Answer:

Biological

Explanation:

The biological species concept differentiates one species from the others on the basis of reproductive isolation. It assumes that the two organisms that belong to different species can not interbreed to produce a viable and fertile progeny. On the other hand, the members of the same species can reproduce with each other to produce progeny. In the given example, the populations of damselflies are observed for their reproductive behavior. Since the flies of all the populations are able to breed with each other, they belong to the same biological species.

Which description distinguishes the process of meiosis from mitosis?
Nitella [24]

Answer: Unlike mitotic cells, meiotic cells undergo two divisions to produce haploid cells, allowing for genetic diversity in sexually reproducing organisms.

Explanation:

Both meiosis and mitosis are types of cell division. However, unlike mitosis that occur at one division only and yield two daughter cells with diploid number; meiosis involves two division steps:

- Meiosis I

where the parent cell is halved in chromosome number, and genetic materials are mixed between chromatids

-Meiosis II

where the two daughter cells generated in meiosis I is further divided into four haploid cells.
