The answer is D. Precambrian.
The correct answer is option C
The frequency of the homozygous recessive genotype
In the Hardy-Weinberg equation, p is the frequency of the dominant allele, and q is the frequency of recessive allele then the frequency of genotype is represented by
p^2 = p x p = frequency of the homozygous dominant genotype ( AA)
q^2 = q x q = frequency of the homozygous dominant genotype (aa)
2 pq = p x q = The frequency of the heterozygous dominant genotype ( Aa)

Answer:
Trees have to adapt to their environments in order to survive them, from the shape of their leaves to the size of their branches. They also have had to adapt the shape of their crowns to the kind of climate they live in so that they may have better chances at survival.
In warm areas with lots of sunlight for instance, you will see broad cones as the tree takes advantage to get as much sunlight as it can. In colder areas where snow is abundant, trees will be conical in shape so as not to gather too much snow when it falls.
