I do believe the answer is c
Answer:
flexion - depression
extension - elevation
adduction - medial rotation
abduction - lateral rotation
Explanation:
Flexion is the process of bending an arm or leg. It occurs as a result of the contraction of the muscles. Depression is a downward movement. Hence, flexion refers to the depression of an arm or leg.
Extension is the process of stretching the body parts. Elevation is an upward movement. Hence, extension refers to the elevation of body parts.
Adduction is the movement of a limb or other part of the body towards the midline or another part of the body. The movement of the limb towards the midline of the body is known as medial rotation.
Abduction is the movement of a limb or other part of the body away from the midline of the body. The movement of the limb away from the midline of the body is known as lateral rotation.
Answer:
To show that both are evolved from a common ancestor.
Explanation:
It make the comparison between humans and chimps because the two species are so closely related to each other. Humans an chimps evolved from a single ancestor species about six or seven million years ago. Humans and chimps gradually evolved from a common ancestor due to environmental conditions that change their DNA which passed from generation to generation and bring changes in their shape and appearance as well.
