4 Given below are two diagrams (one is correct, the other is somewhat incorrect) showing the transport of a hor-
mone from its source gland/cell to the target organ/cell.
(b) What is the error?

B.
Answers
Answer:
Here,A is right and B is Wrong
Explanation:
According to the given hint
(b) Error is found in diagram B
(a) Diagram "B" is showing error the secretion of hormones means the releases of that hormones outside the bloodstream which wrong because they are released by endocrine glands which secrete hormones directly into the bloodstream So there will the Release of hormones directly into the bloodstream not to the outside of bloodstream. The second Error is the release of hormones near the target cell but it's again wrong because hormones has no particular cavity to release , they get diffused in the target cell whereas the Diagram A shows The correct Transport of a hormones they get diffused in the target cell.
Information
- Hormones is an essential substance which is produced by gland of our body which travels throughout the body by the help of bloodstream and are released into the bloodstream through which they travel to target sites where they get target cell, they bind with specific protein receptors and will be activated by either a lipid-soluble (permeable to plasma membrane) or water soluble hormone (binds to a cell surface receptor). For example, the release of the hormone adrenaline, which is released by the adrenal gland. One of its target organs is the heart, where it increases the heart rate.
