A. During aerobic respiration, cells take in O2 (Oxygen is an input of cellular respiration) and release CO2, H2O and ATP.
Cellular respiration equation (THIS IS VERY USEFUL :) ):
C6H12O6 (Glucose) + O2 (Oxygen) = 6CO2 (Carbon dioxide) + 6H2O (water) + 36-38 ATP (energy)
NOTE: Inputs are the things going in, outputs are the things being produced.
WHY THE OTHER ANSWERS ARE WRONG:
B. Not B because it mentions the process of fermentation which is anaerobic.
C. Not C because insulin has nothing to do with cellular respiration in particular but rather blood glucose level homeostasis
D. Not D because although it is partially 'correct', the actual wording (inhaled /exhaled) is incorrect as H2O is produced not exhaled. ATP energy is also produced.

Doctors recommend that infants should not be given cows milk until at least 1 yrs old, and whole milk (specifically) until she/he is 2 year or older, due to allergies and iron-deficiency anemia.

The answer is the second option.
The Hardy-Weinberg equation assumes that all genotypes occur with equal frequency, i<span>f selection can be quantified, relative fitness values can be calculated and used to appropriately modify the Hardy-Weinberg equation.
</span><span>Choices to this question are:
1---but if there is selection against one or more genotypes, equal frequency of all genotypes is not possible.
2----If selection can be quantified, relative fitness values can be calculated and used to appropriately modify the Hardy-Weinberg equation.
<span>3----Natural selection can influence the genotype frequencies predicted by Hardy-Weinberg, but allele frequencies are not affected.
</span>4----If it can be determined that selection favors a particular genotype, the Hardy-Weinberg equation should not be applied.</span>
