1. How do substances like CO2 and water move in and out of the cell? Explain.

The substances like CO2 and water move in and out of a cell by diffusion from the region of high concentration to low concentration. ... When the concentration outside the cell becomes low and it is high inside the cell, they moves out.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
