kinetic energy
The energy associated with an object's motion is called kinetic energy. A speeding bullet, a walking person, and electromagnetic radiation like light all have kinetic energy. Another example of kinetic energy is the energy associated with the constant, random bouncing of atoms or molecules.
Answer: D. some components of the cycle are used as building blocks for certain anabolic pathways.
Explanation:
The citric acid cycle or Kreb's cycle is the part of the cellular respiration. It is a sequence of chemical reaction which is used by all the aerobic organisms so as to store energy by the process of acetyl CoA oxidation derived by the process of fats, proteins and carbohydrates into forms like carbon dioxide and adenosine triphosphate (ATP).
The acetyl CoA is used in the process of synthesis of fatty acids. The citrate is used for the synthesis of cholestrol. The oxaloacetate and alpha ketogluterate are used for the synthesis of aminoacids. Succinyl CoA is used for the synthesis of poryphrins and fatty acids.
Answer:
Option C
Explanation:
Option A is incorrect as mutations may be detrimental to the organism and are not always beneficial. Option B is incorrect as there are instances where mutations may enable organisms to be better adapted to the environment. Option D is incorrect as genotypes are not selected for or selected against by environmental pressures, it is only the phenotype (exhibitable/ visible traits) that can be selected for or against, hence option C is the answer.
