The population ecologist is trying to determine the density of the oak
trees in a forest. It is a part of the job of a ecologist. By detecting
the density of the oak trees, an ecologist can easily determine whether
the density of the oak trees are decreasing or increasing with time and
what are the steps that need to be taken to keep the balance.
<u> Matching grassland descriptions to correct terms </u>
A) Temperate grassland where prairie dogs can be found :
B) Temperate grassland in the eastern portion of midwest
C) Tropical grassland that is home to large herds of grazing animals
D) Temperate grassland with grasses that grow two to three feet tall :
<h3> Types of grasslands </h3>
The savannah is grassland area with more grasses than trees while the trees are occasionally present, the amount of rainfall here is moderate and the weather conditions are moderate as well, prairie dogs are found in this kind of vegetation.
Short grass prairie experiences little rainfall which favors the growth of short grasses while Mixed grass prairie is a mixture of both short and tall grasses. It is home to many herbivorous animals.
Hence we can conclude that the answers matching your description is a s listed above.

Answer:
B. 0.42
Explanation:
Since the two alleles are at Hardy-Weinberg equilibrium, the sum of the frequency of two alleles will be one. If the frequency of a dominant allele is "p" and that of the recessive allele is "q", then p+q=1
According to the given information, the frequency of one allele in the population is= 0.7
This means that the frequency of the other allele would be= 1-0.7 = 0.3
Frequency of heterozygote in the population =2pq = 2 x 0.7 x 0.3 = 0.42
