In a species of birds, wing size is controlled by a single gene that has only two alleles. The same species lives in two different forests. In one forest, the trees have less foliage and the birds' nests are more susceptible to predation. The large-winged birds are able to flee more quickly. In the other forest, the birds with smaller wings are more obscured from predators. Which of the following best describes the species of birds in the different forests? A) Selective pressures can cause alleles that are adaptive in one environment to become deleterious in another.
B) The species will eventually develop an intermediate wing size in both populations.
C) The alleles of both populations will undergo directional selection to have the same allele frequencies.
D) If genetic diversity and allele frequencies differ, the species will risk decline.

A

Explanation:

Given these two environments, the birds will both adapt differently to different pressing needs over time. But the changes made in one environment could be detrimental if that species of bird switched environments.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.

common management practices in dairy and poultry farming are: (i) proper shelter facilities and their regular cleaning. (ii) some basic hygienic conditions such as clean water, nutritious food, etc. (iii) animals are kept in spacious, airy, and ventilated place.
