Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. During reproduction, when the sperm and egg unit to form single cell for sexual reproduction. During reproduction, when the sperm and egg unit to form a single cell, the number of chromosome is restored in the offspring.
Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome. The parent cell undergoes one round of DNA replication followed by two separate cycles of nuclear division. The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.

The correct answer is this one: "C) Nnew = Nold + 2." A student is studying a process in which a diploid cell becomes haploid. The CORRECT mathematical model for the process if Nnew is the number of chromosomes in the haploid cell and Nold is the number of chromosomes in the diploid cell is this: <span>new = Nold + 2
</span>
Here are the choices.
<span>A)
Nnew = 2·Nold
B)
Nnew =
Nold
2
C)
Nnew = Nold + 2
D)
Nnew = Nold × 2</span>
The possible answers are
1. Abiotic environmental
2.Biotic environmental
3.Genetic
<span>4.Pathogenic
</span>
The correct answer is 2.
There are two groups of environmental factors, the abiotic factors like temperature and biotic factors that refer to the effects that living beings have on each other.
<span>The flesh-eating bacteria, Vibrio vulnificus is a living organism affecting another organism by attacking its healthy flesh, therefore this effect is classified as a biotic environmental factor.</span>
