1. The baseline metabolic rate (BMR) of the normal rat was approximately______ ml O2/kg/ hr.
2. True or false: The BMR of all three rats was appr the same before treatment?
3. Which rat had the fastest basal metabolic rate (BMR)?
4. Why did the BMR's differ between the normal rat and the surgically altered rats?
5. If an animal had been thyroidectomized, what hormones would be missing in its blood?
6. If an animal had been hypophysectomized, what effects would you expect to see in the hormone levels in it's blood and in it's BMR?

Any help would be great :-)

On the  Hidden Content - Login or Register  the baseline metabolic rate. The injected thyroxine compensated for the thyroxine lost when the pituitary gland was removed.  Hidden Content - Login or Register , therefore the thyroid gland did not produce thyroxine.

1. The baseline metabolic rate (BMR) of the normal rat was approximately__(1664)____ ml O2/kg/ hr.
2. True or false: The BMR of all three rats was appr the same before treatment? (False)
3. Which rat had the fastest basal metabolic rate (BMR)? (Normal Rat)
4. Why did the BMR's differ between the normal rat and the surgically altered rats? )Because if certain hormones that can not be produce or stimulated because of glands that are not present.
5. If an animal had been thyroidectomized, what hormones would be missing in its blood? (Thyroxine and Calcitonin)
6. If an animal had been hypophysectomized, what effects would you expect to see in the hormone levels in it's blood and in it's BMR? Hormone levels would be decreased, BMR would be decreased and  the body could not keep the metabolism and body heat at a normal range.

Any help would be great :-)
