Answer:
B. The allele frequency of T is 0.84, and the allele frequency of t is 0.16.
Explanation:
The Hardy-Weinberg equation is:
p2 + 2pq + q2 = 1
Where:
p = the frequency of the dominant allele
q = the frequency of the recessive allele
1 = the total number of alleles
Given that 16 individuals out of 100 are unable to taste PTC, we can calculate that the frequency of the recessive allele, q, is 0.16. We can then use the Hardy-Weinberg equation to solve for the frequency of the dominant allele, p:
p2 + 2pq + q2 = 1
p2 + 2p(0.16) + (0.16)2 = 1
p2 + 0.32p + 0.0256 = 1
p2 + 0.32p - 0.9144 = 0
(p + 0.32)(p - 2.84) = 0
p = -0.32 or p = 2.84
Since the allele frequencies must add up to 1, we know that p cannot equal -0.32. This leaves us with p = 2.84. Therefore, the allele frequency of the dominant allele is 2.84, and the allele frequency of the recessive allele is 0.16.

Answer:
In plants and algae.
Explanation:
Photosynthesis takes place in organelles called chloroplasts. A typical plant cell contains about 10 to 100 chloroplasts. The chloroplast is enclosed by a membrane.

Answer:
D. Specialist Species
<h2>
What is the advantage for species to be specialists, and how can they survive in the presence of opportunistic/generalist species?</h2>
In the setting of specialized habitats or unique situations, specialized species exist. When those conditions and surroundings change, they must adapt or go extinct, thus they must survive while they still exist.
When compared to generalists, they have the benefit of efficiency, which increases the likelihood of survival and, hence, reproduction within certain settings or situations. The generalists, on the other hand, have the benefit of being able to survive in a larger variety of circumstances and have a higher probability of doing so.
Cactuses, which are plants adapted to dry environments, are an example of specialization. More generalist plant species would typically outcompete cacti in most habitats on Earth, but very few of such species could endure the harsh conditions of a desert.
Extreme environmental conditions, competition for limited resources, and "evolutionary arms races" are some of the pressures that cause specialization. Cheetahs sprint quickly both because their prey moves quickly and because quicker cheetahs will be more effective hunters and more likely to procreate. The advantage of specialization is clear when seen from the standpoint of catching the next meal on a daily basis.
My key argument is that specialization's benefits must always be viewed in the context of the environment that generated the selective pressure that resulted in specialization. Although experts are specialists because they must be, their specializations put them in danger.
