46 chromosomes. 23 pairs. 23 chromosomes come from the egg (from the mother) and 23 come from the sperm (from the father). Haploid (containing one set of chromosomes) sperm and egg fuse to form a diploid (containing two sets of chromosomes, one from each parent) zygote.
The relation between amino acid and polypeptide is similar to the relation between nucleotide and nucleic acid.
Amino acids join together to form polypeptides, which are another name for proteins, through a series of peptide bonds. The interactions between the side chains of the polypeptide's amino acids will determine which conformation the polypeptide will fold into next.
Amino acids, which are small organic molecules with an alpha carbon atom linked to an amino group, a carboxyl group, a hydrogen atom, and a variable component known as a side chain, are the building blocks of proteins . A protein is made up of a long chain of amino acids that are connected by peptide bonds. A water molecule is removed during a biochemical process that joins the carboxyl group of one amino acid to the amino group of a nearby amino acid to form peptide bonds. The primary structure of a protein is thought to be its linear amino acid sequence.

Answer:
You have it completely right!
Explanation:
The answer is C because the chromosomes are counted by the number of centromeres which are contained on chromosomes and chromatids!
Answer:
The correct option is A. The oxygen atoms diffuse through the atmosphere and are inhaled by animals.
Explanation:
Photosynthesis can be described as a process in which plants use the light from sun to convert carbon dioxide and water into glucose. Oxygen is made as a by-product of this reaction. This oxygen is released into the atmosphere by the plants through the mechanism of diffusion.
The oxygen released into the atmosphere is taken up by animals. Animals utilize this oxygen for the process of respiration.
The process of respiration and photosynthesis are opposite to each other.
As we know vaccines have been a very controversial topic, and one of them is autism, even when this has been proved false and the original paper where it was published the study retracted, there still a number of people who argue that this is true, even when evidence in favor of vaccine safety is overwelming. Therefore the correct answer is false.
