Answer: 46

Explanation: 46 chromosomes are present in the cell before the start of meiosis.

The number of chromosomes that are present in the cell before the start of meiosis is 46. Because the total number of chromosomes in a human cell is 46.

Chromosomes are the thread-like structure present in pairs in all organisms. They are present inside the nucleus, and contain genes and DNA in them, and are responsible for the traits of an organism.

Meiosis is a process completed in two stages, and each contains four phases. It occurs in the germ cells, divides the cell into four cells, and reduces the number of chromosomes.

The number of chromosomes in humans is 46, 23 in pairs. Before meiosis, the number of chromosomes will be 46 after Meiosis the number reduces.

Thus, there are 46 chromosomes in the cell prior to the onset of meiosis.

In logistic growth, a population's per capita growth rate gets less and less as population size approaches a maximum charged by limited resources in the background , known as the carrying capacity.

The logistic population boost occurs when the growth rate of drops as the population reaches the carrying capacity.

In logistic growth, population growth declines as resources become low, and it fells off when the carrying capacity of the atmosphere is reached. The logistic growth curve is S-shaped.

Thus,  The logistic population boost occurs when the growth rate of drops as the population reaches the carrying capacity.
