Question

figure 17.1
use the diagram above to answer the following questions.
identify the letter that indicates a gland that secretes a hormone controlling basal metabolic rate.

Explanation:

Step1: Recall the gland controlling BMR

The thyroid gland secretes thyroxine, which controls basal metabolic rate (BMR).

Step2: Identify the thyroid in the diagram

In the given human endocrine system diagram, the thyroid gland is typically labeled as \( C \) (assuming standard endocrine gland diagrams: \( B \) might be parathyroid or another, \( C \) is thyroid, \( D \) could be pancreas, \( E \) kidneys, etc.). So the letter indicating the thyroid (gland controlling BMR) is \( C \).

Answer:

\( C \)
