An isotonic solution is when the solute concentration is balanced with the concentration inside the cell , the water movement still moves between the solution, but the rates are the same in both directions, the water is balanced inside and outside the cell .
A hypotonic solution is when the solute concentration is lower than the concentration inside the cell. water moves into the cell and can cause the cell to swell; cells that don’t have a cell wall, such as animal cells, could explode in this type of solution.
A hypertonic solution is when the solute concentration is higher than the concentration inside the cell. In a hypertonic solution, the water moves out of the cell and causes the cell to shrivel.
Answer: cell wall, cell membrane, cytoplasm
Explanation:
Meningitis is the inflammation of the meninges covering the brain and spinal cord. One of the physical symptom is Kernig's sign. It is done by letting the person to lie flat and flexing the thigh and hip to 90 degrees. If the leg cannot be straighten then it means it is a neurologic positive sign for Meningitis.
A solution in which the salt concentration is higher outside the cell than the salt concentration inside the cell is called hypertonic solution this is the one that the concentration of solutes is greater outside the cell than inside.
