The right answer is A. lens
The eye-lens is a natural convergent lens of the eye.
The eye has two natural convergent lenses: the cornea, located at the entrance of the eye, and the crystalline, biconvex lens located behind the iris and connected to the envelopes of the eye by the ciliary body. These two lenses focus the light rays on the retina, which acts as a screen in the back of the eye.
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.
True, viral STIs are not curable and can only be controlled with medications
Answer:
Some examples of anaerobic respiration include alcohol fermentation, lactic acid fermentation and in decomposition of organic matter. The equation is: glucose + enzymes = carbon dioxide + ethanol / lactic acid. Though it does not produce as much energy as aerobic respiration, it gets the job done.
