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! :)
They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, ... However, there are radiometric dating methods that can be used on sedimentary rock, including luminescence dating
i hope this help
sorry if it wrong
Unlike women, men do not experience a major, rapid (over several months) change in fertility as they age (like menopause). Instead, changes occur gradually during a process that some people call andropause. Aging changes in the male reproductive system occur primarily in the testes.

Answer: The results will tell us about the correctness of hypothesis.
<u>Explanation:</u>
The Hypothesis is that explanation which is used as a starting of any investigation. The Hypothesis can or cannot be correct. We can test the hypothesis with scientific research.
Now a student can make conclusions about the hypothesis based on the results obtained. If results are the same as the hypothesis it means that our proposed explanation i.e hypothesis was correct but if the result differs than it means the hypothesis was not correct.
