Answer:
C. It would increase.
Explanation:
Increase in concentration of carbon dioxide results in high hydrogen ion concentration in the blood or ocean increases the pH and decreases the ability of hemoglobin to bind with oxygen.
<u>An increase in pH leads to the acidity of the blood that stimulated brain cells to produce faster and deeper breathing to compensate for the shortage of oxygen in the body.</u>
Hence, the correct answer is "C. It would increase".
Osmosis is the net movement of water molecules through a semi-permeable memberane from a region of higher water potential to a region of lower water potential.
so in the first case, since 10% of sucrose solution has a lower water potential than the pure water, so water molecules will flow into the sac, causing the sac to increase in volume. note that sucrose molecules can't diffuse out since there's a semi-permeable membrane.
in the question, I'm not 100% sure what the "sac solution" is meant by, but I guess it's the solution inside the sac
so here if the sac sucrose is 20%, the concentration of water is larger in difference than the first time, so osmosis rate will increase.
but if the "sac solution" is meant by replacing the water of the first case, then the sac inside would have a higher water potential, as the sucrose concentration is more diluted. then the water molecules will flow from the sac back to the beaker or whatever container it is.
