What conditions are possible reasons for declining genetic diversity of a species? Select all correct answers.
yan [13]

Some conditions that are possible reasons for declining genetic diversity of a species;

▪︎loss of habitat

▪︎inbreeding

Explanation:

Loss of habitat will definitely reduce diversity because it reduces the population size from increased competition for reduced resources. Some subspecies may be completely eliminated when their niche is completely lost.

Inbreeding also reduces diversity because it results in the expression of recessive genes in a population that are mostly disadvantageous. High inbreeding rates will result in most individuals not reaching maturity to pass down their genes to the next generations.

Carboxypeptidase is a metallo-enzyme in which zinc is present at active site. It has been accounted for by Coleman and Vallee that the protein can be deactivated by the removal of zinc and that reactive again by the expansion of zinc, cobaltous, ferrous, nickel. which suggests that zinc is acting as the cofactor for this metalloenzyme. Zinc is a cofactor for up to 300 chemicals in the body. Proteins that utilization zinc as a cofactor is known as metalloenzymes.

Thus, the correct answer is a cofactor for enzyme activity.
