Answer:
B. He has no E alleles.
Explanation:
In order for the boy to have an attached earlobes phenotype, he must have no E alleles, because the E is dominant. So his genotype must be ee. If he has even just a single E allele (like Ee) he will have detached earlobes, because the dominant trait will mask the expression of the recessive trait.
Why not A or D: Heterozygous Ee (one of each allele) would result in detached earlobes.
Why not C: If he has no recessive alleles, EE, he would have detached earlobes.

Answer:
Temperature will increase
Explanation:
As we know

Where KE represents the Kinetic Energy, R represents the gas constant and T represents the temperature.
As the kinetic energy increases, the velocity of the gas molecules increases due to which the gas molecule start moving rapidly and hence exerts higher amount of force on the wall of the container in which it is kept.
The higher force leads to generation of higher pressure and hence the higher temperature.
It is necessary because Oxygen demands need to be reduced. This may require more aggressive support
including the use of continuous positive airway pressure (CPAP) or mechanical
ventilation. Newborns born to drug-addicted mothers exhibit hyperirritability,
exaggerated reflexes, and transient tachypnea.
