Question

You are dissecting a fish in your biology laboratory section. Your teaching assistant points out a long oval structure and tells you it is an endocrine gland. Which of the following would you then know is a true statement about this structure?A) It secretes a product that is released through a series of ducts.
B) The gland's product will only interact with receptors on the cell membrane.
C) The gland's product is lipid soluble.
D) The gland produces and secretes its product into the blood

Answer 1

Answer:

The correct answer is D.

Explanation:

• A is wrong because the endocrine glands are ductless.
• B is wrong because the product is not lipid soluble therefore it can not diffuse through cell membranes.
• C is wrong because only steroid hormones (such as androgens and estrogens) and thyroid hormone are lipid soluble.

• The correct answer is D because all endocrine glands secrete their products into the bloodstream.

I hope this answer helps.
