The saline injections will not change the rat's vertebral bone density (indicated by an unchanging T score). Predict Question 2: What effect will the estrogen injections have on the estrogen-treated rat's vertebral bone density? Your answer : b. The estrogen injections will decrease the rat's vertebral bone density (indicated by a more-negative T score). Predict Question 3: What effect will the calcitonin injections have on the calcitonin-treated rat's vertebral bone density? Your answer : a.
