How does molecules at point a compare to the molecules at point b

due to this there will be movement in the molecules of water. as a result, more heat is provided to them farther away they tend to move from each other. so, molecules at point b are farther away from molecules at point a. this means that these molecules have gained energy due to which they are moving at a faster rate.

several tissues working together form an organ, and several organs together make up an organisms.
