Answer: Peptide bond
Explanation:
Polysacharride are monomers of carbohydrates linked together by glycosidic bonds to form long chains, also proteins are polymers of amino acids linked together by peptide bonds.
Linear chains of carbohydrates are linked together by glycosidic alpha-1,4- glycosidic linkages(between the OH group of the first carbon if the 1st monomer and the OH group of the 4th carbon of the second monomer. The branched point are linked by alpha-1,6-linkages.
In proteins the alpha carboxyl group of one amino acid react with alpha amino group of another amino acid to form a peptide bond or CO-NH bridge. Proteins are made by polymerization of amino acids through peptide bonds.

Answer:
By a definition numerical, affecting whole chromosomes (see POLYPLOID and ANEUPLOIDY), and
structural, affecting genetic arrangement within chromosomes. These are usually of a fairly major type (compare POINT MUTATION) and often cause severely adverse effects. Such structural mutations are classified into various

Explanation:
About 95 percent of the time, Down syndrome is caused by trisomy 21 — the person has three copies of chromosome 21, instead of the usual two copies, in all cells. This is caused by abnormal cell division during the development of the sperm cell or the egg cell.
Answer:
Clearcutting removes all the trees within a certain area at one time. Shelterwood cutting also removes all the trees in an area, but does it in stages over several years. Seed-tree cutting removes all the trees except for a select number of mature trees that can then reseed the area.
