Physiology I got to take part in dissecting a cow eye. My lab partner was . The purpose of dissecting the cow eye was to learn and familiarize the class with the structure of the eye and to locate structures. Materials used were the cow eye‚ scalpel‚ probe‚ tweezers‚ scissors‚ dissection tray‚ gloves‚ paperwork / book‚ paper towel‚ ourselves‚ and our lab partner. My data includes the checklist‚ lab sheets‚ drawing‚ picture‚ and my lab report. The first step was to observe the outer structure

Tim Readmond AP Biology Lab Report I. Title a. Modeling Diffusion and Osmosis II. Introduction a. If one places a 1.0 M solution of glucose inside a bag and then places that bag into a beaker containing a 1.0 M solution of sucrose‚ the percent of mass lost in the bag is 10.5%. The solution in the bag is hypertonic while the solution in the beaker is hypertonic‚ which is why water moves from the bag to the beaker and the bag loses mass. b. The purpose of this experiment is to see whether

AP Biology 6th Mr.Scofield Blast Lab Background: Between 1990–2003‚ scientists working on an international research project known as the Human Genome Project were able to identify and map the 20‚000–25‚000 genes that define a human being. The project also successfully mapped the genomes of other species‚ including the fruit fly‚ mouse‚ and Escherichia coli. The location and complete sequence of the genes in each of these species are available for anyone in the world

PHOTOSYNTHESIS LAB Alyssa Wright VARIABLE: LIGHT INTENSITY AIM: to investigate the effect of light intensity (lux) on the amount of oxygen produced (number of bubbles) HYPOTHESIS: I predict that the rate of oxygen produced increases‚ as the light intensity increases‚ but only to a point. I predict this will happen because the plant will have enough carbon dioxide and water to keep up with the amount of light that there is. When there is less light intensity‚ photosynthesis will happen

MACROMOLECULS LAB: What are the mystery powders? Period: 4 Asia Enoch Introduction: A carbohydrate is an immediate form of energy in your body. Monomers is smaller than a polymer. For carbohydrate the monomer is sugar and the polymer is a polysaccharides. Carbohydrates are important to our body because we need to use energy. The purpose of this lab is to figure which one is the monomer and which one is the polymer. Hypothesis: If I place two drops of iodine into the mystery powder‚ it

Introduction The purpose of this lab was to test different antacids‚ to find out which would be the most effective to take. Stomach acid problems come from a overproduction‚ and build up of gastric acid (HCl). In order to determine which antacid is the more effective‚ four different brands of antacids were chosen‚ and tested. The purpose of an antacid is to balance out the pH inside a person’s stomach. PH is the measurement of molar concentration of hydrogen ions that are present in the solution

The purpose of this lab was to see which solutions are soluble and which are not. We were able to see this by mixing certain solutions together and observing changes that occurred. The procedure for this experiment included a few different steps. The first steps were to add the nitrate solutions into the lettered parts of the 96-well plate. Once you were done with that‚ you were supposed to add the sodium solutions to the numbered parts of the 96-well plate‚ so that the solutions were added together

Tyler Cowan Professor Foltz Biology 181 April 8th 2015 Lab Report: Respiration Abstract: The objective of this lab was to figure out which has a higher cell respiration rate between crayfish and elodea. In order to figure this out we first set up three beakers to represent our control‚ elodea and crayfish and filled them with 75mL of culture solution which were dechlorinated making the solution acidic. We then had to place both the elodea and the crayfish in separate beakers filled with 25mL of
