The correct answer is B
The genetic codes language in all living organisms is the same. This is to say that the molecules of life namely DNA and RNA share the same make up in all living things .
There are five types of nucleotides in nature which are the building blocks of RNA and DNA and these are the same in all living organisms . These nucleotides are Adenine, Thymine, Guanine, Cytosine and Uracil.
According to base pairing rules, in all DNA molecules Adenine will always pair with Thymine while Guanine will always pair with Cytosine.
This rule is the same with RNA except that here Thymine is replaced with Uracil. Otherwise the base pairing rule applies in all living organisms, that is to say it is universal.
Answer: (c) It generates ATP, which cells can use to do work.
(d) It generates chemical gradients, which have potential energy.
Explanation:
The overall process of Cellular respiration is the aerobic break down of organic compounds (food) with the release of CO2, water and energy in form of ATP which drives most cellular work.
Organic compound + oxygen --------> carbon dioxide + water + energy (ATP + heat)
In cellular respiration during the break down of food in glycolysis and the citric acid cycle, chemical energy (NADH and FADH) are extracted from each cellular process and transported to the electron transport chain built in the inner mitochondrial membrane. The chemical energy harvested from food is transformed into a proton-motive force, a gradient of H+ across the membrane. When this H+ election fall from their gradient via ATP synthase, Chemiosmosis couples this proton motive force to phosphorylate ADP to form ATP.

The correct option is (C) The neuron’s membrane voltage becomes more positive.
The resting neuron has a voltage across its membrane which is called the resting membrane potential. There is a concentration gradient of ions across the membrane when the neuron is in the resting state.
Inside the membrane the concentration of K⁺ and organic anions are more. Outside the membrane the concentration of Na⁺ is more. The membrane is much more permeable to K⁺ than Na⁺ .
The cell’s inside is more negative than the outside when the membrane is hyperpolarized. In neurons the resting membrane potential is close to the equilibrium potential for K⁺.

One of the difference is that fishes have single circulation but humans have double circulation of blood.
