5. Which of the following is an example of active transport?
Nadusha1986 [10]

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! :)

Please help me with my question I will like and mark as brainliest ​
Ilia_Sergeevich [38]

Answer:

During exercise your cells need energy to function. in order to do so they harness it through ATP. In order to get ATP the cells convert it to ADP usually through aerobic respiration. Aerobic respiration requires oxygen to function and the cells will use up all their oxygen stores for it. Cells will get more oxygen when the exercise has been completed through the pulmonary system delivering oxygenated blood to the cells and taking away the used CO2 rich blood.

By the first distance, I'd say Venus (0.72 AU)

By the second distance, I'd say it's Saturn (9.54 AU)

But you also say it has no visible rings so the answer is VENUS.

Hope it helped,

Happy homework/ study/ exam!
