Question

7 multiple choice 1 point osteoporosis occurs when: bones become soft and flexible due to loss of calcium salts. bone density is reduced in specific areas, primarily the femur. bone resorption outpaces bone deposit. osteoclast activity is reduced. 8 true or false 1 point cartilage matrix calcification and deterioration are a normal part of endochondral ossification and interstitial bone growth. true false 9 multiple choice 1 point the cell responsible for secreting the matrix of bone is the _______. chondrocyte osteoclast osteocyte osteoblast

Explanation:

• For question 7: Osteoporosis is characterized by bone resorption (break - down) happening at a faster rate than bone deposition (formation).
• For question 8: Cartilage matrix calcification and deterioration are normal in endochondral ossification and interstitial bone growth as cartilage is replaced by bone.
• For question 9: Osteoblasts are the cells that secrete the bone matrix.

Answer:

1. C. Bone resorption outpaces bone deposit.
2. True
3. D. osteoblast
