Egg-speriment Write-up Part 1- Purpose: Why did we do the experiment? The purpose of this experiment was to understand how osmosis works and that the cell membrane is selectively permeable. Osmosis is the diffusion of water molecules through a selectively permeable membrane. Many cells cannot function without adequate water‚ so cells depend on osmosis. When a cell is selectively permeable‚ it means some substances can pass through while others can’t. Many examples of these were shown throughout

waterBoiling chipProcedureA Separation of a Sodium Chloride and Charcoal Mixture#1 Place 4 g of the salt/charcoal mixture in a 100 mL beaker and add about 15 mL of distilled water. Stir the mixture for about two minutes to allow the salt to dissolve. #2 Set up a filter funnel with filter paper on a filter funnel stand. Filter the mixture and collect the filtrate in a 100 mL beaker as shown in Figure 1.1. #3 Wash the solid with a further 5 mL of water but do not add this to the filtrate. Note and record

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

September 18‚ 2011 Period 8 AP Bio Ms. Dahle September 12‚ 2011 TITLE: Population Genetics and Evolution Within a Gene Pool INTRODUCTION: The Hardy-Weinberg scheme is a way of viewing evolution as changes in the frequency of alleles in a population of organisms. If A and a are alleles for a particular gene and each individual has two alleles then p is the frequency of the A allele and q is the frequency of a alleles. The frequency of the possible diploid combinations is expressed in the equation

EXPERIMENT WRITE-UP INTRODUCTION: Information entering the memory can take on different forms‚ e.g. images‚ sounds or meaning. A way in which information is processed is through encoding‚ which is when information enters the sensory memory and is changed into a form that the memory can store it in. Information can be encoded as visual‚ acoustic or semantic. Evidence suggests that the primary encoding method for information to be stored in the short term memory (STM) is through acoustic coding

Introduction Genetics is the study of units of heredity. Genes determine almost everything about what makes humans humans and genes are passed from parent to offspring‚ because genes have a strong influence on all organisms. Genetics a very broad scientific discipline and the father of genetics is Gregor Mendel. Gregor Mendel studies how genes were inherited in pea plants by crossbreeding thousands of those and discovering their patterns and characteristics. In 20th century the technology has advanced
