Answer:
The cuticle is a transparent outer layer of the hair shaft. It is made of scales that overlap one another and protect the inner layers of the hair (Figure 3-4). The scales point from the proximal end of the hair, which is closest to the scalp, to the distal end, which is far- thest from the scalp
Explanation:
The atlantic cod (gadus callarias) is a fish which lays about 5 000 000 eggs in its lifetime. On average, only two of these eggs survive to become adult cod. This promote evolution because the environment selects the most evolved animals to survive that environment.
<h3>What is the evolutionary process?</h3>
Evolutionary processes aim, therefore, to generate greater adaptation of species in an environment. When new species of organisms are formed from gradual changes in preexisting species.
So although there are several eggs initially only those that survived the environment are able and evolved to reproduce, so the evolution of species is carried out.
