What is the correct order of a signal being transmitted across a neuromuscular junction?
arrival of end plate potential—acetylcholine release—action potential—binding of acetylcholinesterase to its substrate
arrival of action potential—acetylcholine release—end plate potential—binding of acetylcholinesterase to its substrate
acetylcholine release—arrival of action potential—end plate potential—binding of acetylcholinesterase to its substrate
binding of acetylcholinesterase to its substrate—acetylcholine release—arrival of action potential—end plate potential

really dont know just need some points

you can't see the options

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
