Answer:
The correct answer will be option-B.
Explanation:
Cellular respiration is a slow process which produces energy from the oxidation of food components which could be glucose, fatty acids and proteins.
The process proceeds in four steps: glycolysis, link reaction, Krebs cycle and electron transport chain.
The energy molecules are produced when a high energy electron gets reduced and the released energy is stored in the form of energy molecules which could be ATP or energy equivalents like NADH and FADH₂.
These reducing equivalents donate its electrons during electron transport chain where the electrons flow to the last electron acceptor called oxygen.
Thus, Option-B is the correct answer.
Power measures work and time
power=work/time
The endoplasmic reticulum aids in the production and movement of proteins and other materials through the cell.
Natural selection is the process in which some organisms that show better adaptation to the environment are more likely to produce an offspring. In the case of the exercise, the answer is:
b. Some tuna live in the Pacific Ocean. They are fast, so they are likely to survive and pass on their genes.
It means that as they are better adapted to that environment due to the fact they are fast swimmers, they are likely not only to survive, but to pass their genes and produce offsprings.
