Answer: 46 chromosomes
Explanation: Germ cells contain a complete set of 46 chromosomes (23 maternal chromosomes and 23 paternal chromosomes). By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. The overall process of meiosis produces four daughter cells from one single parent cell.
A solution that is:
Isotonic to the cell would cause no visual changes as the rate of water entering the cell is equal to the water exiting the cell.
Hypotonic to the cell would cause the cell to shrink, as water exits the cell to dilute the higher solute concentration outside the cell.
Hypotonic to the cell would cause the cell to swell, as water enters the cell to dilute the higher solute concentration inside the cell.
Is there a list to chose from or are you just looking for them all
