Two birds that look very similar to each other have always been considered two distinct species based on differences in their bo

dy size and in where they live. A group of ornithologists studying the two species begins to think they might not be separate species based on observed behavior. What would be the best next step regarding this new hypothesis?

The evaluation of their DNA and short tandem repeats will let them know if the birds are related or not. The genetic linkage will provide information about their common ancestry as well as if they belong to the same species, or are closely related species.

Answer:

A Genetic structure analysis

Explanation:

An analysis of genetic structure will help to know if these two groups are really different species. For that, some mitochondrial markers could be used first. Mitochondrial markers are used quite frequently for this purpose, since they usually show genetic preferences between different species. This is because they evolve faster than nuclear markers.

Anastaziya [24]

Answer:

Although direct calorimetry is considered to be the most precise technique for the measurement of metabolic rate, construction of such a chamber that is large enough for doing exercise physiology research (or any research for that matter) is extremely expensive and not at all mobile.

Explanation:

Direct calorimetry measures the heat production of an individual, in calories, when placed in an insulated chamber where the heat is transferred to surrounding water. This is a very accurate method of measuring energy expenditure.

Both the full body plate type and the half body plate trait are also present in an ocean near the lake. Where would you expect a
meriva

Answer:

In the ocean

Explanation:

Ecological divergence leads to selection of essential traits against migrants and hybrid species. The full body plate type traits requires attention for occurrence  in an environment which is free from issues such as resource limitation or predator attacks. In vast ocean spaces , resources are not a limiting factor in ocean and also there is no risk of predators as there is huge chunk of space, thus, full body plate type will occur in higher number in the ocean.

At the end of _____ and cytokinesis there are four haploid cells. At the end of _____ and cytokinesis there are four haploid cel
kotegsom [21]

Answer:

At the end of<u> telophase II </u>and cytokinesis, there are four haploid cells.cells.

Explanation:

During telophase II the sister chromosomes separate from each other and move to the opposite ends of the cell. Once that the chromosomes are in the opposite ends, the cytokinesis starts, this is the division of the cytoplasm that will give two daughter haploid cells.

We have to remember that there will be four haploid cells because there are two cells, which are the result of meiosis I, that will go into meiosis II to give these four daughters haploid cells. Also, the phases in meiosis I and II are very similar. Both of them have prophase, metaphase, anaphase, and telophase.
