    Absorption Spectrum of Pigments

    Compare and contrast the absorption spectrum of pigments of Cyanobacterium vs. the various purple bacteria. What wavelengths are preferentially absorbed by the pigments of each group of bacteria & how do the absorption properties of these molecules compare with the regions of the spectrum visible to our eye? How do they explain

    Growth rate of phototrophic purple bacterium Rhodobacter

    The growth rate of phototrophic purple bacterium Rhodobacter is twice as fast when the organism is grown phototrophically in a medium with malate as a carbon source as when it is growth with CO2 as a carbon source (with H2 as electron donor). Discuss reasons why and list the nutritional class of Rhobacter when growing under each

    Effects of Iodine on Glands in Endocrine System

    When reactor 4 at the Chernobyl Nuclear Power Station in Ukraine exploded on April 26, 1986, a great plume of radioactive isotopes erupted into the air and spread for thousands of miles. Most of the isotopes emitted after the blast were of the element iodine. Which of the glands of the endocrine system would be most seriously af

    Calculating Bacterial Numbers in Culture

    Starting with 4 bacterial cells per milliliter in a rich nutrient medium, with a 1 hour lag phase and a 20 minute generation time, how many cells will there be in 1 liter of this culture after 1 hour? After 2 hours?

    Specificity of Rhizobium

    All I can think of is inoculating lots of different types of plant seedlings with the bacteria and comparing their growth with uninoculated seedlings. As the specificity of Rhizobia-plant interactions is dependant upon genes is there some molecular or genomic way of analysing this? any help at all would be appreciated -

    The Digestive System: How It Works

    Imagine that you have been asked to provide an explanation about the structure and function of this system to the general public, perhaps a group of senior citizens who want to learn more about normal functions of the human body as well as health concerns. You will be providing the seniors with an informative handout. In th

    Genetics - Human Blood Types

    Part 1: Genetics Problem- Human Blood Types Mendel is the father of modern genetics, but there are some genetic characteristics that cannot be explained by simple Mendelian genetics. Such is the case with the human blood types in which there are 3 alleles for the same gene, A B, and o. A parent can pass allele A, B, or o to
