Explanation: Pepsin works best at a pH of 2. And as the stomach has a very acidic condition, pepsin works well. But in the small intestine, the pH is about 8, which is too high for pepsin to function. Therefore, pepsin gets denatured in the small intestine.
Answer:
Cell A is laterally being inhibited by other neighbouring cells.
Explanation:
Cell A showing lower activity compare to cell B despite both having high simulation is because Cell A is surrounded by neighbouring cells and these neighbouring cells hinder the action potential of cell A through their numerous activity they perform around cell A.
Therefore they restrain the activities of cell A.
