Explanation:
They are called limiting factors, because they limit the amount of food resources and/or organism amount in an area or ecosystem.
Answer:
D) a cluster of stars, planets, gas, and dust all held together by gravity
Answer:
Given
The migrants proportion in the new population(m) = 0.1
Allele frequency for curved wings in the old population(q-old) = 0.6
Allele frequency for migrant population(q-migrants) = 0.2
The formulae/method to use is
(q-new) = mx(q-migrants) + (1 – m)(q-old)
= 0.1(0.2) + 0.9(0.6)
= 0.56
assuming random mating the new genotype frequency can be determined by using
fnew(cv,cv) = (q-new)^2
Where our calculated (q-new) is 0.56
= (0.56)^2
= 0.31
