Answer:
The option that says: Sister chromatids separate from each other and migrate to opposite ends of the cell.
Explanation:
This question wants to test us on a very interesting part in genetics that is Cell Cycle, Mitosis and Meiosis.
In mitosis, the cell divide to produce or generate two daughter cells that has the identical genetic infomation just as the one in the parent cell. After mitosis, we have Cytokinesis.
For meiosis, it is divided into two that is meiosis I and meiosis II. Meiosis I is about the separation of homologous chromosomes pairs while meiosis II is about the separation of chromosome into two chromatids.
In anaphase II of meiosis, "Sister chromatids separate from each other and migrate to opposite ends of the cell" after the division of the centromere.

d)A...B...C
Explanation:
Hormones are chemical proteinous substances secreted in one location and transported to another location, in order to bring about a physiological effect. Hormones are secreted by endocrine glands which collectively makes up the endocrine system. Endocrine glands include testes, ovary, pancreas, thyroid, adrenal gland etc. A hormone is usually secreted when a change needs to be effected in a target cell.
What happens is that, when a particular physiological effect is needed by a target cell e.g growth, development, homeostasis, repair etc., it sends a negative feedback to the gland that is responsible for the secretion of the specific hormone. The particular endocrine gland, then, secretes the hormone into the bloodstream (ductless), which carries it for absorption by the target cell where it is needed.
Protons are positive and 1 atomic mass unit (or AMU), neutrons are neutral and 1 AMU, and electrons are negative and have no real weight.
