Answer:
C) the group is paraphyletic.
Explanation:
In the classification of hominoids, the orangutan, gorilla, and chimpanzee are grouped together into the Pongidae family; while humans are placed in another family (Hominidae) because this classification recognizes to Pongidae as a paraphyletic group. The paraphyletic groups are the taxa that have a common ancestor and include some (instead of everyone) their descendants. In this case, the Pongidae family is composed of genera that descended from one ancestral species but does not include the complete list of the descendants of that species.

Explanation:
The artery is the blood vessel that carry oxygenated (oxygen-rich) blood away from the heart while the vein carry deoxygenated(oxygen-poor) blood from the body to the heart.
Hence, all arteries carry oxygenated blood except pulmonary artery while all veins carry deoxygenated blood except pulmonary vein.
Human evolution known to be a process in which species adapt to certain conditions of life, and in the battle of life and death, they are forced to become stronger in order to survive in this world. Diseases have always been present during the evolution, acting themselves as a natural selectors - the weaker organisms get sick and die. Not just humans, but all species have to establish a great protecting mechanism in order to survive. That is how our bodies are built, to be able to withstand and survive in the conditions we live in, and that is why our immune system has to be taken care of.
Hope this helped :)
