Natural selection increases the frequency of beneficial alleles in

1 answer:

7 0

Natural selection leads to increases in the mean fitness of populations and so will reduce the frequency of disease-associated alleles, but other evolutionary processes, such as mutation and gene flow, may introduce or increase the frequency of these deleterious alleles.

Agata [3.3K]

Answer:

2,855 is the size of the colony of mosquitoes after 4 days.

Explanation:

The law of uninhibited growth is given as:

$A=A_o\times e^{k\times t}$

$A_o$ = Original amount

A = Amount after time t

k = Positive constant repressing the rate of growth

We are given with:

Original population of mosquitoes = 1000

Population of mosquitoes after 1 day =1300

t = 1 day

$1300=1000\times e^{k\times 1 day}$

$k = 0.2623 day^{-1}$

Population size of mosquitoes after 4 days

$A_o=1000, k= 0.2623 day^{-1}$

A =? , t = 4 days

$A=1000\times e^{ 0.2623 day^{-1}\times 4 days}$

A =2,855.36 ≈ 2,855 mosquitoes

2,855 is the size of the colony of mosquitoes after 4 days.
