1) Which in turn rat got the speediest baseline metabolic rate?

Usual Rat

2) How come did the metabolic rates differ involving the normal rat and the surgically altered rats? How well did the results compare with your prediction? They differed because the different two mice are absent the thyroid-stimulating hormone. This implies the changed rats got either a thyroid problem or pituitary gland operatively removed, which can be an important part in raising or reducing the hormone secretion.

3) If an animal continues to be thyroidectomized, what hormone(s) can be missing in its blood? Thyroxine.

4) In the event that an animal has become hypophysectomized, what effect will you expect to see in the hormonal levels in the body? The hormone levels will be lower than expected.

5) What was the result of thyroxine injections within the normal rat's BMR? The thyroxine injections caused the conventional rat's BMR to increase.

6) The thing that was the effect of thyroxine injections on the thyroidectomized rat's BMR? How does the BMR in cases like this compare with the regular rat's BMR? Was the dosage of thyroxine in the syringe too large or perhaps too small , and or just right? The thyroxine injections within the thryoidectomized verweis caused the BMR to increase. The BMR of the throidectomized rat with the thyroxine injections is somewhat lower than the normal rat's BMR with the injections. The dose was too big.

7) What was the effect of thyroxine injections on hypophysectomized rat's BMR? How does the BMR in this instance compare with the standard rat's BMR? Was the medication dosage of thyroxine in the syringe too large or too small , or just right? The hypophysectomized rat's BMR with the thyroxine injection was also increased. Compared to the normal rat's BMR, the hypophysectomized rat's BMR is a bit lower. The dose of thyroxine inside the syringe was too large.
