Question

Choose the correct answer from the alternatives given.
The pituitary detects a rising hormone concentration in blood and inhibits the gland secreting the hormone. This is a feedback loop.

• A. positive
• B. long-term
• C. negative
• D. both (b) and (c)

Answer 1

The correct option is C negative

Both hypo and hyperactivity of an endocrine gland produce structural or functional abnormalities of diseases. Hence, the normal functioning endocrine glands and the level of hormones in the body needs to be regulated. This is possible by a feedback mechanism. The feedback mechanism may be positive or negative. Negative feedback keeps the concentration of a hormone within a narrow range.

So the correct answer is negative.
