Question

scenario 3: a lab technician is conducting an experiment to observe the effects of different solutions on red blood cells. the technician prepares three slides, each with a drop of blood mixed with a different solution. the observations are as follows: based on the observations, what type of solution was used on slide 1, and what process caused the cells to swell and burst? a hypertonic solution; the cells lost water through osmosis a hypotonic solution; the cells actively pumped in excess water an isotonic solution; water moved in and out of the cells equally a hypotonic solution; water moved into the cells through osmosis

Explanation:

In a hypotonic solution, the solute concentration outside the cell is lower than inside. Water moves into the cell by osmosis to equalize the concentration, causing the cell to swell and burst. This is consistent with the description of cells swelling and bursting on Slide 1. Water movement in cells occurs through osmosis, not active pumping in this context. In an isotonic solution, there is no net movement of water, and in a hypertonic solution, water moves out of the cell causing it to shrink.

Answer:

D. A hypotonic solution; water moved into the cells through osmosis
