin layer of water that acts as a lubricant for the skates to slide easily across and glide around the rink. We mentioned above that the synthetic ice of today is equipped with a self-lubricating ingredient that makes skating on the surface much like skating on real ice.

Harmful Vapors from Synthetic Ice? No

There is a theory going around that the blades from the ice skates cause harmful vapors to escape from the synthetic ice panels and go into the air as people skate over them. This is absolutely not true. Although synthetic ice is made out of special polymer plastic, there is no vapers that come from it when it is skated on. The only way there might be a possibility of harmful toxins that come from the panels if they were to be lit on fire.

In fact, the amount of energy that it takes to keep traditional ice frozen through the hot summer months is enough to cause much more ecological damage than synthetic ice could.

Conclusion

Synthetic ice is about as safe to skate on as traditional ice. If you can ice skate like a champion over real ice on a rink, then by all means you are just as safe on ice panels as you would be on a true ice rink. So if you want to figure skate or practice shots with a hockey shooting tarp, go ahead and do it on some ice panels. Enjoy yourself.

Where are Go-Karts Near Me in Baltimore?

Go-karting is a whole lot of fun for the entire family. It’s been an essential American pastime since the 1950s when the first go-kart was invented by Mr. Art Ingles. Ever since the inception of this great activity, the United States has been captivated by it, and continues to be captivated by it to this day. If you’re recently found yourself thinking “where can I ride go karts near me?” and you’re in Baltimore, Maryland you’re in luck. Baltimore happens to have one of the best go-karting facilities.

Satisfy Your Cravings to Go Fast

Out of all of the exciting things to do in Baltimore, go-karting has got to be in the top 5. The best part about riding go-karts is the feeling of zooming around in that tiny car. It’s a great feeling as you zoom by and take the curves expertly. With the right equipment, anyone can feel like a pro and go very fast around the course.

This is one of the reasons why Baltimore’s indoor go-kart track is so great. Their karts have a differential axel to ensure that the kart handles as smoothly as possible whether you’re the world champion go-kart racer or you’re just driving them for a fun way to spend an afternoon.

Their Italian third-generation electric go-karts are designed to be weighted in a balanced manner which helps a lot with handling, and their electric engines have 20 horsepower. That’s incredibly powerful for a go-kart, and it allows them to move up to 50 miles an hour.

Their tracks can handle up to ten karts at a time, which means that you can have the race you want with 9 other karts. Even if you’re neck and neck with someone the entire race, their advanced sensors will allow you to know who won with accuracy down to 1/100th of a second.

Make Sure You’re Safe While You Kart

Not only are these karts the fastest in the industry, but they’re also optimized for safety as well. Their balanced weight cuts down on the chances of the kart tipping or flipping, and the roll bars that are installed are there to make this chance even lower.

With their standard four point safety harnesses you can be sure that you’re getting the same kind of safety out of them that the pros do, and each kart has brake lights built in to ensure that all drivers can safely maneuver around the other drivers. Speaking of the brakes, they are high quality disk brakes so if you need to stop quickly you’ll be able to.

The facility will provide you with a helmet before you get into the kart to ensure that your head is as safe as possible, and their course is built with guard rails that are specifically designed to help lessen your impact even if you accidentally ram into it. It’s still recommended to avoid a collision if at all possible, but if you make a mistake you can rest assured that measures have been taken to ensure your safety.

These karts, because they’re electric, produce zero fumes. That means that you can hang out in the facility all day and don’t have to worry about inhaling anything nasty from the go-karts, and because of this they can hold races any day regardless of weather conditions.

Get Your Go-Karting in Style

The Italian karts ensure that you’re not only able to go fast as safely as possible but look cool while you’re doing it. When you go out go-karting it’s always important to know for sure that the facility takes your safety and fun just as seriously as you do. These both are keys to ensuring that you have a successful day out with your friends, family, date, or whoever you decide to go go-karting with.

Will a Warrant Lookup Find Criminal Records?

People look up public records on other people every day for a variety of reasons. If you’ve found yourself wanting to get as much information as possible it’s likely that you’ve found yourself wondering if you can find criminal records when you do a warrant lookup. The answer to this question isn’t necessarily straightforward, and today we’re going to explore the answer to this question while also pointing you in the right direction to ensure that you can find the information you need in the most efficient way possible.

The Simple Answer to the Question at Hand.

The main way that people go about getting warrant information is by using the resources provided by their county law enforcement. Many counties provide warrant information as well as arrest records. You can’t get both of these pieces of information at the same time, and you’ll have to do your own research to find out if the person in question was charged with the crimes they were arrested for. Needless to say, this method can take a lot of time. If you need to check in multiple counties it can take a good deal more time because you’ll need to repeat the process for each county you need to check.

There are also some counties that can’t afford to have either of these databases. It can be very costly to keep a database of this nature up and running, and when a county doesn’t have the money to keep such a database up while also paying for more critical things it’s a clear choice to skip it.

How to Find all of the Information You Need at Once.

There is an easier way to find all of the information you need. Many companies exist specifically to help people find this kind of information easily. These companies are commonly referred to as personal background check services, and they can make your personal background check a lot easier and faster.

These companies are able to operate because they check your search query against all of the thousands of public record databases they have access to. After they find the relevant results they provide everything that was found on one page for ease of reading. You can expect to find not only warrant information and criminal history but things like driving records, arrest records, court records, and much more. If there is any information about the person in question anywhere in the United States you’ll have access to it immediately after you hit enter.

From finding the personal background check service you want to use to getting your search results the whole process takes about five minutes. It’s really as easy as picking the service of your choice then filling out a short form and hitting enter.

Get the Information You Need in One Place.

While getting your information directly from law enforcement can work for some people, the vast majority of people that are looking into getting this kind of information simply don’t have the time to search through database after database to find the information they want. Luckily, personal background check services can ensure that you get the fullest picture available with as much relevant information as is available. Finding this information can help you make sure that you’re making the safest choices possible.
