Question

6 true or false 1 point all bone begins in the embryo as calcium. true false 7 true or false 1 point in a simple fracture, the broken end of the bone cuts through the skin. true false 8 true or false 1 point the bone disease osteoporosis occurs when bones are weakened and become brittle, making them easy to break. true false

Explanation:

Question 6

In embryonic development, bones begin as mesenchymal tissue that differentiates into cartilage (for endochondral ossification) or directly into bone (intramembranous ossification), not as calcium. Calcium is a mineral that accumulates later during bone formation. So the statement is false.

A simple (closed) fracture is when the broken bone does not pierce the skin. A fracture where the bone breaks through the skin is an open (compound) fracture. So the statement about a simple fracture is false.

Osteoporosis is characterized by reduced bone density, weakened bone structure, and increased brittleness, which makes bones more susceptible to fractures. This matches the description in the statement. So the statement is true.

Answer:

False
