Answer:
The correct answer is B. In the human eye, the greatest amount of refraction occurs when the light passes from the air into the cornea.
Explanation:
The ocular refraction refers to the refraction that occurs in the light coming from the objects when crossing the different parts of the eye, causing the images to concentrate on the retina.
When the light rays, after crossing the cornea and the lens, are projected on the retina at a single point creating a clear image that is transmitted to the brain for processing, we talk about normal refraction.
Explanation:
When there are low oxygen levels in blood, the blood pH tends to lower. This is because there is an increased level of carbon dioxide in the blood that is converted to carbonic acid by carbonic anhydrase. When carbon acid dissociates, into H⁺ and HCO₃⁻ . The H⁺ influences the increase in acidity of the blood. The kidneys will excrete most of the H⁺ and retain most of the HCO₃⁻ to help maintain the right blood pH. However, most of blood pH homeostasis is maintained largely by the lungs.
