The right answer is non rebreather.
A non-rebreather mask (NRB) is mainly used to provide oxygen to treat hypoxia, in which arterial blood oxygen saturation is less than 90 percent.
Non-rebreather masks offer an increased level of moisture towards the nasal passage, which can become inflamed and irritated with prolonged oxygen treatment. Increased humidity also increases the patient's respiratory secretions.
Answer:
this is the answer to number 2
Explanation:
the answer is nutrients and energy
There are several techniques used to evaluate the activity of the brain, each technique has its own mechanism. One of the most known technique with repeated scans is Computed tomography.
Computed tomography (CT) is a technique that <span>includes repeated scans to allow researchers to see the brain at work. the x-ray beams are aimed at the subject's head then sampled by one of the many detectors in the machine.</span>
<span>If
the population is separated long enough, this means that random sampling in mating
and reproduction, that occurred in the
initial population has been restricted</span><span>. The two population will, therefore, adapt to
their local environments and become reproductively isolated
with time. After long periods of time, the two lizards population will have different
alleles and will not be able to mate and
produce viable offsprings hence will have
speciated.</span>
