Answer:

D

Explanation:

High altitude is a challenge for the human body due to the progressive reduction in barometric pressure leading to series of important physiologic responses that enable individuals to adapt and secure the oxygen supply to tissues. Reduction in oxygen pressure causes physiological responses in body which include increase in hematocrit. Also, the development of systemic hypertension is influenced by high altitude due to relative low oxygen which has significant consequences on the cardiovascular system and on blood pressure regulation. The lung response to acute altitude exposure also includes hyperventilation which aims at achieving adequate supply of oxygen to the tissues.

Therefore, regular oxygen uptake, greater ventilation, more basic hypoxic ventilation, larger lung volumes, greater diffusing capacities and increased blood pressure are typical of Jill as he adapts to the higher altitude after a month.

How are babies made?
Reptile [31]

Answer:

The genetic material in the sperm combines with the genetic material in the egg to create a new cell that starts dividing rapidly. You're not actually pregnant until that bundle of new cells, known as the embryo, travels the rest of the way down the fallopian tube and attaches itself to the wall of your uterus.
