Homosapians started to use tools.
True, as to why your doctor recommends you to eat more vegetables or go outside among other things to get more vitamins and stay healthy.
Answer:
0.5
Explanation:
According to Hardy-Weinberg equilibrium p2+2pq+q2=1 (p+q=1)
p2 is frequency of the dominant homozygous genotype
2pq is the frequency of the heterozygous genotype
q2 is the frequency of the recessive homozygous genotype
In the example above 80 chickens have bare legs (ff)-recessive homozygous which means that the frequency of that genotype is 80/240+80=0.25 (q2), frequency of the recessive allele is
=0.5. This means that the frequency of the dominant allele (p) is 1-0.5=0.5
So, the frequency of the heterozygous genotype (2pq) is 2*0.5*0.5=0.5
The frequency of the dominant homozygous genotype is p2=0.25
Answer:
Observations at different distances show galaxies of different ages and therefore different stages of evolution. Observations of those different galaxies helps us to learn abt galaxy evolution because observations of distant objects reveal them as they were in the past.

Answer: Positive Gravitropism
Explanation:
The root grows toward the pull of gravity while stem tissues would show negative gravitropism.
