Answer:
d) descent with modification
Explanation:
According to my research on Darwin's theory of natural selection, I can say that based on the information provided within the question the term being described is called descent with modification. This basically refers to the most dominant traits being passed down from generation to generation, and being modified little by little in each lineage. Which is done through natural selection.

The statement above is false. The blood levels of calcium is regulated by parathyroid hormone.When one is not getting adequate calcium in one's diet and the blood level of calcium is low, the parathyroid hormone will be released. The parathyroid hormone can increase the blood calcium in several ways:
1. by stimulating osteoclasts which break down bone and release calcium into the blood stream.
2. by increasing the amount of calcium re-absorbed by the kidney before it can be excreted in urine.
3. by triggering the formation of calcitriol which increases the absorption of dietary calcium at the intestines.
