Question

When making models of feedback loops, biologists often use a box or oval to represent an endocrine gland. They then use different style arrows to represent hormones that glands secrete and stimulate or inhibit other glands or tissues. The various styles of arrows are shown below. Note that sometimes biologist use a combination of styles. Arrow style 5 is an example of this. It is a combination of styles 1, 2, and 4. stimulates inhibits Arrow style 1 Arrow style 2 Arrow style 3 Arrow style 4 Arrow style 5 The image below is of a model of a hormone signaling pathway. Which of the following answer choice includes the best translation of the model? Endcrine gland A Encocine and B Selected Answer: Endocrine gland A secretes a hormone that stimulates Endocrine gland B. Endocrine gland B secretes a hormone rejected by Endocrine gland A Endocrine gland A secretes a hormone that stimulates endocrine gland B. Endocrine gland B secretes a hormone that stimulates endocrine gland A. Endocrine gland A secretes a hormone that stimulates Endocrine gland B. Endocrine gland B secretes a hormone rejected by Endocrine gland A Endocrine gland A secretes a hormone that stimulates Endocrine gland B. Endocrine gland B secretes a hormone that inhibits endocrine gland A. Endocrine gland A secretes a hormone that inhibits endocrine gland B. Endocrine gland B secretes a hormone that inhibits endocrine gland A. Endocrine gland A secretes a hormone that inhibits endocrine gland B. Endocrine gland B secretes a hormone that stimulates Endocrine gland A.

Explanation / Answer

Endocrine A secrete hormone that stimulate endocrine B endocrine B secrete hormone that inhibit endocrine A

Note- the arrow shows the stimulation as we read above and straight end arrow shows inhibition.
