5 0

Answer:

The correct answer is  B. A small substance generated in response to receptor binding that activate or inactivate specific proteins.

Explanation:

An example of second messengers are AMPcyclic, Ca2 + ion. In the case of cAMP, the enzyme adenylate cyclase is synthesized from ATP (this is found within the cell membrane). The AMPC is involved in cell signal transduction pathways before external and / or internal stimuli, (example: adrenaline hormone), being able to activate the enzyme called protein kinase A (PKA), which phosphorylates its target and thus the signal is transmitted.

Answer:

C. Understand the process

Explanation:

When scientists create models of earthquakes, they are trying to learn more about them to try and keep people safe in the event that one does happen. It is practically impossible to change the location of an earthquake or stop it from occuring, since earthquakes are caused by the movement of massive continental plates. Scientists also definitely do not want to increase the waves formed in the process, as this would contribute to the damage. Therefore, the correct answer is choice C, understand the process.
