One purpose of the experiment was to gain an understanding of diffusion and osmosis‚ specifically in context of a plant or animal cell reaction to an isotonic‚ hypotonic‚ or hypertonic solution. Another objective was to understand the nuances of simple diffusion‚ facilitated diffusion‚ and active transport and to explicate the characteristics affecting the rates of diffusion. The next objective was to be able to explicate the partition coefficient and its influence on hemolysis. The final objective

Plant Genetics JANICE NALBONE Abstract This experiment is being done to show Mendel’s rule of dominance that says certain alleles are dominant and others are recessive. To show this‚ we are using tobacco seeds‚ a monohybrid cross comparing only one trait color. We are also showing Mendel’s law of segregation with a Dihybrid cross comparing two traits of color and texture. Introduction

My First Lab Report: Diffusion and Osmosis To begin‚ this is my first time doing an experiment and a lab report for biology’s class. Although‚ it was a little hard at the beginning‚ my team and I got the hang of it and we finished it on time. It was actually kind of fun. There were three steps in the experiment: 3.1 A – Molecular Movement: In this session‚ I was observing a sample and determining if there was a movement or not. 3.1B –Diffusion through semi-permeable membrane dialysis tube: In this

The Rate of Diffusion in Different Temperatures Purpose: To see if the temperature of a solution will change the rate blue diffuses in it. This will be tested by timing how long it takes dye to diffuse in warm water‚ cold water‚ and room temperature water. Hypothesis: I think that the dye will diffuse at a faster rate in the warm water than in the cold water. I believe that the room temperature water will have the dye diffuse faster than the cold water but slower than the warm water. Variable:

and Diffusion Lab Report Background Information: Diffusion involves the movement of solute particles across a selectively permeable membrane from higher to lower concentrations. A selectively permeable membrane allows only some thing to go through. Water and oxygen are examples of molecules that are able to go through the membrane by diffusion. The

Austin Vandermey GS-1140 April 4th‚ 2015 Experiment We as a society have one big problem on our hands. This problem is sleep deprivation because there are not enough hours in the day to get stuff done. Between work‚ school‚ family‚ and leisure it seems like we do not have enough time to get are daily tasks done let alone have time for sleep. It is recommended by the U.S Department of Health that people need a solid eight hours of sleep to maintain good health. I don’t know about you

Experiment #1: Introduction to Experimentation Submitted by: Neann Klara M. De Jesus BS Psychology II Submitted to: Dr. Geraldine E. Tria ABSTRACT SUMMARY The first experiment done by the class was called “Introduction to Experimentation”. Its main objective is to give basic knowledge about some of the logic of experimentation. The class was divided into groups of 2. In each group there was an experimenter (E) and a subject (S). The experimenter instructed

Biology Project Autumn Brown 3rd block Mrs. Stephens More than 2‚000 years ago‚ Aristotle began grouping plants and animals into various categories. Although he did not consider the idea that different organisms were related by descent‚ he devised a system that placed these organisms in a hierarchy. Through classification systems‚ scientist have found it easier to find answers to important questions. This way
