Difference between osmosis, diffusion and plasmolysis
pickupchik [31]
Osmosis is the movement of water particles from an area of high concentration of water particles to an area of low concentration of water particles across a semi permeable membrane

Diffusion is the movement of particles from an area of high concentration of particles to an area of low concentration of particles across a partially permeable membrane

Plasmolysis is the shrinking of the cytoplasm if a plant cell in response to diffusion of water out of the cell and into a high salt concentration solution as the cell membrane would pull away from the cell wall

Answer:

I would say B is the answer.

Explanation:

An applied force is a force that is applied to an object by a person or another object. Example: pushing a box to the other side of a room.

A normal force is a force that surfaces exert to prevent solid objects from passing through each other. Example: resting a book upon a table.

Drag is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This doesn't really match the force we use.

However, an attractive force is a force by which one object attracts another. Example: two magnets pulling/colliding together. This is a good example of a force we exert on objects when it is pulled toward us.
