Based on your knowledge of signal amplification, which chemical messenger has the greatest potential to have a large compensator

Answer:

Hormones.

Explanation:

Hormones have a really low concentration in blood but are able to trigger a large response because they bind their receptors with extreme affinity, this means that even when there are just a few molecules, they will bind the receptor. Once this interaction happens, the receptor passes the information to the inside of the cell, interacting with many other molecules that continue passing the message to generate a response. Thanks to this, a single hormone can trigger interactions between hundreds of other molecules that amplify the signal, causing a large biological response.

Answer: Vasodilation

Explanation:

vasodilation can be described as the process where the blood vessels widen within the body. Usually, it occurs when smooth muscles in the arteries and major veins relax and its major role is to distribute oxygen to different areas of the body, where it is needed most. It is a natural response of the blood vessels to low levels of oxygen or an increment in body temperature. There are certain health conditions related to vasodilation such as low blood pressure and inflammatory conditions.
