Question
In diffusion, the NET movement of solutes goes according to the concentration gradient, or, from areas of concentration to areas of concentration Question 1 Not yet answered Marked out of 1.0 Select one a. High /Low b. all directions O c. High/ High d. Low /High Flag question Question 2 Not yet answered Marked out of 1.0 If a solute is permeable it is Select one O a. able to dissolve in water O b. able to pass through a membrane Flag question c. able to absorb water What determine the direction of solute movement? Question 3 Not yet answered Marked out of 1.0 Select one a. water Flag question b. the concentration gradient O c. membrane permeability d. the solventExplanation / Answer
1. a. High, low
Diffusion is the net movement of solute particles of from higher concentration to lower concentration.
2. b. pass through a membrane.
If a solute is permeable, then it can pass through a membrane.
3. b. the concentration gradient.
The direction of movement of a solute is determined by its concentration gradient. It moves from heigher concentration to lower concentration.
4. a. Inward
The sodium moves inward because the concentration is low inside. As the membrane is permeable to sodium, it moves inward.
5. c. neither
As the membrane is impermeable to sodium, it cannot move through there is concentration gradient.
6. a. The solute concentration, from high to low. Water goes toward the high solute concentration.
Water goes toward the high solute concentration, thus bringing equilibrium of solute on either side.
