Single cellular organisms can rely on diffusion to move gases,nutrients,and wastes across their single membrane.What feature of the cardiovascular system overcomes this problem for multicellular organisms?
A) The cardiovascular system contains many arteries that allow for the even distribution and diffusion of gases,nutrients,and wastes.
B) Diffusion does not occur in multicellular organisms,so the distance to the environment created by being multicellular does not matter.
C) The heart pumps gas and nutrients directly to cells through arteries and allows for the removal of wastes through venous return.
D) It has high-pressure veins that can force gases,nutrients,and wastes into any area that they are needed.
E) The capillary blood vessels are found throughout the body to allow for even distribution and diffusion of gases,nutrients,and wastes.
