Once it had copied the DNA a cell normally divides into two new cells, this process is called mitosis each new cell gets a complete copy of all the DNA, bundled up as 46 chromosome. cells that are making eggs, or sperm cells they must be divide in a different way.
The answer is facilitated diffusion. Facilitated diffusion happens when there is a
carried changing the cell membrane so the nutrients can pass through. During facilitated diffusion, the absorbed
nutrients such as water soluble vitamins need a specific carrier to transport
the to the cell membrane.
Meiosis occur in the nuclear region of the cell, where all the cell's chromosomes are found.
As drosophila melanogaster is in eukaryotes so , the chromosome must be located in nucleus !
