ANATOMY

Detailed explanation-1: -Process of maintaining a constant internal environment is known as homeostasis.

Detailed explanation-2: -Cells isotonic to their surrounding solutions have an equal concentration of solutes in and out of the cell membrane. This creates a dynamic equilibrium that maintains the status of the cell. All living organisms must have a way to regulate their internal environments. This is called homeostasis.

Detailed explanation-3: -Solutions that contain the same concentration of water and solutes as the cell cytoplasm are called isotonic solutions. Cells placed in an isotonic solution will neither shrink nor swell since there is no net gain or loss of water.

Detailed explanation-4: -When a red blood cell is placed in an isotonic solution, there will be no net movement of water. Both the concentration of solute and water are equal both intracellularly and extracellularly; therefore, there will be no net movement of water towards the solution or the cell.

Detailed explanation-5: -Definition: Any process involved in the maintenance of an internal steady state at the level of the cell.
