The answer is b, for he is comparing the two rocks to find an age relative to the other
It consists of skin, hair, nails, and glands. The skin protects the body from the environment on the outside. It also functions to retain body fluids, protect against disease, eliminate waste products, and regulate body temperature. It also helps store fat and water.
Hope This Helps!
Answer: Clonal progagation
Explanation:
Clonal propagation involves the production of identical individual without the fusion of germ cells. It can be multiplication through stem and other plants part such as leaves.
Strawberry as a fruits can be multiplied using the stems thus preventing the germ cells from genetic recombination that could lead to the formation of entirely new plants. It does not involve the union of male and female germ cells.
The evolution of similar forms in different lineages when exposed to the same selective pressures is<u> convergent evolution. </u>
<u></u>
Convergent or divergent evolution are related to the involved groups, the environments, the selective pressures, and the way in which organisms deal with them to achieve a better adaptation increasing their fitness.
<h3>
What is convergent evolution?</h3>
Convergent evolution is the emergence of phenotypical similarities in different groups independently from each other.
Convergent evolution occurs when two or more taxonomic groups share the same traits or characteristics even when they do not share a common ancestor.
Usually, this is a pattern observed in groups that are exposed to the same or similar environmental pressures. The development of these similar phenotypes is related to higher fitness and competitive ability.
The evolution of similar forms in different lineages when exposed to the same selective pressures is <u>convergent evolution. </u>
