Hypotonic
This picture shows molecules of red dye that have moved. What is this type of movement called?
Osmosis; the water molecules are moving from high concentration to low
Diffusion; the dye molecules are moving from low to high concentration
Diffusion; the dye molecules are moving from high to low concentration.
Facilitated diffusion; because the molecules are moving through a protein channel.
The cell membrane needs to use energy to move molecules quickly out of the cell through a pump. What type of transport is this?
Passive transport
Active transport
Active transport is when molecules move ________ the concentration gradient.
against
up
down
with
This picture is a representation of what type of transport?
Osmosis because it is diffusing through a protein from an area of high concentration to low concentration.
Facilitated diffusion because it is diffusing through a protein from an area of high concentration to low concentration.
Facilitated diffusion because it is diffusing through a protein from an area of low concentration to high concentration.
Simple diffusion because it is diffusing through a protein from an area of high concentration to low concentration.
This picture describes the movement of molecules across the cell membrane. Choose 2 answers that correctly describes the movement of the molecules.

A cell with a 10% salt solution; is placed in distilled water with 0% starch concentration. Water can travel across a semipermeable membrane but starch cannot. Would you expect to see after an hour?
The solution inside the cell is hypotonic and moves into the cell.
The solution inside the cell is hypertonic so the water moves into the cell.
The solution inside the cell is hypotonic and moves out of the cell.
The solution inside the cell is isotonic so the water doesn't move.

Elige las imágenes (3) que representan el transporte ACTIVO.
The picture shows a prokaryotic freshwater organism in water, what would cause its vacuole to become filled with fresh water?
¿Qué haría que su vacuola contráctil se llenara de agua?
the temperature of the water in the vacuole is higher that the temp of the water out of the vacuole
the concentration in and out of the cell is the same
the concentration of water is higher out of the cell than in
the temperature of the water in the vacuole is lower that the temp of the water out of the vacuole
15. A person with swollen gums rinses his mouth with warm salt water, and the swelling decreases. Which of the following has occurred?
A. The swollen gums have absorbed the saltwater solution.
B. The saltwater solution lowers the temperature of the water in the gums.
C. The salt in the solution has moved against the concentration gradient.
D. The water in the gums has moved out due to the high concentration of salt in the solution.
