Which of the following statements about the import of protein to the nucleus is correct? Choose all that apply.
dem82 [27]

The correct statements are:

•An NLS can be a monopartite or bipartite signal which includes a significant number of basic amino acids.

• The recycling of importins back to their original conformation requires GTP hydrolysis in the cytoplasm.

The other answers are incorrect because GTP is not required for an importin to bind to an NLS but for the release of importin and an NES or nuclear export signal  is the sequence  in a protein for export from the cell nucleus to the cytoplasm, not to the nucleolus.

If a gas is moved from a large container to a small container but its temperature and number of moles remain the same, what woul
Alisiya [41]
The pressure would increase. This can be explained by the ideal gas law where for an ideal gas its pressure, volume and temperature is a function of each other ans is expressed by an equation: PV = nRT. We first need to assume that this gas given is ideal. When the temperature and the number of moles is set to a constant value while the volume decreases, we can see that from the equation pressure and volume are indirectly proportional to each other, therefore as the volume decreases, the pressure inside increases.

A population of mice exists with both brown and black varieties. The mice live among sandy beach dunes where hawks prey on the m
fomenos

Answer:

Adaptation

Explanation:

In this case predation is the selection pressure for natural selection in the mice population. Because the black mice stand out against the brown sand dunes backdrop, they are easily located and predated on by the hawks. Therefore, black mice have a lower chance (compared to brown mice) to reach reproductive age and pass down their genes to the next generation. With subsequent generations, therefore, there will be more and more brown mice in the population.
