Match each function to the appropriate thyroid or parathyroid hormone. One choice will be used twice. HORMONE FUNCTION Causes blood calcium level to increase Parathyroid hormone Causes the deposition of calcium ions in the bones Calcitonin Increases the rate of metabolism Thyroid hormones Triiodothyronine Thyroxine Parathyroid hormones

Arrange the following events into an appropriate sequence. 1. high thyroid hormone concentration 2 . anterior pituitary inhibited 3. homeostasis 4. lower level of thyroid-stimulating hormone $5 .$ thyroid gland secretes less thyroid hormone (c) 1,2,5,4,3 (a) $1,2,4,5,3(b) 5,4,3,2,1$ (d) 4,5,2 $3,1(\mathrm{e}) 1,4,2,5,3$
Thyroxine, an important hormone that controls the rate of metabolism in the body, can be isolated from the thyroid gland. When $0.455 \mathrm{g}$ thyroxine is dissolved in $10.0 \mathrm{g}$ benzene, the freezing point of the solution is depressed by $0.300^{\circ} \mathrm{C}$. What is the molar mass of thyroxine? See Table $10-5$
