a. Define diffusion. Is diffusion a passive or an active process? Explain how solute moves in this way. b. Use your knowledge of diffusion to explain what happened over time when you observed a crystal of methylene blue dropped into a beaker of water. Be sure to use equilibrium in your explanation. c. Explain your observations over time after a drop of methylene blue and a drop of potassium permanganate were placed in the agar. What factors affect the rate of diffusion? d. What are tissues? Name the four major types of tissues in the human body.   e. Name the three primary germ layers. Name the primary germ layers from which epithelial tissues and connective tissues develop.   f.
