A scientist put red blood cells in water that contained salt. Over time, the red blood cells burst. What is most likely true?

The concentration of water inside the cell was greater than in the salt water.

There was a higher concentration of salt in the water than in the cells.

There was a lower concentration of salt in the water than in the cells.

The concentration of water in the cells and salt water were equal.

Gus is performing an experiment on cells. First he places the cells in a container of water and salt. When he checks some of the cells under a microscope, he sees that they are beginning to shrivel. What would most likely stop the cells in the liquid from shriveling?

adding more water to the container

adding more salt to the container

increasing the number of cells in the container

decreasing the number of cells in the container

Which statement describes how diffusion works?

Molecules always move from inside of the cell to outside of the cell.

Molecules always move from areas of high concentration to low concentration.

Molecules always move from areas of low concentration to high concentration.

Molecules always move from of outside the cell to inside of the cell.

Which statement describes the movement of water when a cell swells and bursts due to osmosis?

Water went into the cell because the concentration of water inside the cell was lower than the concentration outside the cell.

Water went out of the cell because the concentration of water inside the cell was higher than the concentration outside the cell.

The cell membrane used energy to move water into the cell because there was not enough water inside the cell

The cell membrane used energy to move water out of the cell because there was too much water inside the cell

Which process moves molecules and has these traits?–requires no energy–moves from high concentration to low concentration–moves from uneven distribution to even distribution–can occur when there is no membrane

scattering

diffusion

osmosis

dissolving

During an experiment, a student moves a cell from pure water to salted water. What will most likely happen to the cell?

It will release water and shrivel.

It will release water and burst.

It will take in water and shrivel.

It will take in water and burst.

The image on the left shows a normal red blood cell, and the image on the right shows a cell that has been put into a new solution. The circles represent the salt in the solutions.

The cell membrane uses energy to move water into the cell from low water concentration to high water concentration.

The water molecules move by osmosis into the cell from low water concentration to high water concentration.

The water molecules move by osmosis into the cell from high water concentration to low water concentration.

The cell membrane uses energy to move water out of the cell from low water concentration to high water concentration.
