Thegenetic codeis the set of rules used by livingcellstotranslateinformation encoded within genetic material (DNAormRNAsequences) intoproteins. Translation is accomplished by theribosome, which linksamino acidsin an order specified bymessenger RNA(mRNA), usingtransfer RNA(tRNA) molecules to carry amino acids and to read the mRNA threenucleotidesat a time. The genetic code is highly similar among all organisms and can be expressed in a simple table with 64 entries.[1]

The code defines how sequences of nucleotide triplets, calledcodons, specify which amino acid will be added next duringprotein synthesis. With some exceptions,[2]a three-nucleotide codon in a nucleic acid sequence specifies a single amino acid. The vast majority ofgenesare encoded with a single scheme (see theRNA codon table). That scheme is often referred to as the canonical or standard genetic code, or simplythegenetic code, thoughvariant codes(such as in humanmitochondria) exist.

While the "genetic code" determines a protein's amino acid sequence, other genomic regions determinewhen and where these proteins are producedaccording to various "gene regulatory codes".

The Electoral Act contains an Electoral Code of Conduct aimed at promoting “conditions that are conducive to free and fair elections” and that create a climate of tolerance, free political campaigning, and open public debate.
As soon as the election date is proclaimed, parties, their agents and candidates commit to adhering to the provisions of the Electoral Code of Conduct until the election results are officially announced. Failure to do so creates the risk of a party’s candidates or independent candidates being disqualified.

Water shortage is one of the problems facing India. There several ways to curb or rather to deal with water shortages in India. One of the ways is dig boreholes in country .Dams can also be constructed in order to store excess water from rainfall.Weirs can also be used as reservoirs for River water.

Although there is a wide range ofcryogensto produce the desired low temperature, generally liquid nitrogen (LN₂) is used in food grinding. Theapplicationof low temperature shows a promising pathway to produce higher quality end product with higher flavor and volatile oil retention.

There are some jobs for which men aregiven more preference than women. Men have a stronger physique. They canperform physically demanding jobs better than women. The jobs in which heavymachinery has to be handled are not considered fit for women. A great deal ofphysical strength and hard work is needed in jobs like mining and mechanics. Somore men are employed for such work. More men are employed in the armed forces than women.

Women, in particular, are continually excluded from some of these economic improvements. For the most part, the work associated with everyday life, such as cooking, cleaning, and looking after children, continues to fall to women. In poorer nations, these time-consuming (and uncompensated) tasks can include long journeys to gather water or firewood, but similar gender gaps are prevalent in developed nations, too. In the U.S., where the division of labor has moved toward equality in the past 50 years, women still perform several hours of unpaid labor every week in the form of care taking or housekeeping. “Women work more than men, even if a large part is relatively invisible,” the report concludes.

Atsunamiis a series of ocean waves that sends surges of water, sometimes reaching heights of over 100 feet (30.5 meters), onto land. These walls of water can cause widespreaddestructionwhen they crash ashore.

·A tsunami is a series of waves caused by earthquakes or undersea volcanic eruptions. ... Out in the depths of the ocean, tsunami waves do not dramatically increase in height. But as the waves travel inland, they build up to higher and higher heights as the depth of the ocean decreases.

The main features of production function may be stated below as-

It represents a technical relationship between physical input and physical output. It does not take into consideration money cost or price of the output sold.

The state of technical knowledge is assumed to be given and constant. It is possible that the same amount of inputs might produce higher level of output if a better technology is applied in production. Means that the same combination of two or more factors can produce more output with improved technology. It is clear that the production function changes with the change in technology, state of technical knowledge, process of production or organisation of the firm.

It states the maximum quantity of output that can be produced from given quantities of inputs. Alternatively, it shows the minimum quantities of inputs that are required to obtain a given quantity of output.

Production function, like the demand function is considered always with reference to a particular period of time. It expresses a flow of output resulting from a flow of inputs during a definite period of time.

Tsunami waves are very different from tidal waves. A tidal wave is by definition a wave caused by ocean tides, whereas a tsunami is almost always caused by anearthquakeunder water.

Tsunami waves are also very different from normal wind-generated waves, which many of us may have observed on a local lake or at a coastal beach. Observers of a tsunami will understand these waves are more like a fast moving tide crashing into the shoreline.

Furthermore, tsunami waves are much faster than wind-generated waves.

A further feature of tsunami waves is that these high-speed waves lose very little energy as they travel across the open ocean, because the rate at which a wave loses its energy is inversely related to its wave length. That is why they only propagate at high speed and with limited energy loss are capable of traveling great transoceanic distances.

Production function presumes the following main features:

1. It indicates a functional relationship between physical inputs and physical output of a firm.

2. The production function is always in relation to a period of time.

3. The production function can specify either the maximum output that can be produced from a given set of inputs or the minimum quantity of inputs required to produce a given level of output.

4. Production function is purely a technical relationship. It has no reference to money price.

5. Output in the production function is the result of joint use of factors of production.

6. The production function includes all the technically efficient methods of production.

Thus production function describes the law of production, i.e the transformation of factor inputs into outputs (products) at any particular period of time.

The principle of the Garden City was developed to solve the problem of the growing congestion and pollution of the city of London. The Garden City was a pleasant space full of plants and trees, where people would both work and live.He believed that not only it would bridge the difference between the city and the countryside and solve the housing problem of the poor, but it would also produce better quality citizens.

Ebenezer Howard developed this system in London.

India is already on its way to becoming a developed country. However, certain things are still lacking. Although, today the government of India may claim to be an emerging super power but the reality is quite different from what the government of India or the media of India portray to the world.

Eliminate Poverty

India may have progressed on paper and on screen but do we see the progress on the streets of India? Don't we still see people living in poverty. There are millions of people still surviving in India on an income of less than one dollar a day. India can never be considered a developed country unless and until the poverty, hunger and pain of the poor on the streets and those living in the slums is curbed.

Improve infrastructure

1) Roadways“If you want to be rich, you have to build roads!” Is an old Chinese Proverb. If you look at any developed country today, there is one thing they all have in common. Roads. Not two-bit highways like we have, but real 4 lane expressways stretching hundreds of kilometers without touching any major city and with real multiple grade interchanges and entry/exit points. Development does not bring roads, roads bring development. Infrastructure heaven.We have both type of roads. Good and bad ones. Turning bad ones to good will help our cause.

2) RailwaysA look at the Indian Railways will show you why biggest isn’t always best. A well-developed rail network is the hallmark of any developed country, one which allows people to travel in dignity, comfort, punctuality and space. And there will be no Tatkal system as it simply won’t be required.

3) City PlanningOur cities are usually dumps and masses of humanity. Imagine our cities being planned and built to put Singapore and Shanghai to shame with wide, clean, open roads and surroundings with plenty of open living space, cobblestoned piazzas, squares, huge parks, walkways, sidewalks, lakes with sparking water, spotless buildings and dustless atmosphere… Just think any city in the developed world.

Better Bureaucracy

One of the main things that will change the face of a country is a bureaucracy that works for it like a well oiled machine, and not a set of holier-than-thou uber-citizens who sit behind grilled and dusty ancient counters partially hidden by mounds of papers treating their salary-payers as dirt and work only at the smell of minted paper.

Better Transport facilities

Mobility will liberate India. Metros in all cities will be linked to mobility hubs where road, rail, water and air converge. This seamlessly integrated public connectivity will ensure that you will reach wherever you should in no time.

Clean rivers

It is not just the Ganga that is being choked to death. Look at any stream of water flowing through any of our cities. These will usually be stretches of tepid, stinking, toxic and stagnant black water. Now compare that with a river flowing through a city in a developed country.

If a ray of light falls normally onto a glass slab, the three optical phenomenon all happen.

A part of the ray is:

TRANSMITTED through the slab. This part of the light travels slower than it would in a vacuum, as it is now inside glass. Its wavelength would have also changed

REFLECTED at the surface, and retraces its incident path

ABSORBED by the glass, and the energy is dissipated by heating.

While most of the answers say refraction does not happen, refraction does actually happen. It is just that the ray refracts in such a way that it doesn’t deviate from the path it was initially following, i.e., there is no “bending” of light.

As we know, when exposed to wet roads, cars are in danger of skidding, due to the fact that the tyres temporarily lose their grip on the road.According to the Authority for Technical Quality Control ‘Tüv Süd,’ via the General Authority for Traffic website, drivers are able to detect initial warning signs that can indicate the potential danger of skidding. These warning signs are the sound of water hitting the wheels, the sound of water spray on the bottom of the car and the feeling of shaking while steering.

The growth of modern nationalism is intimately connected to the anti-colonial movement in India, just like in any other country.

In the process of their struggle with colonialism people began discovering their unity.

Anti-colonial movement gave a strong issue to the people with which they could identify and could come on a common platform.

All though each class or group of people felt that they were being oppressed under colonialism, the effects of colonialism were felt differently.

Hence, the growth of nationalism in the colonies is linked to an anti-colonial movement.

There are three main processes of change of population: birth rates, death rates and migration.

The natural increase of population is the difference between birth rates and death rates.

Birth Rate:

The number of live births per 1000 persons is called the birth rate. According to 2011 census, the birth rate in India is 20.22 births per 1000 persons.

Death Rate:

The number of deaths per 1000 persons is called the death rate. According to 2011 census, the death rate in India is 7.4 deaths per 1000 persons.

A higher birth rate coupled with a lower death rate results in an increase in population. Because of advancements in healthcare and nutrition, the death rate has reduced over the period.

The birth rates have also reduced because of sustained campaign towards family planning and increased awareness among people.

Migration:

Migration is another factor which changes the size of population. Movement of people from one place to another; in search of livelihood is called migration.

Migration within the country is called internal migration, while that between two countries is called international migration.

Internal migration does not change the size of the population but it changes the population composition of a particular area.

Ans :- There are three main processes of population change.

Birth ratesDeath rates andMigration.Natural increase of population is the difference between birth rates and death rates.

i. Birth rate is the number of live births per thousand persons in a year.

ii. It is a major component of growth in India because birth rates have always been higher than death rates here.

iii. Death rate is the number of deaths per thousand persons in a year.

iv. Main cause of rapid rate of growth of the Indian population is the fast decline in death rates.

Till 1980, high birth rates and declining death rates led to a large difference between birth rates and death rates.

It resulted in higher rates of population growth.

After 1981, birth rates have also started declining gradually. It has resulted in a gradual decline in the rate of population growth.

population change, which means the rate at which the population is increasing or decreasing at a given time. In this lesson, we'll go over the three main factors that cause population change:birth,migration, anddeath. Let's talk about each of these in detail.

Birth Rate

Now, this might seem very obvious to you, but when babies are born, it results in a population change! Social scientists who study this trend have some key terms, though. First, thefertility ratein a country refers simply to the number of children born. This is different from thefecundity rate, which is the number of children whocouldbe born in a given society. In other words, fecundity is the biological capacity of humans to produce children.

For a woman, this is generally the time frame between her early teens and her mid-forties. For men, this window is longer, but factors like sperm count diminish as a man ages. The fecundity rate is greater than the fertility rate in most cases. Birth rates vary by society for a number of reasons, including personal choice and social and political factors. Factors such as poverty level, access to contraception, maternal and infant care, and availability of nutrition all impact the birth rate in a society.

Death Rate

Just as when babies are born, when members of a society die it changes the population. This might be a bit morbid to think about, but scientists refer to this as themortality rate, which is simply the number of deaths that occur in a society. This is usually calculated by looking at the number of deaths per 1,000 individuals. In the United States, for example, the death rate is 8/1000 people. Just like birth rate, the death rate in a country depends on things such as availability of quality medical care, disease, war, or famine.

Migration

One important factor that accounts for a change in population ismigration. At the broadest level, migration refers to movement; it's the flow or circulation of people in societies. There are two kinds of migration: emigration and immigration.Emigrationmeans to leave one's own country for another.Immigrationmeans to enter into a country other than one's own. Both of these process impact population change.

Emigration can decrease a country's population size. For example, if you live in New York City and emigrate to Miami, you are decreasing the population of New York City but increasing the population of Miami, because you immigrated there. However, it's important to note that immigration and emigration don't change the earth'soverall population, or the number of people alive at a given time. Immigration and emigration simply change the number of people in a given place.

Today, most migration occurs when people leave rural areas and head for urban areas. Think of the word 'overpopulation.' What comes to mind? For many of us, it's likely a crowded, noisy, and polluted city of Africa or Asia. An influx of people from rural areas, who often can't sustain their families via traditional ways of life, head to cities to find work.

Theplasma membraneis selectively permeable and regulates which molecules are allowed to enter and exit thecell.

c)The mitochondrion is a double-membrane-bound organelle found in most eukaryotic organisms. Some cells in some multicellular organisms may, however, lack them.

d)In cell biology a centriole is a cylindrical cellular organelle composed mainly of a protein called tubulin. Centrioles are found in most eukaryotic cells. A bound pair of centrioles, surrounded by a shapeless mass of dense material, called the pericentriolar material, makes up a structure called a centrosome.

e)Lysosomes are specialized vesicles within cells that digest large molecules through the use of hydrolytic enzymes. Vesicles are small spheres of fluid surrounded by a lipid bilayer membrane, and they have roles in transporting molecules within the cell
