The plasma membrane serves many functions, many of which depend on the presence of specialized membrane proteins. What roles of the plasma membrane could still occur if the bilayer were lacking these proteins?

b is the best answer for this question.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
