2. another essential part of the scientific process is regular
communication between scientists. a good example of this is jan van
helmont's medieval recipe for the spontaneous generation of mice:
place a dirty shirt or some rags in an open pot or barrel containing a
few grains of wheat or some wheat bran, and in 21 days, mice will
appear! there will be both males and females present, and they will
be capable of mating and reproducing more mice.
play the role of a scientist and "peer review" van helmont's recipe
for producing mice. offer possible alternative explanations for the
appearance of the mice.

A peer review is a process that is used to evaluate written work before having the approval to analyze its truthfulness. That is why regular communication between scientists is of the utmost importance because it allows a better analysis of a scientific investigation to obtain a wider evaluation and with greater scientific rigor.

In this example, the following could be considered:

In the recipe for the appearance of mice we can indicate that the experiment will be successful: the mice like the closed and sheltered spaces, therefore the pot with the rags will attract them, also the fact that they have wheat, one of the main Rats food will make these come closer. The reproductive cycle of the mice is short because of that in 21 days they will have had at least one litter, so there will be both female and male mice.

I hope this information can help you.

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.
