What is the significance of chromosomes crossing over during the prophase stage of meiosis?
Fittoniya [83]
Well, when chromosomes cross over during prophase 1 of meiosis, the homologous pair of chromosomes exchange segments of DNA which happen to be the genes. So the significance of crossing-over during prophase 1 is that it adds genetic variation to sexually reproducing organisms.

.A researcher alters the DNA-binding domain of a glucocorticoid receptor to that of an estrogen receptor. How would the cells re
gizmo_the_mogwai [7]

Answer:

d) They would bind glucocorticoids, and initiate estrogen-dependent synthesis

Explanation:

Both Glucocorticoids and estrogens Hormones have important but distinct physiologic functions. These two hormones belongs to the two classes of steroid hormones. Both of these hormones binds to their specific receptors.

DNA binding domain is the domain that after activation by external factors such as hormones express the specific proteins by binding to specific region of the DNA.

As DNA binding domain of a glucocorticoid receptor is altered with DNA binding domain of estrogen receptor so it means binding site of the glucocorticoid hormone for glucocorticoid receptor remains the same and binds to glucocorticoids but on binding it activates the estrogen DNA binding domain which further binds to specific region in the DNA which initiates estrogen dependent synthesis.

Why is it important to conserve forests around the world
Vikentia [17]
The conservation of forests is vital to our ecosystems, because they provide sustainable amounts of habitat for animals, who live in them. On top of that, forests provide us with a large amount of oxygen. Trees go through photosynthesis, in which they take in carbon dioxide out of our air, and give back oxygen which is vital for all living things. All that being said, conserving trees helps regulate climate control, and overall helps us have healthy ecosystems.

Sperm whales, a(n) species, maintain their populations close to carrying capacity.
soldier1979 [14.2K]
The answer is K-selected.

<span>The population size of K-selected species is fairly constant in time, unlike the population size of r-selected species. r-selected species are usually bellow carrying capacity and the population size is density independent. On the contrary, K-selected species are usually near or at carrying capacity and the population size is density dependent. It can be concluded that sperm whales have K-selected populations, since they </span><span>maintain their populations close to carrying capacity.</span>
