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.
A site in the ribosome stands in for the place where a codon is being read during elongation.
Ribosomes are macromolecular machines, raise inside all containers, that act as biological protein combining. Ribosomes link amino acids together in the order particularized apiece codons of prophet RNA particles to form polypeptide chains. Ribosomes incorporate two major parts: the narrow and big ribosomal subunits.
The ribosome is everywhere being the reason for combining proteins by translating the deoxyribonucleic acid transcribed in mRNA into an amino acid series. elongation is the entertainment industry when the RNA fiber gets more interminable, on account of the addition of new nucleotides. During elongation, RNA polymerase "walks" near individual ropes of DNA, popular as the motif rope, in the 3' to 5' direction.

Air pollution is caused the burning of fossil fuels, resulting in the formation of smog and acid rain.
<h3>What is air pollution?</h3>
Air pollution is the release of harmful substances into the air which makes it unfit and unhealthy for breathing.
Substance which pollute the air are known as air pollutants.
The burning of fossil fuels causes dangerous gases to enter the atmosphere. Heavy, dense fog caused by dangerous gases mixing in the atmosphere is called smog. Acid rain occurs when dangerous gases mix in the atmosphere and fall back to the surface in liquid form.
Therefore, air pollution is caused by releasing pollutants air.
