AP Biology August 23‚ 2012 Egg Osmosis Lab Definition of osmosis: The diffusion of water across a selectively permeable membrane from high to low concentrations Hypothesis: If I place an egg in vinegar‚ then the outer layer of the egg is going to become slimy and look like rubber. It will also become larger and bubbles will form on and around the egg. Hypothesis: If I place an egg in corn syrup‚ then the egg will become small and the outer layer will not look like rubber any longer. Day one:

AP Biology notes: Chapter 2- The Chemical Context of Life 1. Overview * The bombardier beetle fights the ants that plague it by using chemistry. * The natural systems and environment that organisms live in involves chemistry and physics. * Biology is not the only category of science. There is also chemistry‚ physics‚ and engineering. * Organization of life is separated into a hierarchy of structural levels. 2. Elements and Compounds * Matter- anything that takes up

BIOLOGY UNIT 2 – STUDY GUIDE CHAPTER 1: Environmental Factors and adaptions; 13.1 Note: Living organisms can survive‚ grow and reproduce only in surroundings that provide sufficient levels of nutrients‚ water‚ oxygen and carbon dioxide‚ and suitable living conditions such as light and temperature. Tolerance range: the range of conditions – for example‚ temperature that an organism can survive in. Tolerance range also affects the distribution of an organism meaning where they live. To
