When there is light, the rod membrane potential will hyperpolarize due to the exit of cations (potassium cations) through the channel.
<h3>What is membrane hyperpolarization?</h3>
The expression 'membrane hyperpolarization' makes reference to a membrane potential that becomes negative and thus this difference is used to trigger cell processes.
In this case, membrane hyperpolarization is produced due to the exit of potassium (K+) ions of the cell and thus increase the negative charge.
In conclusion, when there is light, the rod membrane potential will hyperpolarize due to the exit of cations (potassium cations) through the channel.

Answer:
B. Individuals within a population exhibit genetic variation and those that are best adapted to their environment survive.
Explanation:
Nature poses challenges time to time to all the living organisms in the form of harsh climate, scarcity of food, natural disasters such as floods, drought, etc. Such challenges enable some organisms to survive better than the others in the same environment and are said to be selected by the nature.
This capability to survive is also termed as fitness by some scientists. Darwin however only referred to the reproductive fitness which means those organisms who are better fit in their environment produce more number of offspring than others.
Darwin used the phrase "Natural selection" for this and said it is the natural selection which is responsible for evolution.

Answer:
Sexual Reproduction. ... Organisms that reproduce sexually by joining gametes, a process known as fertilization, must have a mechanism to produce haploid gametes. This mechanism is meiosis, a type of cell division that halves the number of chromosomes. Meiosis occurs only in gamete producing cells within the gonads.
