Question 7

Which of the following statements about blood is correct?

Accepted Answer

Blood is a liquid connective tissue with a fluid ground substance called plasma.

Question 8

Which of the following equations best represents the relationship between bone mineral density ($$BMD$$), calcium content ($$C$$), and bone volume ($$V$$)?

Accepted Answer

$$BMD = \frac{C}{V}$$

Question 9
