The answer is mitosis.
Mitosis and meiosis are both 2 different kinds of cell division process. In mitosis, a parent cell will divide and produce 2 daughter cells that are genetically identical to both the other daughter cell and the parent cell. Since this process produces identical cells, it is mostly used in growth, tissue repair etc.
On the other hand, meiosis is the cell division process where a parent cell produces 2 daughter cells, and the two daughter cells produces 4 more daughter cells, and these daughter cells are genetically different to each other, they only have half of the chromosomes than its parent cell. Meiosis is used in producing gametes, so that when 2 gamete fuse together, in fertilization, the zygote can retain the correct amount of chromosome.
Therefore, since skin is not used in reproduction and its chromosomes should be the same as the original skin cell, mitosis is the answer.
Answer:
1. B.
2. B.
3. A.
Explanation:
1. So, the mother does not but the father does carry the gene for polydactyly. Which means that, the offspring was born Pp and, the dominant trait (P) was exposed.
2. A heterozygous trait is one that has both allele forms (in this case, d and D. If both of the parents are Dd, the offspring will also be Dd, and therefore, he has 1/2 chance of being born deaf.
3. Both you and your spouse will be heterozygous (Ee), therefore, since unattached earlobes are dominant
3.1 When two heterozygous traits are bred, you will get the following combinations: yy, Yy, Yy and YY. Which means that your offspring had a 1/4 chance of having attached earlobes, and that is what happened.
3.2 The third option is incorrect, because when you breed 2 homozygous recessive (ee) traits, all of your offspring will be homozygous recessive (ee), which means that the parents would have to be homozygous recessive, but, they cannot since the dominant trait has applied to them.
Answer:
anything contrary to the information provided below
Explanation:
Proteins determine the shape and structure of cells and the direction of almost all vital processes. Protein functions are specific to each of them and allow cells to maintain their integrity, defense of external agents, damage repair, control and regular functions, etc. selective binding to molecules. Structural proteins agree with other molecules of the same protein to cause a larger structure. However, other proteins bind to different molecules: antibodies to specific antigens, hemoglobin to oxygen, enzymes to their substrates, regulators of genetic expression to DNA, hormones to their specific receptors, etc.

Activational effect is the correct answer.
Activational effect is an impermanent hormonal effect that leads to a change in physiological activity or behavior in both humans and adult animals. For instance, when testosterone levels rise in male songbirds they become more aggressive and tend to engage in courtship behavior. Also, a pregnant woman may get more emotional than usual due to an extra level of progesterone and estrogen during pregnancy.
