Question

What do you think having the cells at the same concentration as the environment would mean for the organisms in terms of osmosis and homeostasis?

the concentration of salt outside the cells is much higher, so water rushes out of cells, causing cells to shrink and homeostasis to be lost

since the concentration is the same on both sides of the cell, the net flow of water is zero, the cell's shape stays the same, and saltwater does not affect the organism's homeostasis

since the concentration is the same, no osmosis occurs and homeostasis is maintained

concentration of salt inside the cells is much higher, so water flows into cells, causing cells to swell and homeostasis to be disrupted

Answer 1

Same concentration means that there is an isotonic environment. Now, although isotonicity is great for cellular integrity it does not fully imply homeostasis in real life, but it seems like your question is designed in a way to only consider salinity. Anyhow, isotonicity means there is the same concentration on either side of the membrane so the water potential is 0, thus the net flow is zero and the cellular integrity is constant. This would narrow down B and C for you. What do you think?

Answer 2

c

Answer 3

Right?

Answer 4

I was heading for B because C seems a bit too extreme of an answer, no? We can't say that osmosis doesn't occur at all, but we can say that based on the given information, the net flow of water is constant and cellular integrity is preserved.

Answer 5

Oh I see thank you
