The two different molecules of aquaporin will have different sequences of amino acids
Explanation:
Aquaporins are an integral type of membrane proteins. They act as water channels and their function is to transport water and other solute materials across cells membranes and thereby control and regulate the water content of the cells.
They are formed by clustering of four water channel monomers forming a tetramer.
Each aquaporin is made up of a specific linear sequence of amino acids and variations in the sequence leads to formation of different aquaporins.
There are more than 10 types of aquaporins are known. The sizes of the aquaporins differ according to their pore diameter of each type and this difference leads to the selective permeability of water across cell membranes.
Answer:
gravity
Explanation:
gravity is the reason why regular things can't float, why we land when we jump, and why we can't fly.
gravity pulls us towards the ground, towards the center of the earth (inner core)
Mechanical waves cannot move without a medium
Answer:
Plant cells have a large central vacuole, a cell wall, and chloroplasts while animal cells do not.
