What is phosphorylation?

When one or more than one phosphorus / phosphoric acid forms bond with adenosine generated from the bond between a nitrogenous base and a pentose sugar Adenosine Monophosphate, Diphosphate, Triphosphate are created. Usually this phosphate addition reaction does not require external energy input and in widely known as phosphorylation.

What is meant by C4 plants?

In green plants in light independent phase of photosynthesis there are three pathways of CO2 reduction. One of it is Hatch and Slack cycle or C4 pathway. The first stable substance formed in the pathway is 4 - carbon Oxaloacetic acid. In C4 plants, at the same time both the Hatch and Slack cycle and the Calvin cycle are carried out. The rate of photosynthesis in C4 plants is higher than that of in C3 plants. Some examples of C4 plants are maize, sugarcanes, other plants of grass type, motha grass and amaranthus.

What is anaerobic respiration?

The respiration which occurs in absence of oxygen, is called anaerobic respiration. In anaerobic respiration, respiratory substances being partially oxidized with the help of enzymes, produce different types of organic compounds (ethyl alcohol, lactic acid etc), CO2 and small amount of energy. Only in some microorganisms such as in bacteria, yeast etc. anaerobic respiration occurs.

What is amitosis division?

The cell division process where nucleus of a cell divides directly into two parts is known as amitosis cell division. In this cell division at first both nucleus and cytoplasm divides into two parts. This type of cell division is found in bacteria, blue green algae, yeast etc.

What is aster ray?

In animal cells of the pro-metaphase stage of mitosis cell division, the spindle apparatus is developed from centrioles, and the centrioles remain in the two poles with rays spreading out from them. This rays are known as astral rays.

What is reductional division?

The cell division process where four daughter cells are produced from an eukaryotic cell and number of chromosomes become half comparing to the mother cell is known as reductional division or meiosis cell division. In the anthers and ovules of flowering plants, and in the testes and ovaries of animals meiosis occurs.

What is irregular cell division?

In mitosis cell division a cell divides into two and two cells divide into four cells and the process continues. But if this control is lost due to any reason, cell division continuous in an irregular way. This is called irregular cell division. Cancer, tumour etc. complicated diseases are the result of irregular cell division.

What is diploid?

At the time of the development of reproductive cells, number of chromosomes becomes half than that of the  mother cell. This situation is known as haploid. When the haploid cells are fused, the state of cell having two sets of chromosomes is called diploid.

What is meant by equational cell division?

Mitosis is termed as equational division. Mitosis is a type of cell division by which a eukaryotic cell divides into two by a special method. In this process, the nucleus and chromosome are divided once and the number, structure and properties of chromosome in the newly formed cell remain just alike the mother cell.

What is cell division?

Every living body is composed of cells. Some living bodies are made of only one cell. They are called unicellular organisms, e.g. bacteria, amoeba, plasmodium, some fungi, and some algae, some living bodies are made of more than one cell. 
These are called multicellular organisms. There are many living bodies, which are made of millions of cells. Living bodies like human beings or mango trees etc. are composed of millions of cells. Unicellular organisms increase their number (multiply) by cell division. In this process, one cell divides into two, two to four, and so on.

What is the meaning of an amitosis cell division?

Amitosis cell division occurs in lower organisms. The bodies of these organisms are composed of a single cell and their nucleus is not well-organized. Because of don't having a well-organized nucleus, an important part in cell division named spindle apparatus doesn't develop here.

Do I need car insurance?

All states except New Hampshire require car insurance (New Hampshire still requires financial liability if you have an accident and you still want to get insurance properly). If you drive without insurance, you could be fined, have your license revoked, or even go to jail.

How could I get cheaper car insurance?

Car insurance is expensive, but there are ways to make sure you don't pay more than yourself. Comparing prices with us is the best way to save money quickly on your car insurance premiums. There are many other ways to save money, such as walking or using public transport to reduce your mileage. See if you can lower your premiums with these tips and tricks.

Annual payment
Advance payments are always less effective than monthly payments, as there are no interest or financing fees.

Strengthen your protection
Alarms and immobilizers reduce theft risk. Look for Thatcham-approved devices, they’re more likely to be recognized by insurers

Avoid changes
Try not to change your car too much - you will have to pay extra for repairs or replacements

Less miles
The lower your mileage the less you will pay. But don't underestimate your mileage - it will invalidate your insurance

Compare
You can save up to £ 277 by comparing car insurance prices.

What is called nucleotide?

A nucleotide is the building block of DNA and RNA that consists of a base (one of four chemicals: adenine, thymine, guanine, and cytosine), a molecule of sugar, and one of phosphoric acid.

What is car insurance?

Car insurance covers your car's damage and gives you financial protection if you are responsible for someone else's injury or damage. Additionally, auto insurance can pay for medical bills if you or your passengers are injured in an accident or if you are hit by an uninsured or short-lived driver. Your policy protects you to a certain extent, agreed upon by you and your insurer.

What are the function of blood?

Image
Functions of blood The digested food absorbed by the wall of the intestine is transported to the cells by the blood.The excretory materials produced within the cells are carried to the excretory organs by the blood.Hemoglobin of erythrocytes of blood accepts oxygen from the lung and carry it to the cells as oxy-hemoglobin. It also carries the carbon dioxide produced in cellular respiration to the lung from where it goes out of the body.The hormones secreted by different endocrine glands are carried to different parts of the body by the blood.The white blood cells engulf the parasite entering the body by the process of phagocytosis. It also produces antigens that act as the preventives against diseases and thus increase body resistance. Body temperature is also regulated by the blood.The thrombocytes present in the blood, when coming in contact with free oxygen, helps blood coagulation. Thus the thrombocytes stop bleeding from the wounds. Read More The position and Functions of wood fibe…
