Proteins in the cell membrane have many functions. Which type of protein would be used primarily to transport materials in or ou
S_A_V [24]

So in this case, let's look at pore proteins. These are proteins that cross a membrane and act as a pore for the materials that need to cross the membrane.

One example of a pore protein is an aquaporin. These proteins aid in the transport of water into or out of a cell.

Therefore, the answer to your question is: A) Pore proteins.

Homeostasis is maintained by which of the following organ systems in humans?
a_sh-v [17]

A. Multiple organ systems working together

Explanation:

All of the organ systems work together to maintain homeostasis in humans because each system does something different. For example, the circulatory system delivers oxygen rich blood to the bones and the bones create new blood cells. When one thing is wrong with one system, it affects all of the systems, like a disease. Another example of this would be the central nervous systems and endocrine working together to coordinate messages to the brain about the body's state while resting and exercising to maintain homeostasis.
