Answer:
b. 3,2,4,5,1
Explanation:
3. The action potential induces an electrochemical process that causes release of the acetylcholine.
2. Release of acetycholine into synaptic cleft is down an electrochemical gradient, i.e through diffusion and not requiring energy input.
4. Acetylcholine then binds and activates ligand-gated ion channels of the muscle fiber to open up.
5. Sodium ions will flow into the muscle generation an action potential that will culminate into contractions.
1. The enzyme acetylcholinesterase will breakdown any acetycholine not needed in the synaptic cleft.

Oxygen is what animals need in order for Carbon Dioxide to be exhaled while breathing. This is part of what the Respiratory System does. Carbon also enters animals that are in contaminated environments such as living next to a factory or a polluted area.
Answer:
Ethanol is most likely to be a (B), competitive inhibitor.
Explanation:
The poisoing occurs because of the harmful metabolites produced by the alcohol dehydrogenases, enzymes in charge of breaking down alcohol.
Hence, the most likely strategy of an antidote is to compete for the active site of the enzyme and prevent the methanol convertion to harmful chemicals.
Ethanol does not produce these metabolites and it is preferentially proccessed by the body, so it is a competitive inhibitor, competing for the active site.
