Roy Levin Bio 11 Lab Dr.Izquierdo Analysis of Macromolecules in Tissue Homogenates of Bos taurusMaterials and Methods The homogenates provided were made by homogenizing tissues in a sucrose phosphate buffer in a 1:20 ratio. The protein concentration in bovine cells was measured by diluting the homogenate with a 1:5 ratio; 50 microliters of homogenate and 200 microliters of water. Then 5 known protein concentration samples which were 0.4‚ 0.8‚ 1.2‚ 1.6‚ 2.0 mg/ml of bovine serum were used to

Meiosis and Mitosis Meiosis vs. Mitosis: Meiosis requires two nuclear divisions‚ but mitosis requires only one nuclear division. Meiosis producers four daughter nuclei‚ and there are four daughter cells following cytokinesis; mitosis followed by cytokinesis results in two daughter cells. Following meiosis‚ the four daughter cells are haploid and have half the chromosome number as the parent cell. Following mitosis‚ the daughter cells have the same chromosome number as the parent cell. Following

LAB REPORT Introduction: In a chemical change‚ the identities of substances change and new substances form. In an equation the substances on the left are the reactants. The substances on the right are the products. In this experiment the objectives are to observe evidence that a chemical change has taken place. Infer from observations that a new substance has been formed. Identify and record observations that show energy is involved in chemical change observe the color‚ solubility of some substances

Growth‚ repair and reproduction. • Growth: This is a result of mitosis. The more cells in an organism‚ the larger that organism is. Humans start off as one single cell‚ and by the time they are adults‚ they have over 10 trillion cells!!! This increase in the number of cells also allows for some of those cells to be specialized for various functions. This is important to the survival of many organisms. • Repair: This is a result of mitosis. If tissue is damaged‚ repair is extremely important. With

Observation of Mitosis Introduction: Reproduction is the biological process by which new individual organisms are produced. There are two types of reproduction‚ which are; asexual and sexual reproduction. Asexual reproduction is creation of offspring whose genes all come from one parent. Sexual reproduction is creation of offspring by fusion of male gametes (sperm) and female gametes (eggs) to form zygotes. Asexual reproduction involves a type of cell division known as mitosis. Mitosis is the scientific

Biology Lab Report 7 “Independent Assortment & Dihybrid Cross” 10-22-2013 Biology 202 Introduction: In genetics‚ when crossing a purebred white flower with a purple flower‚ we might expect its offspring to be a blend of both colors. Instead‚ we see that its offspring is purple as well. This is led to be by one trait being dominant over another trait. Gregor Mendel came up with a theory that each member of a pair of homologous chromosomes separates independently
