This document provides an overview of general physiology and cell physiology concepts. It discusses homeostasis and how the body maintains stable internal conditions through negative feedback loops. Key organelles like the mitochondria, Golgi complex, endoplasmic reticulum, lysosomes, and nucleus are described. The structure and function of the plasma membrane, including the fluid mosaic model, transport proteins, and passive transport mechanisms like diffusion and facilitated diffusion are also summarized.

98. SURFACE TENSION IS THE TENDENCY FOR A LIQUID TO CONTRACT AS A CONSEQUENCE OF ITS POSSESION OF FREE ENERGY, SINCE APPROACH TO EQUILIBRIUM IS ALWAYS ACCOMPANIED BY A DIMINUTION OF FREE ENERGY . We’ve all played with it- water drops being added one at a time, until that one drop breaks the surface and the water spills out.

99. IT IS HARD TO BELIEVE THAT H-BONDS AND SURFACE TENSION ARE ENOUGH TO KEEP THE VOLUME OF WATER THAT IS IN THESE BEADS STUCK TO THE PLANT
