A jellyfish relies on diffusion to provide oxygen to its body cells, and yet it is much larger than the 1 cm limit imposed by diffusion. How can it be so thick and still meet its metabolic demands by diffusion alone?
A)Much of the thickness of a jellyfish consists of metabolically inert materials that do not require oxygen.
B)Jellyfish have specialized tubular cells that facilitate the movement of oxygen throughout the body.
C)The layers of metabolically active tissue are very thick and highly folded, which provides a large surface area for diffusion.
D)Jellyfish maintain a very large concentration gradient for oxygen across their body tissues.
E)Water makes up most of the body of a jellyfish, and oxygen diffuses more rapidly in water than in tissues.
