Answer:
There are two mitosis and meiosis.

Answer:
Pollination is the transfer of pollen from the male part of the flower, known as the anther, to the female part of the flower, known as the stigma. This can occur through a variety of methods, including wind, water, or through the action of animals. Once the pollen lands on the stigma, it begins to grow a tube down through the style of the flower towards the ovary.
Fertilization occurs when the pollen tube reaches the ovary and fertilizes the egg cell inside the ovule. The fertilized egg cell then develops into a seed, while the ovary develops into a fruit. The process of fertilization requires the transfer of genetic information from the male parent to the female parent, which occurs when the sperm cell from the pollen combines with the egg cell in the ovule.
After fertilization, the ovule develops into a seed, which contains the genetic material necessary for the growth and development of a new plant. The fruit, which develops from the ovary, provides protection for the seeds and helps to disperse them away from the parent plant. This process of pollination and fertilization is essential for the reproduction of flowering plants, and allows for genetic diversity and evolution within plant populations.
Answer:
2) JG cells are present in the vasa recta.
Explanation:
The vasa recta is a web of the blood capillary which supply blood to the medulla region of a kidney due to its high permeability of solutes and water. It runs parallel to the loop of Henle. It does not composed of the juxtaglomerular cells (JG cells). The juxtaglomerular cells (JG cells) present in kidney which synthesise and stores enzyme renin. Thus, option 2) JG cells are present in the vasa recta is not a true statement.
The Two substance that has low entropy are diamond and graphite while the other two chemical/substance that has high entropy are Noble gases(helium, neon, etc) and oxygen.
Generally, entropy measures the disorder or randomness in a system. High entropy implies randomness or high disorder while low entropy indicates orderliness.High entropy system, more energy is lost to the environment/surroundings.
Examples of chemicals or substances with high and low entropy are listed below
Low entropy
1.Diamond: This is a carbon crystalline substance. The makeup follows a well-structured pattern. The particles are tightly packed thereby giving them a low entropy value. This means they are well ordered.
2.Graphite: This is another carbon substance but they have higher entropy than diamond but generally possess a low entropy.
High entropy
Generally, gaseous substances possess high entropy, and this includes
1. Nobles gases(helium, argon, Neon, etc); These gases when placed in a closed system they exhibit high entropy. They act disorderly. They move randomly and tend to occupy every space available in the system.
2. Oxygen gas: This is another gaseous substance that exhibits disorderliness when placed in a closed system.
The arrangement of the particles and cohesive forces holding the individual particles of the substance together play a large role in determining its entropy.

Here are two examples:
Low entropy: -A carbon crystal structure at a temperature near absolute zero,
-A chunk of ice has low entropy
High entropy:- A box filled with two elements in their gaseous state, both of which are noble gases.
- Burning wood illustrates an increase in entropy heated very high temperature, with the gas "not very dense".
The entropy of a chemical system depends on its energy and its multiplicity, or how many different ways its atoms and molecules can be arranged. By adding new arrangements or energy, you increase entropy. A diamond, for example, has low entropy because the crystal structure fixes its atoms in place. If you smash the diamond, entropy increases because the original, single crystal becomes hundreds of tiny pieces that can be rearranged in many ways.
Burning wood illustrates an increase in entropy as The wood starts as a single, solid object. Fire consumes the wood, releasing energy along with carbon dioxide and water vapor, and leaving a pile of ashes. The atoms in the vapors and gases vibrate energetically, spreading out in an ever-expanding cloud. Dissolving salt in water is another example of increasing entropy; the salt begins as fixed crystals, and the water splits away the sodium and chlorine atoms in the salt into separate ions, moving freely with water molecules. A chunk of ice has low entropy because its molecules are frozen in place. Add heat energy and entropy increases. The ice turns to water, and its molecules agitate like popcorn in a popper.
Explanation:
Mainly by submerged fermentation using Aspergillus niger or Candida sp from different sources of carbohydrates, such as molasses and starch based.
that liver contains lots of germs
the liver contains an enzyme that breaks down hydrogen peroxide
that hydrogen peroxide is a powerful enzyme
When a piece of liver is dropped into hydrogen peroxide, the peroxide bubbles vigorously as the hydrogen peroxide decomposes into water and oxygen. This suggests the liver contains an enzyme that breaks down hydrogen peroxide. Thus, the correct option is C.
Catalase is a common enzyme which is found in nearly all living organisms which are exposed to oxygen gas. Catalase is a key enzyme which uses hydrogen peroxide, a nonradical Reactive Oxygen Species, as its substrate. Catalase enzyme is responsible for the neutralization through decomposition of hydrogen peroxide, thereby maintaining an optimum level of the molecule in the cell system which is also essential for the cellular signaling processes.
Catalase is an enzyme which causes or speeds up a reaction without being affected during the reaction. The enzyme catalase speeds up the breakdown of hydrogen peroxide into water and oxygen gas.
Therefore, the correct option is C.
