Answer:
D.
Explanation:
A 'common ancestor' on a cladogram is all of those points where your lines come down and meet the primary line at the bottom.
In this case, your most recent common ancestor is at the point connected to the crocodile. All species at or past that point have that common ancestor, which include only the crocodile and the bird.
The answer is B Because fat (myelin) acts as an insulator, membrane coated with myelin will not conduct an impulse.

Explanation:
In Hardy-Weinberg equilibrium...
p represents the dominant allele frequency
q represents the frequency of the recessive allele
q^2 = the genotypic frequency of the homozygous recessive
p^2= the genotypic frequency of the homozygous dominant
2pq= the frequency of the heterozygous genotype
Further Explanation:
Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism. Mutations in DNA sequences form new alleles, and affect the corresponding mRNA and thus the protein encoded. Along with genetic drift, selective mating and natural selection, evolution may occur within populations.
Some alleles become fixed within a population over time. In Hardy-Weinberg equilibrium for a specific gene that is not undergoing evolution- allelic frequencies are stable over several generations. During this period, mutations do not occur within the population.
