When it triggers an abnormal or vigorous immune responce, treating the antigen that would normally cause no threat as something harmful.
The right option is granulosa
cells to produce estrogens
In the female reproductive
system, FSH stimulates granulosa cells to produce estrogens. FSH acts on a single
flat layer of support cells known as granulosa cells. It makes the cells active
as they increase in size and proliferate to produce estrogens.
Answer: (1) Providing an optimized orientation of the substrate.
(2) Decreasing the ∆G in reaction.
(3) Excluding excess water.
Explanation: The active sites of enzymes increase the rate of reaction because they decrease the activation energy of the reaction,and the physical microenvironment provides an optimal orientation of the substrate relative to reactive functional groups while excluding excess solvent,such as water.
Although some active sites may have amino acids that form salt bridges with the amino acids from a substrate,not all do, so this is not a generic strategy of active site microenvironments

Answer:
Intertidal zone
Explanation:
Intertidal zone is present between low and high tide and hence, it can be above or below water. The zone is characterized by presence of nutrients and abundant oxygen as well as availability of light. The zone exhibits fluctuations in salinity and temperature as caused by waves.
