Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

Title- Mitosis Abstract –For this lab there is no experiment to be done only questions to be answered. In this experiment we will categorize and count the cells to compute the mitotic index of the total root area. Introduction – The purpose of this experiment is to answer questions associated with the onion root tip photos that are pictured in the lab. The questions for this lab will be drawn from the discussion and review section at the beginning of the mitosis lab. Once that section has been reviewed

of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal

indicated by a very pale pink color. To calculate the molarity of NaOH‚ the following equation was used MNaOH x VNaOH = MKHP x VKHP therefore the molarity was .125 M. INTRODUCTION This lab experiment covers the preparation of standard solution and the acid/base titration. The first part of the lab is to prepare a standard solution of Potassium hydrogen per. A standard solution is a solution of known concentration‚ in which it is prepared using exacting techniques to make sure that the molarity

Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

The gametes that are produced by meiosis in humans are haploid‚ containing only one copy of each of the twenty-three chromosomes. Because of recombination and independent assortment of parental chromosomes‚ the daughter cells produced by meiosis are not genetically
