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. Hope you found this helpful! :)
Giraffes and Elephants: Giraffes have adapted a long neck over time letting them eat and access food allowing them to survive. If a dry season was unusually long they would succeed fine because they are able to eat and drink from the trees. Elephants have survived with similar tactics of eating higher up, they have rough skin allowing them to outlast the heat, and only need water after long periods of time.
C, triglyceride and cellulose
triglycerides make up lipids. cellulose is not a lipid, but a carbohydrate. carbohydrates are made from sugars :)
