Summer Assignment – AP Biology – Chapters 2-5 Chapter 2 1. CHNOPS are the six most crucial elements in most macromolecules. Name them. Carbon‚ Hydrogen‚ Nitrogen‚ Oxygen‚ Phosphorous‚ Sulfur. 2. Create a chart and state how many bonds each of the CHNOPS elements can form. Carbon | Hydrogen | Nitrogen | Oxygen | Phosphorous | Sulfur | 4 | 1 | 3 | 2 | 3 or 5 | 2 | 3. Create a Venn Diagram to compare and contrast polar covalent bonds‚ nonpolar covalent bonds‚ and ionic bonds.

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:

Chapter 29 An Overview of Land Plant Evolution 1. Describe four shared derived homologies that link charophyceans and land plants. a. The complexes that produce cellulose are rose shaped in both charophyceans and land plants. Next both have peroxisome enzymes that help minimize the loss of organic products from photorespiration. The structure of their flagellated sperm is very similar. Finally‚ both form a phragmoplast during cell division. 2. Distinguish among the kingdoms Plantae‚ Streptophyta

AP Biology Lab 1 Ross Lordo Introduction Questions 1. The solute potential would be -2.48. If the concentration inside the cell is .15 M‚ then would diffusion out of the cell and into the solution of .1 M. This is due to water potential and the tendency for water to move from areas of high water potential to low water potential. 2. The turgor pressure must be equal to the water potential if there is no net diffusion. The cell and environment have reached equilibrium and the movement of water

Emad Abid Dr. Fuller AP Biology 13 August 2014 Animal Behavior of Isopods 1a) Do terrestrial isopods prefer to stay in a cold or warm environment that is in a neutral (room temperature)‚ mild‚ or extreme temperature difference from room temperature? 1b) If the isopods prefer to be in a mildly warm environment‚ then when they are randomly placed between a warm and cool chamber with only one warm and cold pack (mild temperature difference) on each end of the chamber and are able to move freely‚ they

Diffusion and Osmosis Through Dialysis tubing We did this experiment to test the diffusion of different substances through dialysis tubing. We used what we knew about diffusion to make predictions on what we thought the mass of the dialysis tubing to be after submerging them for 30 mins and we knew that diffuse occurs from highest concentration to lowest concentration. Since the dialysis tubings are filled with different substances than what they are being put into then they should all gain
