Which of the following is TRUE regarding meiosis?
Elden [556K]
C

Explanation


Meiosis 2 is similar to mitosis because it separates the chromosomes to have sister chromatids in each cell. In both processes, you are separating the chromosome and dividing the cell to make 2 cells out of 1 (the only difference is that in meiosis, you're doing that for 2 cells to get 4).

Shark pups with the most advantageous traits are more likely to survive and reproduce. For example, pups that can hunt and feed
Ronch [10]

The answer is B. This is called genetic shift. The pups with advantageous traits are able to survive until the age of reproduction hence able to pass their genes to the next generation. Few and fewer pups with disadvantageous traits will get to reproduce hence the allelic frequencies of the shark population will shift in favour of increased hunting efficiency.

7. All the recolonizing species are autotrophs. How do they get their energy?
Tresset [83]

7. The correct answer is photosynthesis.

Autotrophs are organisms which produce food for themselves-from simple to complex molecules. In the case of photosynthesis, producers (plants or some algae) use the light energy to produce complex organic compounds (carbohydrates, fats, and proteins).

8. The correct answer is primary consumers.

Since the pioneer species are usually autotrophs because there is no other source of energy except light energy in the early stages of succession (after the eruption). Most likely, the primary consumer will appear next because they feed upon producers.

9. The correct answer is: they are different populations of fish.

Those two different kinds of fish have unique adaptations that enable them to survive and live in distinct environments. It is most likely that molecular changes underlie adaptation and speciation of those fishes.
