If a cell failed to go through DNA replication prior to mitosis, what would be the resulting issue with the daughter cells?

• The daughter cells will be genetically identical to the parent cell.
• The daughter cells will have an incomplete set of chromosomes.
• The daughter cells will have double the number of chromosomes.
• The daughter cells will have an extra set of organelles.

• Has a lower concentration of solutes than the cell.

• Does not cause net movement of water into or out of the cell.

• Commonly found in freshwater environments.

• Maintains cell shape without causing swelling or shrinking.

• Facilitates the exchange of nutrients and waste.

• Can lead to crenation of cells.

• Causes a cell to shrink.

• Has an equal concentration of solutes compared to the cell.

• Essential for maintaining homeostasis in cells.

• Causes a cell to swell.

• Used in medical treatments for dehydration.

• Used in medical treatments to reduce swelling.

• Has a higher concentration of solutes than the cell.

• Promotes osmosis into the cell.

• Commonly found in seawater.

• Commonly used in IV fluids for hydration.

• Promotes osmosis out of the cell.

• Can lead to cell lysis if the influx of water is excessive.
