Natalia Wierzchon A.P. Biology Lab: 1. Osmosis 09/10/2010 I. Introduction a. Purpose: The purpose of this lab was to observe the diffusion process of water‚ osmosis‚ as well as create an understanding of water potential‚ the basis of osmosis. The experiment proved how water molecules in a solution are able to move from an area of low solute concentration‚ high water concentration‚ to an area of high solute concentration‚ low water concentration‚ diffusing “down” the water gradient.

Reverse Osmosis Application Assignment Osmosis is the dissemination of water atoms through a semi-permeable layer from areas of high to low concentration in the direction that tends to equalize the solute concentration on both sides. In real life osmosis is found in roots of plants retain water from the dirt‚ and kidneys taking water from blood [5]. Reverse osmosis is the removal of solute from water by applying pressure to the water and moving the solution through a semi-permeable membrane. It is

was absorbed‚ whereas the length stayed the same. In Cylinder (B) the mass and length increased‚ which means the potato cells absorbed some Sodium Chloride (NaCl)‚ so the cells don’t shrivel up and die. For Cylinder 3 the mass and length also increased‚ like cylinder (B). The potato cells would have shrivelled up if water was released‚ so by absorbing more it avoided this. c.) The liquid that was…to the cell sap of the potato… i. Isotonic was NaCl (0.25M). The percentage change in length

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:

Tiffany Parker Mr. Taylor Biology 6th period 2/12/15 Gummy Bear Osmosis Lab Report Purpose: The purpose of this lab is to measure the amount of Osmosis in different types of solutions and to see how a cell would react in different types of solutions. Hypothesis: My hypothesis for this experiment is that the Gummy bear will absorb more of the plain tap and sugar water and the salt water will shrink the gummy Procedure: Materials- 3 clear cups‚ one spoon‚ 3 gummy bears‚ timer‚ tap water‚ salt‚ sugar

Advanced Placement Biology ® AP Biology Lab 1 281 EDVO-Kit # Storage: Principles & Practice of Diffusion & Osmosis Store entire experiment at room temperature. EXPERIMENT OBJECTIVE The objective of this experiment is to develop an understanding of the molecular basis of diffusion and osmosis and its physiological importance. Students will analyze how solute size and concentration affect diffusion across semi-permeable membranes and how these processes affect water potential. Students

Jordan Alyce Norris November 7‚ 2014 Biology 111-J3 Predicting Patterns of Inheritance Using Monohybrid and Dihybrid Crosses Introduction This experiment was on Mendelian Inheritance; which is the inheritance of biological features that are based on the rules proposed my Mendel. The purpose of this experiment was to show how to predict patterns of inheritance by using Punnett Squares to perform monohybrid and dihybrid crosses. Two crosses were performed. Cross one consisted of heterozygous alleles
