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.

The optimal pH can be measured by looking at enzyme activity verses pH. Enzyme activity will increase up to a certain pH; above that pH, the enzyme activity will begin to fall.
Answer:
constitutive mutations
Explanation:
Constitutive mutations -
They are the strains which uninterruptedly make proteins , and therefore , can lead to excess of protiens and the process is very difficult or nearly impossible to stop , is known as the process of Constitutive mutations .
One of the example of this process of Constitutive mutations is ,
The strain with lac operon mutation which can even results in th etranscription of the lac genes .
Hence , from the statement of the question ,the correct term is Constitutive mutations .
Photosynthesis takes place inside plant cells in small things called chloroplasts<span>. Chloroplasts (mostly found in the mesophyll layer) contain a green substance called chlorophyll. Below are the other parts of the cell that work with the chloroplast to make photosynthesis happen.</span>
Answer:
Xerophyte survival characteristics:
Thick cuticle.
Stomatal closure.
Reduction in # of stomata.
Stomata hidden in crypts or depressions in leaf surface (less exposure to wind and sun).
Reduction in size of transpiration surface (lower leaf only).
Increased water storage.
Explanation:
Xerophyte adaptations increase water intake, limit water loss, and store water efficiently. Water intake adaptations include deep or widespread roots, and high salt content to increase osmosis. Xerophytes have thick cuticles, lost or finely divided leaves, reduced stomata, and CAM photosynthesis
