The diaphragm is the large flat muscle. hope that helps :)
Answer:
The evolutionary mechanism that could be influencing the allele frequencies between both islands and the mainland population might be Founder Effect.
Explanation:
Genetic drift is the random change that occurs in the allelic frequency of a population through generations. The magnitude of this change is inversely related to the size of the original population. These changes produced by genetic drift accumulate in time and eventually, some alleles get lost, while some others might set. Genetic drift affects a population and reduces its size dramatically due to a disaster -bottleneck effect- or because of a population split -founder effect-. In <u>founder effect</u>, a new population originates when a few individuals who are coming from a bigger population carrying its genes, settle down in a new area and reproduce. This small population might or might not be genetically representative of the original one. Some rare alleles might be exceeded or might be completely lost. Consequently, when the small population increases in size, it will have a genetically different composition from the original one. In these situations, <u>genetic variability is reduced</u> and there exists the possibility of developing a peculiar allelic composition. If the number of individuals that originated the new population is low, the founder effect will be very extreme, because the effects of the genetic drift are inversely proportional to the original number of individuals.
<em>In the exposed situation, the evolutionary mechanism that could be influencing the allele frequencies between both islands and the mainland population might be Founder Effect. The fact that both islands are similar in their frequencies might be due to little genetic variation on island 1, or because dispersion to island 2 is a recent event on time. </em>
<span>The answer to this question would be:
- The permanent thermocline presents a barrier that keeps nutrients in deeper water from mixing with surface waters.
- The sunlight penetrates deep into the tropical ocean, warming the surface waters and creating stratification of water masses.
In tropical lands, the area is getting sunlight all around the year. This will cause the plant to be able to do photosynthesis all around the year too. Sunlight can penetrate the ocean, but the intensity will be much lower in deeper part. The ocean also become warmer but it will become cold in the deeper part too. </span>
SYNAPSIS: also called syndesis
the fusion of chromosome pairs at the start of meiosis.
synapsis takes place during prophase I of meiosis.
Hope this helps have a good day.....
Just say we have a big amount of tryptophan in the sense that it exceeds, tryptophan would act as a co-repressor which prevents synthesis of more enzymes for its production
Hope this helps :)
