Answer:

Gene flow

Explanation:

Gene flow describes the process where genetic information migrates to another population, introducing new alleles into the gene pool and increasing the variation in that population.

Having physical barriers would prevent this exchange of information. For example, two populations separated by a mountain range or body of water would have far less chances to interact and exchange genetic material. This would make it difficult for gene flow to occur.

<span>b. The Vicar of Wakefield

</span><span>Samuel Johnson was referring to a group of English lyric poets when he coined the term "metaphysical poets". These poets lived in the seventeenth century. Their work was mainly about love, humour, love and metaphysical conceits. Their poetry was often far-fetched with unusual metaphors or similes. The metaphysical poets wrote very different poetry from the general style of the other poets of their time. They were not interested in writing about the usual images of nature or classical mythology. </span>

Answer:

The answer is:

B. Worms consuming the blood from mammals.

Algae isn't causing any harm to the sloth, rather its providing it with camouflage to hide from predators. Both creatures benefits since the algae gets to eat any parasites and other things in the sloths fur, plus they get a free ride and home in the process. The sloth isn't harmed and is helped by the algae since it provides camouflage (mutualism).

Tree frogs aren't causing harm to the trees since they are only using them to hide from predators, the tree serves as protection for the frogs and aren't harmed in the process (commensalism).

Two fish protecting each other from predators aren't harming each other in any way, rather they are protecting each other from another animal that wants to eat them (mutualism).

The worms however are harming the mammals because they are consuming the mammals blood, this is parasitism since one animal is benefiting and the other is harmed.

Hope this helps! :)
