Bacterial adhesion to a material surface can be described as a two-phase process including an initial instantaneous and reversible physical phase phase one and a time-dependent and irreversible molecular and cellular phase phase two.
Adhesion is the tendency of dissimilar particles or surfaces to cling to one another. Adhesion is usually caused by interactions between the molecules of the two substances. C muscle is damaged.

Which of the following best describes what causes water molecules to exhibit properties such as cohesive and adhesive behavior. Water molecules are polar having partially positive and partially negative ends. One example of adhesion is water climbing up a paper towel that has been dipped into a glass of water and one example of cohesion is rain falling as drops from the sky.
