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.

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.

Salivary amylase is a glucose-polymer cleavage enzyme that is produced by the salivary glands.

Many populations exhibit the following growth curve.. Here option 1, 2, 3 are correct which describe the growth. Phase B of the graph is showing a population that has reached its carrying capacity.

The carrying capacity of the individual is  the maximum number of population size of the species in a  sustainable environment which is indefinitely reach up to the limit  of no further growth.

Carrying refers to support  and Capacity means it is the ability of an organism to reproduce the maximum output, when population reaches the limit of carrying capacity then the mortality will be  greater than natality.

The importance of Carrying capacity is mainly focused on the concept of sustainability, imbalance in the environmental  and Global warming which are the causative agent, eradication of poverty and  practices are also increase the importance of carrying capacity.

Answer:

covalent bonds

Explanation:

Covalent bonds occur when two atoms—in this case oxygen and hydrogen—share electrons with each other. Because oxygen and hydrogen attract the shared electrons unequally, each end of the V-shaped H2O molecule adopts a slightly different charge. The area around the oxygen is somewhat negative compared to the opposite, hydrogen-containing end of the molecule, which is slightly positive.

Enzymes are proteins that act as biological catalysts that increase the rate if a reaction by decreasing the amount of energy needed to speed up the reaction.  Enzymes help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down. Enzymes build muscle, destroy toxins, and break down food particles during digestion.
