Xylem carries water and dissolved nutrients
Answer:
D (proteins moving ions from low to high concentration across a cell membrane)
Explanation:
Active transport, by definition, is a type of substance transport that requires energy (typically in the form of ATP). Having said that, we can immediately eliminate B (aka water diffusion throughout the cytoplasm of a cell), as diffusion (osmosis in this case) does not require any expenditure/spending of energy. Next, we can cancel A and C because although they do require energy, there is no transport involved. Thus that leaves us with D. D is not only the answer because of the process of elimination but also b/c the ans. choice says that ions are being moved from low to high concentration, which is against the concentration gradient and thus requires energy.

Sea stars (or starfish) feed off the oyster beds. If the oyster beds were destroyed it would deplete the major food source of the sea stars and they would begin to diminish.
Bottleneck is an example of a genetic drift that happens when the size of a population is severely reduced.
