Answer:
it increased so fast because as more and more came to be, their genes evolved to allow them to adapt to their surroundings and prededators which allowed them to live longer, strive in the envirnoment and make even more babies.
Explanation:
Let "r" stand for the recessive red hair trait. A person with red hair must have a genotype of "rr" ( one from each parent) in order to have red hair( red hair being the phenotype).
Let "B" stand for brown hair and "b" stand for not brown hair. A person with brown hair can have a genotype of "Bb" or "BB" and have a phenotype of Brown hair. This is becasue brown hair "B" is the dominant trait.

Photoreception
<h3><u>Explanation</u>;</h3>
- <em><u>Photoreception is a type of reception of light detection that lead to vision and depends on specialized light-sensitive cells called photoreceptors, which are located in the eye.</u></em>
- Photoreceptors are the cells in the retina that respond to light. There are 2 types of photoreceptors in the retina namely; rods and cones. The rods photoreceptors detect light and are located in the retina. Cone are photoreceptors that are located in the retina and detect color.
During an emergency what you would usually want to do is a so-called threat and hazard analysis - C.
You would do this because you would want to observe and note which is a source of threat for you in a certain emergency situation. You would also to this to observe the possible hazards of doing a certain action/certain actions.
Answer:
If the cancer cell's DNA is sequenced than the anticipated results will be that the cytosines in or close to the promoter region will get methylated. It has been stated that in the cancer cells one allele of p53 is mutated and the other allele, however, of exhibiting an intact promoter, does not express the protein.
Thus, it shows that the expression in the other allele gets suppressed by methylation rather than by mutation. Methylation generally takes place in CpG islands in or close to the promoter region and therefore inhibits transcription.
