Answer:a. The normal gene function is required for the viability of the zebrafish.

Explanation:

It is mentioned that if the gene responsible for forming stripes on its body is inactivated by mutation then fish without stripes will produced.

This will lead to the absence of phenotypic character that is strips on the fish. The other genes which are responsible for the survival of the fish will function normally thus this will be untrue that normal functioning of the gene required for expressing horizontal strips is also necessary for the survival and viability of the zebrafish.

MatroZZZ [7]

Taking multiple antibiotics at the same time contributes to antibiotic resistance. Thus, the correct option is B.

<h3>What is Antibiotic resistance?</h3>

Antibiotic resistance may be defined as a process or strategy of microorganisms that generate the capability to conquer the drugs developed to annihilate them.

Overprescription of multiple antibiotics increases the ability of bacteria or other microorganisms to survive in harsh little conditions. Still, slowly they evolve themselves and resist the situation of the high effect of antibiotic resistance drugs.

Therefore, it is well described above.

Answer:

The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.
