Genetics is the study of ________.
butalik [34]

Answer:

Option-B

Explanation:

Heredity refers to the passing of the traits from the parents to the offsprings or generation and also known as inheritance and Genetic variation is the difference in the genetic material in population which leads to the formation of a variety of traits.

Since the variation in traits is determined by factors (Gregor Mendel) later called "genes" which are passed on to the offsprings, therefore, the branch of biology which studies the pattern of inheritance and variation is known as "Genetics". Gregor Mendel is known as the Father of Genetics.

Thus, Option-B is the correct answer.

Describe how the output of the Krebs cycle can be modified in additional processes of the carbon cycle.
Murljashka [212]

Answer:

Step 1. A carboxyl group is removed from pyruvate, releasing a molecule of carbon dioxide into the surrounding medium. (Note: carbon dioxide is one carbon attached to two oxygen atoms and is one of the major end products of cellular respiration. ) The result of this step is a two-carbon hydroxyethyl group bound to the enzyme pyruvate dehydrogenase; the lost carbon dioxide is the first of the six carbons from the original glucose molecule to be removed. This step proceeds twice for every molecule of glucose metabolized (remember: there are two pyruvate molecules produced at the end of glycolysis); thus, two of the six carbons will have been removed at the end of both of these steps.

Step 2. The hydroxyethyl group is oxidized to an acetyl group, and the electrons are picked up by NAD+, forming NADH (the reduced form of NAD+). The high- energy electrons from NADH will be used later by the cell to generate ATP for energy.

Step 3. The enzyme-bound acetyl group is transferred to CoA, producing a molecule of acetyl CoA. This molecule of acetyl CoA is then further converted to be used in the next pathway of metabolism, the citric acid cycle.
