Here is the complete question for easy comprehension

Fatty acid synthesis is regulated by hormone depending on feeding vs. fasting and recent exercise vs. no recent exercise. Which hormone is active after a meal and what is the mechanism of its action?

A. Insulin stimulates the mobilization of fatty acids for β oxidation.

B. Insulin stimulates fatty acid synthesis by activating acetyl CoA carboxylase.

C. Epinephrine stimulates the mobilization of fatty acids and stimulates their accumulation as triacylglycerols.

D. Glucagon activates the carboxylase by enhancing the phosphorylation of AMPK.

E. Epinephrine stimulates AMPK, preventing the phosphorylation of acetyl CoA carboxylase.

The ANSWER IS SURELY B

B. Insulin stimulates fatty acid synthesis by activating acetyl CoA carboxylase.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
