Answer:
The correct answer is <em>c.pinocytosis – liquids secreted from the cell </em>
Explanation:
<em>Pinocytosis</em> is a type of endocytosis in which substances are internalized into the cell from the celullar exterior. The components are not secreted from the cell but are uptaken into the cell. This internalization process is characterized by the formation of an invagination of the cell membrane where then is formed a vesicle surrounding the component to be uptaken.

Answer:
geographical isolation
Explanation:
Reproductive isolation is a process of evolution that ensures that members of different species are incapable of mating and when they do, such mating do not result into any offspring or leads to the production of invalid offspring.
There are two mechanisms of reproductive isolation:
- Pre-zygotic mechanisms prevents fertilization between two different species and these include habitat isolation, mating seasons, mechanical isolation, gamete isolation, geographical isolation and behavioral isolation.
- Post-zygotic isolation prevents the products of fertilization from becoming valid and this include hybrid inviability, hybrid sterility and hybrid breakdown.
<em>Geographical isolation involves the existence of geographical barriers between two populations such that there cannot be mating between the two. The two populations eventually evolve to become different species.</em>

It is <u>TRUE</u> that multiple polypeptides joined together represents the tertiary level of protein organization.
Microevolution refers to changes that occur within a single species or group or organisms. Microevolution, as opposed to macroevolution, occurs in a short period of time. In microevolution, the ancestor and the descendant obviously belong to the same type. For example, certain pests have evolved in such a way that they become immune to pesticides; the same thing has happened to certain weeds and herbicides. Hope this helps.
