Answer:
The correct answer is option d. "Humans share a deep evolutionary ancestry with other animals that can be seen in reappearing atavisms or body parts that no longer seem to have a function".
Explanation:
A vestigial organ or vestigial structure is an anatomical feature that no longer seems to have a function, but they used to serve a purpose in an ancient form of an organism in the past. Atavisms, are vestigial organs that seem to reappear after having been lost through evolutionary change. Charles Darwin's studies on the subject made him conclude that humans share a deep evolutionary ancestry with other animals that can be seen in reappearing atavisms or body parts that no longer seem to have a function. He published his studies on human vestigial organs and atavisms in his book "The Descent of Man, and Selection in Relation to Sex".

Answer:
The correct answer is arteries.
Explanation:
The ventricles refer to the lower two chambers of the heart. The prime function of the ventricles is to pump blood to the rest parts of the body. Arteries refer to the vessels, which will be the first one to come in contact with the blood from the ventricles.
Arteries are the blood vessels, which mediate blood away from the heart to the other parts of the body like tissues and lungs. The arteries are strong, thick, and exhibit elastic walls. The distinct types of arteries comprise elastic arteries, muscular arteries, and arterioles.
