Answer:
Cyanobacteria, Anabaena and Azotobactor are called Nitrogen fixing bacteria. These bacteria change the nitrogen in the atmosphere into a form that is used by the plants to make proteins. Plants take nitrogen in the form of nitrates. The atmospheric nitrogen is first converted into ammonia after that ammonia is converted into nitrates and this nitrates use by the plants to make proteins.
I think b. Proteins are polymers of amino acids is the correct answer
Answer: choice B. Climate
Explanation:
Climate is the relative temperature of a region over time.
Answer:
The correct sequence is
1st step- Option C
2nd step- Option B
3rd step- Option A
Explanation:
Initially, when a person swallows the food, it goes into the stomach through a muscular type of tube which helps in the transportation of food items and liquids from the mouth into the stomach, which is commonly known as the esophagus.
After passing through this tube and reaching the stomach, the liquid and food items mix up with the juice that it produces, and eventually releases its particles into the small intestine. These transported particles are known as chyme.
As the food particles reach the small intestine, its muscles allow the food particles to mix up with the digestive juices that are released from the organs namely liver, pancreas, as well as the intestine and helps in the proper digestion of the food. The walls of the small intestine extracts the nutrients that are digested into the bloodstream, where the blood supplies the nutrients into the remaining parts of the body.
After the food is digested and nutrients are absorbed into the body, the remaining waste products or undigested particles are transported to the large intestine, where it extracts the water and converts the waste particles into the stool, which are later eliminated from the body.
Thus, the correct sequence is arranged above.
Inhibin inhibits the secretion of FSH only.
<h3>What is the role of inhibin?</h3>
- Inhibin is a protein mainly produced by the gonads.
- In men it is produced by the Sertoli cells and it is produced by the granulose cells in women.
- It negatively regulates the secretion of Follicle Stimulating hormone (FSH) from the pituitary gland.
- FSH itself induces the production of inhibin for negative feedback.
- Pituitary is a pea shaped endocrine gland present at the base of the brain. It is the major endocrine gland and controls growth, development and functions of other endocrine glands.
- Hormone activin has opposite effect to inhibin. It enhances FSH biosynthesis and secretion.
