Metabolism: Discuss the need for a balanced diet. Why is it important? What is the importance of osmosis in the life of fresh water organisms? What is the benefit of a life cycle with two or more forms? Why can't fish breathe outside of water?
Why is diffusion important to cells? Moving Molecules: If you've ever sprayed an air freshener, lit a scented candle, or made a glass of Kool-Aid, you've experienced diffusion in action. This process of moving molecules from high concentration to low concentration is all around us. It is...
Bottom leaves turn yellow –Yellow leaves tend to appear toward the bottom of the plant Yellow leaves fall on their own –With a nitrogen deficiency, yellow leaves feel soft and are easily pulled off (in fact they usually fall on their own). If a leaf feels very stiff or is hard to pu...
