Explanation:

The influence from radioactivity is inversely proportional to the number of chromosomes , since , humans have more DNA , chromosomes than the insects , and therefore , due to less chromosomes in insects , they are more resistant towards radioactivity .

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.
