To pass through the cell membrane, some molecules need to pass through a(n) because they are too big to simply pass through the phospholipids
a. osmosis channel
b. nuclear pore
c. diffusion channel
d. protein channel

Protein channel.

Explanation:

Protein channel or channel proteins are present in the plasma membrane that carries the sequence of specific amino acids. These channel proteins are important for the transport of molecules inside the cell.

Generally, hydrophilic and large molecules enter through the channel proteins as their size is large to directly pass through the membrane. The cellular ATP is not required for the passage way of molecule.

Thus, the correct answer is option (D).

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
