B
<u>Temperature</u> is NOT a density-dependent factor affecting population growth
Explanation:
Density-dependent factors mean variables that are affected by the density of the population. The opposite of density-depend is density-independent factors. These are those variables that affect the density of the population but are not affected by the density of the population.
In this case, temperatures are not affected by the density of the population. However, temperatures affect the density of the population. Most individuals can only survive within an optimal temperature range.
The rest of the choices are density-dependent variables

Answer:
D. The frequency of the Ellis-van Creveld allele is 0.0447 in the isolated population and 0.0026 in the general population, which suggests that genetic drift has occurred in the isolated population.
Explanation:
If we assume that one gene is involved in Ellis-van Creveld syndrome and we name that gene with A, then the genotype of the syndrome would be aa.
In population 1, the frequency of the syndrome is 1/150000=0.0000066(it is the frequency of the aa gentotype)
In population 2, the frequency of the syndrome is 1/500=0.002
According to Hardy-Weinberg equilibrium
p2+2pq+q2=1 (p2 is the frequency of the dominant homozygous, 2pq is the frequency of heterozygous and q2 is the frequency of the recessive homozygous).
q or the frequency of the Ellis-van Creveld allele in Population 1 is
=0.0026
q or the frequency of the Ellis-van Creveld allele in Population 2 is
= 0.0447
