Ans.
Meiosis involves a type of cell division in sexually reproducing organisms that results in formation of four daughter cells from a single parent cell, having half of the genetic material as in parent cell. Meiosis is divided into meiosis I and meiosis II.
In gamete forming cells of humans are diploid cells and have 23 pairs of chromosomes (or 46 chromosomes). Each gamete forming mother cell undergoes meiotic division to form haploid daughter cells or gametes, each with 23 chromosomes.
Thus, the correct answer is 'twenty-three' as there are 23 chromosomes present in human sex cells at the end of meiosis II.
Answer: The question is incomplete and the options are not given but here are the options gotten from another websites.
A. Narrow part.
B. Wide part
C. The flow rate are the same in both part.
The correct option is C.
The flow rate are the same in both part.
Explanation:
The flow rate are the same in both because when there is partial blockage at the artery wall, the blood flow speed will reduce or stop, therefore the blockage will be a barrier or hindrance to free blood flow and therefore, both the narrow part and wide part will receive the same level of blood flow because of the blockage and this blockage result in restricted blood flow which in one way or the other hinder oxygen supply to the heart. The blockage deposits can cause a thickened artery wall and when blood flow is restricted it causes chest pain and if it stop it can cause heart attack. Blockage deposits can be as a result of artery wall damage.
Nerve cells because skin cells keep dividing when you loose skin. Epithelial cells also divide when you loose others.

A bacteria can do all of the following 1. Photosynthesis 2. Recycling carbon which contributes to carbon cycle 3. Nitrogen fixation which contributes to nitrogen cycle These three indicated functions are significant because they perform specific contributions in the biosphere. Phosphorylation is a function which is part of the ATP process and has nothing to do with bacteria.</span>
