The action potential can move only in one direction because the recently depolarized area of the membrane is an absolute refract
Nataly [62]

Answer: Na+ channels are closed

Explanation:

The refractory period describes a period between the initiation of an action potential (where Na+ channels are active/open), and immediately after the action potential’s peak.  In the absolute refractory period, action potentials cannot be generated, as Na+ channels are in an inactive or closed state, they usually take around one or two minutes.  

After the absolute refractory period the relative refractory period (RRP) occurs. During the RRP, it is hard to send another action potential. Na+ channels are once again open, but the cell remains hyperpolarized-  its membrane potential, remains negative. Recovery from inactivation is voltage and time-dependent; Action potentials would require an influx of more positively charged ions. These must be more than a specific threshold in order to have the cells send along more action potentials which helps with figuring out stimulus intensity.

When bacteria are inoculated into a new sterile nutrient broth, their numbers don't begin to increase immediately. Instead, ther
icang [17]

Answer:The correct reason is that the bacteria must amend themselves to the content of the nutrient in the novel medium, has to produce essential amino acids, growth factors, and other enzymes in order to survive.

In the field of microbiology, to inoculate means basically to present or insert one substance into another. For example, one could inoculate a culture of bacteria with some kind of chemical constituent, or it can be said that one introduces the chemical compound into the culture of the bacteria.
