Answer:

agouti - aaBbCc

solid color - AaBBCC

agouti black - AAbbCc

albino - AaBbcc/Aabbcc/AABBcc

Explanation: All the phenotypes that contain cc will be albinos, so they won't present any pigment deposition. Agouti black depends on the A gene to be homozygous and the B to be recessive, so the phenotype AAbbC_ is the correspondent. If A is not homozygous and B isn't recessive, we have agouti color. If B is homozygous and A recessive, we have a solid color.

You are treating a short of breath 9-year-old male with a history of asthma. on scene he presents in severe respiratory distress

Temka [501]

<span>The answer to this question would be: Heart rate 88
</span>
Respiratory distress in asthma patient can be dangerous. It won't only affect the respiratory system but also cardiovascular system. In asthma, the expiration phase is longer and harder because of the obstruction. This will cause lower amount of oxygen gain and lower amount of carbon dioxide dumped. The right ventricle also needs extra force since the lungs pressure is increased. The heart rate should be increased in this case to compensate the lower oxygen level.

Heart rate 88 is normal, not increased. This is a sign that the heart is already tired and might go arrest.
