NOTES FROM MR.ANDERSON’S WATER POTENTIAL VIDEO (SAVES TIME AND EFFORT!) Water potential is the potential energy of water per unit area compared to pure water. Which allows you to figure out where water’s going to flow due to osmosis‚ gravity‚ pressure and even surface tension. It also allows you to figure out if water will flow in the first place and if it will flow into the cell or not. Water Potential (symbol psi) = Solute Potential (symbol psi s) + Pressure Potential (symbol psi p) Solute

it was not until my first test in AP Biology‚ that I realized I actually had to go the extra mile and put forth maximum effort into studying and reviewing. I needed a biology mentor like Mrs.Ciasulli to bring out the best in me because she knew of my aspirations to work in the medical field. Although she attempted to make my life as difficult as possible‚ she made me fall in love with the material and gain much more appreciation for the study of biology. AP Biology then became the class I was most

Ch 22‚ Q3: How did progressive ideals fare during wartime? The progressive ideals did not fare well during wartime; the only ideals that gained a victory were woman suffrage and prohibition. Women had made great progressive during the Progressive era and the war brought new opportunities for women. Over 25‚000 women served in France during the war (Roark 725). The biggest advancement in woman suffrage was when Congress passed the Nineteenth Amendment in 1919‚ which granted women the right to vote

Biology Unit 2 Module 2 1.1: Explain the uptake of ions by active transport in roots; * Emphasize the role of the endodermis. Most plants secure the water and minerals they need from their roots. The path taken is: soil -> roots -> stems -> leaves The minerals (e.g.‚ K+‚ Ca2+) travel dissolved in the water (often accompanied by various organic molecules supplied by root cells).Less than 1% of the water reaching the leaves is used in photosynthesis and plant growth. Most of it is
