The same ligand can bind to different receptors causing different responses (e.g.. acetylcholine). On the other hand, different ligands binding to different receptors can produce the same cellular response (e.g. glucagon, epinephrine).

<h3><u>Answer;</u></h3>
Instantly transmitted
All of the information your brain receives is <em><u>instantly transmitted</u></em>.
<h3><u>Explanation;</u></h3>
- <em><u>Brain is the part of the central nervous system</u></em> together with the spinal cord.

Answer:
The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions
This would indicate that evolutionarily humans descended from the same family as the gorillas than monkeys in the view of natural selection and in genetics. Moreover, genetically, the structural foundation os the DNA of the humans and gorillas are 90% the same which suggests a greater correlation and relativity between the species.
