In this activity, the solutes were transported through the dialysis membrane by _______. simple diffusion active transport osmosis facilitated diffusion

Through which membrane(s) would sodium chloride diffuse? 200 MWCO only 20 MWCO, 50 MWCO, 100 MWCO, and 200 MWCO 100 MWCO and 200 MWCO 50 MWCO, 100 MWCO, and 200 MWCO

Which of the following generated osmotic pressure? sodium chloride, glucose and albumin generated osmotic pressure. albumin glucose sodium chloride

Which of the following would result in NO change in osmotic pressure across a membrane? Water is moving with its concentration gradient. The solutes can diffuse through the pores and the concentration of solutes is the same on both sides of the membrane. The solutes can diffuse through the pores. The concentration of solutes is the same on both sides of the membrane.

The net movement of water is away from the albumin. Albumin and glucose diffuse through the membrane. The net movement of water is toward the albumin.

If the intracellular concentration is 10 mM and the solution is 20 mM, which of the following is true? The net movement of water is into the cell. The solution is hypotonic. The cell will shrink. There is no net change in the movement of water into the cell.

Which of the following resulted in an increase in the filtration rate? increasing the pressure above the beaker Both increasing the pore size and increasing the pressure above the beaker are correct. increasing the pore size increasing the concentration of the solutes Both increasing the pressure above the beaker and increasing the concentration of solutes are correct.

Which solute did NOT appear in the filtrate using the 200 MWCO membrane? Glucose, charcoal, sodium chloride and urea appeared in the filtrate. urea sodium chloride charcoal glucose

Which of the following was NOT observed during this activity? Some solutes were too large to pass through the membrane. The 200 MWCO membrane was the largest pore size used. A residue of solutes remained on the membrane after filtration. Increasing the rate of filtration increased the concentration of solutes in the filtrate.

Increasing the pressure above the beaker is analogous to _______. an increase in blood pressure a decrease in blood volume an increase in heart rate an increase in solutes found in the blood
