compare a membrane protein to a protein in the cytoplasm?

Answer 1

Think about the environments of these proteins.

A cytoplasmic protein essentially lives in water. Therefore it must be hydrophilic.

A membrane protein is stuck in the phospholipid bilayer. So it needs to be at least a little bit lipophilic (how much so depends on its location in the membrane).

The rest, well, you gotta do your own homework to earn a grade.
