Question

how would describe the potato strip in saltwater? a firm and rigid b soft and flaccid question 5 how long did it take for the slowest diffusion to completely spread through the glass? blank 1 blank 1 add your answer question 6 what happened to the salt water potato after it was placed in the fresh water? a became soft and flaccid b became firm and rigid question 7 which glass solutions was hypotonic to the potato? a saltwater b freshwater

Explanation:

1. When a potato strip is in saltwater, water moves out of the potato cells by osmosis (from an area of lower solute concentration in the potato to an area of higher solute concentration in the saltwater), causing the cells to lose turgor pressure and become soft and flaccid. So for the first question, the answer is B.
2. For question 5, without any experimental data provided about the diffusion experiment, it's impossible to answer.
3. When a salt - water potato is placed in fresh water, water moves into the potato cells (because fresh water has a lower solute concentration compared to the salt - water potato cells), and the cells regain turgor pressure and become firm and rigid. So for question 6, the answer is B.
4. A hypotonic solution has a lower solute concentration compared to the potato cells. Freshwater has a lower solute concentration than potato cells, while saltwater has a higher solute concentration. So for question 7, the answer is B.

Answer:

1. B. soft and flaccid
2. No answer (lack of data)
3. B. became firm and rigid
4. B. Freshwater
