What is the role of your kidneys in compensating for low levels of oxygen
TEA [102]

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.

C is wrong because the question states that the disease is a recessive pattern, while C is stating that the child would only have it if it inherited dominant alleles.

B is wrong. Like D, it’s dominant over recessive and the most the child could be is a carrier.

Therefore, I believe the answer is A, the first one.
