Which ions electrical charges oppose the direction of movement that is caused by their concentration gradient?
Any ion that is positive but has a higher concentration inside the cell or is negative and has a higher concentration outside the cell. Any ion that is positive but has a higher concentration inside the cell or is negative and has a higher concentration outside the cell.
What movement of gas molecules from a region of higher concentration to a region of lower concentration?
osmosis is the passive movement of a substance from a place where its concentration is higher, to another where its concentration is lower. This applies to gases, I guess
What is the movement of materials from a higher to a lower concentration?
Diffusion
What describes the movement of particles from higher concentration to lower concentration?
You think probable to diffusion.
When the concentration is higher on the outside of the cell it is?
Hypertonic solution.

What takes place during osmosis?
Osmosis is the movement of water form its higher concentration to lower concentration through a semi permeable membrane. In it water can move from inside to outside or outside to inside.
What is the movement from a higher concentration to a lower concentration?
Diffusion
What kind of environments causes water to enter or leave the cell?
Water Movement across a cell membrane is called Osmosis. And it is dependent on the concentration of ions on each side of the cell membrane. If the concentration is higher on the inside of the cell water rushes in to dilute the ion concentration and get it to equal the outside concentration of ions and this is called hypotonic. If the concentration is higher outside the cell water will rush out of the cell to help dilute the concentration outside the cell and get the two concentrations to become equal and is called hypertonic. If the concentration is equal in both outside and inside the cell there will be no water movement and is called isotonic. Osmosis

What is the direction of the water movement of animal cell?
Osmosis the the movement of water from where it is higher concentration to where it is in lower concentration.
What is diffusion and how does it relate to the movement of material into and out of the cell?
diffusion is the kinetic movement of molecules from higher concentration to lower concentration.
The inside of cells have a higher concentration of what?
The inside of cells have a higher concentration of Potassium. But there's a higher concentration of Sodium outside the cell.
Difusion is the movement of particles from an area of?
higher concentration to a area of lower concentration
What means from higher concentration to lower concentration?
Diffusion is the movement of particles from a region of higher concentration to a region of lower concentration. Osmosis is the diffusion of water molecules (only) from an area of higher concentration to an area of low concentration.
Why cell?
If placed in a hypertonic solution, cells will shrink because the solute concentration outside the cell will be higher than inside the cell. This causes the movement of water out of the cell (in order to equalise the concentration).
What is the movement of materials from a higher to a lower concentration?
Diffusion
