Which of the following best describes what is happening in the image above?
Diffusion is causing particles to move from an area of high concentration to an area of low concentration
Osmosis is causing water to move from an area of low concentration to an area of high concentration
Diffusion is causing particles to move from an area of low concentration to an area of high concentration
Osmosis is causing water to move from an area of high concentration to an area of low concentration

What will happen to the cell in the beaker?
Particles will move from the solution into the cell through the cell membrane
Water will move from the cell into the solution through the cell membrane
Particles will move from the cell into the solution through the cell membrane
Water will move from the solution into the cell through the cell membrane
30s - Q4
Particles move into the cell until there are an equal number of particles on the inside and outside of the cell
The cell creates new particles that stay inside of the cell and are carried to the ribosome
Particles cannot move into or out of the cell, causing waste to build up within the cell
Particles move out of the cell toward an area of low concentration until there are more particles outside of the cell
30s - Q5
Your friend has a new pet snail. She read online that pouring salt over a snail could be bad for the snail. Which of the following responses best explains why pouring salt over the pet snail is a bad idea?
The salt will cause water to flood the snail's cells, eventually causing the snail to swell up
The salt will enter the snail's cells and interfere with important cell processes, such as protein production
The salt will leave the snail's cells, causing it to shrink up and become very dehydrated and weak
The salt will cause water to leave the snail's cells, dehydrating the snail and possibly killing it
