What explains the cause of dwarfism?
A deficit of parathyroid hormone
Excessive level of insulin
Excessive level of somatotropin (GH)
A deficit of somatotropin (GH)
The Correct Answer is D
Choice A rationale
A deficit of parathyroid hormone would not cause dwarfism, but it could lead to hypoparathyroidism, which can cause muscle cramps or spasms due to low levels of calcium in the blood.
Choice B rationale
Excessive levels of insulin could lead to hypoglycemia (low blood sugar), not dwarfism.
Choice C rationale
Excessive levels of somatotropin (GH) would not cause dwarfism. Instead, it could lead to gigantism in children or acromegaly in adults.
Choice D rationale
A deficit of somatotropin (GH) could indeed cause dwarfism. Somatotropin, also known as growth hormone, is essential for growth and development. A deficiency can result in short stature.
