We alter carrying capacity when we manipulate resources in a natural environment. If a population exceeds carrying capacity, the ecosystem may become unsuitable for the species to survive. If the population exceeds the carrying capacity for a long period of time, resources may be completely depleted and Then the population size remains relatively the same. If abiotic or biotic factors change, the carrying capacity changes as well. Natural disasters can destroy resources in an ecosystem. ... If a population exceeds carrying capacity, the ecosystem may become unsuitable for the species to survive.
Explanation:
Answer:
C) 91%
Explanation:
First,
Express the Dominant phenotype as homozygous dominant(BB) and heterozygous(Bb).
Based on hardy-Weinberg equilibrium,
homozygous dominant (BB) Brown eye individuals will have the following percentage
B × B
(Where B = 70%)
70% × 70%
= 49%
heterozygous dominant (Bb) Brown eye individuals will have the following percentage
Using 2 × B × b (where B =70% and b = 30%)
2 × 70% × 30%
= 42%
The proportion of the subsequent generation with brown eyes
(homozygous dominant, BB + heterozygous dominant, Bb)
= 49% + 42%
= 91%
The answer to this obvious question is true
