Selective breeding is the practice of pairing parents who share particular features in order to produce offspring who have a greater number of desirable traits.Thus, option A is correct.
What plant and animal breeders process artificial selection?Selective breeding is the practice of pairing parents who share particular features in order to produce offspring who have a greater number of desirable traits. Humans have carefully selected a wide range of plants and animals for thousands of years, including agricultural species with higher yields.
Instead of allowing the species evolve spontaneously without human involvement, as in natural selection, people chose animals or agricultural products based on desirable qualities, a practice known as "selective breeding,” or artificial selection.
Therefore, The breeders choose organisms with the most desirable traits and breed them.

What would an organism need to do to release energy
from a carbohydrate, a lipid, or a protein? What two
elements are involved?
Organism needs enzymes in order to release energy from carbohydrate, a lipid, or a protein.
Amylase is the enzyme which is responsible for the breakdown of carbohydrates secreted by salivary glands. Pepsin, trypsin and chymotrypsin are the enzymes responsible for the digestion of proteins while on the other hand, lipase is the enzyme that is responsible for the digestion of fats in the body so we can conclude that enzymes are required by the organism for the release of energy.
