Question

which of the following best explains the advantage these projections provide the cell? a the projections increase the volume of the cell without affecting the surface area, which increases the metabolic needs of the cell. b the projections increase the surface - to - volume ratio of the cell, which allows for more efficient nutrient exchange with the environment. c the projections increase the speed at which an individual molecule can move, resulting in faster nutrient exchange with the environment. d the projections increase the selectivity of the membrane because the small size of the projections limits the number of transport proteins that can be embedded in the membrane.

Explanation:

Cell projections increase the surface - to - volume ratio of the cell. A higher surface - to - volume ratio allows for more efficient nutrient exchange with the environment as it provides more surface area for the same volume of the cell. This is crucial for cell function and survival.

Answer:

B. The projections increase the surface area - to - volume ratio of the cell, which allows for more efficient nutrient exchange with the environment.
