Answer:
It is a type oe of receptor present in our body
Explanation:
It's is a type of receptor located in our noses which Helps us to smell different things. Some times when we get a cold the olfactory receptors get blocked and this prevents us from smelling things. And this also effects our sense of taste
Suppose that the proportion of the white crest alleles (r) is given by w and that of the Red crest allele (R) is given by p. We have that p+w=1. The probability that an individual has 2 r alleles is given by w*w since for each allele position the probability is w. Only these individuals have a White phenotype. Hence, we get that w^2=

; the right hand side is the proportion of white birds in the total population. Doing the calculations, this yields that w=0.37. From this, we calculate that p=0.63. The possible ways we have heterozygous individuals are the combinations Rr and rR. The probability for each of those is p*w. Thus, the total probability is 2pw. This is equal to 0.466=0.47. This is the fraction of the future population that is going to be heterozygous assuming the conditions of the Handy-Weinberg equilibrium like random reproductive matching etc.
C) water and energy ATP
The end products of respiration.
I'm pretty sure it's Cell membrane
Convective zone is the answer. If you need an explanation just ask.
Hope this helps :)
