Answer:
need to be done with plenty of observation to avoid infection.
Explanation:
This technique is quite delicate because the main risk is infection. Some of the main risks are neuromuscular disease, sedation or neurological illness.
Another risk is that by passing the time, there is a difficult in respiratory, in this case, the main risk is directly to the heart, with some stoke, due to the high concentration of carbon dioxide due to the low exchange among oxygen and CO2.
Some of the indications are:
a.- Coarse crackles auscultated over trachea.
b.- Increase the respiratory pressure.
c.- Decrease tidal volume.
d.- Check the levels of oxygen in blood as in arteries.
e.- Check that patients can generate a cough.
Hope this info is useful.
The correct answer is B. The parents are heterozygous with polka-dot tails, so they both have Pp genotype. The combination of their genotypes (Pp x Pp) could produce 4 genotypes PP, Pp, Pp and pp. Therefore, there is 25% chance for a PP genotype, 25% for a pp genotype and 50% for a Pp genotype. The PP and Pp genotypes produce a polka-dot tail phenotype and the pp genotype produces a solid coloured tail phenotype. In conclusion, there is 75% chance for a polka-dot tail (25% for a PP + 50% for a Pp) and a 25% for a solid coloured tail phenotype (25% for a pp).
I’m pretty sure it’s water, oxygen, and food. beacuse food provided both nutrients and an energy source.
