| 1. | Regulation of metabolic rate |
| 2. | Promotion of calcium absorption in the intestines |
| 3. | Stimulation of protein synthesis |
| 4. | Increase in oxygen consumption and energy expenditure |
Dwarfism can be caused by the deficiency, during childhood, of:
| I. | Growth hormone |
| II. | Thyroid hormones |
| 1. | Only I and the dwarf will have normal mental development |
| 2. | Only II and the dwarf will also be mentally retarded |
| 3. | Both I and II and in both cases the mental development will be affected |
| 4. | Both I and II and mental development will be effected only in II. |
| I: | Thyroid hormones play an important role in the regulation of the basal metabolic rate. |
| II: | Thyroid hormones are most important factors that affect the process of red blood cell formation. |
| III: | Thyroid hormones control the metabolism of carbohydrates but not of proteins and fats. |
| IV: | Maintenance of water and electrolyte balance is also influenced by thyroid hormones. |
