It is the theory that states when a goat walks up to you and you pet it you are cursed for ever.
In an isotonic solution the shape of a cell remains unchanged. This is because the movement of water inside the cell equals the movement of water outside the cell.
This is called inertia.
Water moves towards a solution of greater concentration. If the solution is isotonic there will be no net movement.
Isotonic exercise (or muscle contraction) is when the muscle contracts and shortens giving movement (ie a bicep curl, lifting and lowering weight) Nearly all the training you do is Isotonic the opposite is Isometric, where the muscle contracts but des not shorten, giving no movement. Eg, Weightlifting, Lifting the weight up and down is isotonic Holding the weight still above the head is isometric
An activity that combines muscle contraction with repeated movement is Isotonic execrise
Isotonic solution.Common table salt when added to water is an example of a solute. For example, salt crystals (the solute) are the part of salt water (a solution) which has changed its state when added to water (the solvent).
There is no net movement of water molecules in and out of the cell.
Isotonic contractions are the type that involve muscle movement. This movement is due to a change in length as the muscle fibers shorten or lengthen.
The equal movement of molecules would be describing an "isotonic" state, where concentration gradients are equal, and a state of equilibrium is created.
Isotonic does not change the shape of a cell membrane
i think is the isotonic .. Diffusion is the spread of molecules. Osmosis is the movement across water.
