A muskrat population is growing exponentially. What might cause this population to enter logistic growth?

Answer: One cause that might cause the population of this semi aquatic rodents to enter a logistic growth would be the elimination of predators from their environment and the increase of food. The reason being that they are rodents with an adaptable lifestyle and an omnivorous diet. With no predators they would quickly adapt to their environment and increase their birth rate.

I hope it helps, Regards.

mixer [17]

Answer:

The environment the moths lived in used to be unpolluted. This made dark moths rare. As the area where light moths were found became more polluted, the light moths became less common in the polluted/dark areas. Light Moths began to evolve after not being able to survive in dark forests, they began to get darker and blend in with the polluted area to be safe from predators.

100 individuals whose genetic makeup is composed of 20% recessive alleles join an established population. The established popula
NeX [460]

Answer:

population = 600

heterozygotes = 2pq

The homozygous recessive percentage = q^{2}

q = 0.1

Solve for q:

∴ q = \sqrt{q}

∴ q = \sqrt{0.10}

∴ q = 0.316

solve for p:

for p + q = 1,

thus p = 1 – q = 1 – 0.316 = 0.684  

The heterozygotes = 2pq

2pq =  2 x 0.316 x 0.684 = 0.432

600 x 0.432 = 259.2  = 259

so,  the population reaches Hardy Weinberg equilibrium, 259 of indviduals should be heterozygous for this trait.

Hence, the correct answer is 259 .
