Here's what we know:
10,000 individuals
6,840 individuals have blood type AA
2,860 individuals have blood type AB
300 individuals have blood type BB
AA genotype frequency: 68.4%
AB genotype frequency: 28.6%
BB genotype frequency: 3%
The A allele occurs 6,840 * 2 + 2,860 * 1 = <span>16,540 times, which is a frequency of 82.7%, meaning the B allele occurs 3,460 times, which is a frequency of 17.3%. In the next generation, 3%, or 750, individuals would have blood type BB.</span>
Answer:
Results in the remodeling of chromatin that can activate or inhibit gene expression
Explanation:
Alteration of histones by addition of methyl and acetyl groups are examples of chromatin remodeling complexes. These allows for the remodeling /alteration of the chromatin state to allow transcriptional machinery and other cellular processes to have access to the DNA. This way, they can either activate or inhibit gene expression. Methylation patterns inhibits gene expression while acetylation activates gene expression and so on.
The correct options are as follows:
2. THE VEGETATION IT EATS INCREASES AND THEN DECREASES REPEATEDLY WITH CHANGING SEASONS.
Some population of living organism usually undergo cyclic population changes in size. Cyclic oscillation results in repeated rise and fall in the population size of the concerned living organism over time. cyclic population changes are often brought about by interactions between populations of different species. For example, fluctuations in food availability can bring about cyclic population changes.
3. THE DEER POPULATION WILL INCREASE AND STRIP THE REGION OF VEGETATION.
The pumas and the panthers are the predators that feed on the deer. If these predators are eliminated, the number of deer in the region will increase drastically and this will be very detrimental to the health of the vegetation in the region. This is because, the deer, in their large number will feed unrestrainly on the vegetation until there is nothing left and this will affect the concerned ecosystem negatively.
4. THE ECOSYSTEM COLLAPSES.
A keystone specie refers to a specie of organism, which has a disproportionately large effects on its environment compare to its abundance or population. Such specie play crucial roles in the maintenance of the structure of the ecological community, that is, they largely determine the type and number of other specie in the community. Elimination of keystone species will leads to the collapse of the concerned ecosystem.
Answer:
Are you just playing? Why did you type this? But hello freind! Why did you report me last time on your other question. I can tell. On the bottem of my screen, I saw you reported me. With the flag. It has your name on it. Tell me why you'd reported me.
Explanation:
Have a nice day. Merry Chritsmas!
