Genetics: the science of heredity that includes the study of what genes are‚ how they carry info‚ how they are replicated and passed to subsequent generations of cells or passed between organisms‚ and how the expression of their info within an organism determines the particular characteristics of that organism. Genome: the cell’s genetic information that includes it’s plasmids and chromosome. Chromosomes: structures containing DNA that physically carry hereditary info‚ contain the genes Genes:

READING MATERIAL 1. Explain the three hypotheses for the recent changes in the toxicity of venom in different species of rattlesnakes found in the United States. - Interbreeding between snakes with different venom profiles. - Geographic distribution (genes shifted eastward) - Convolution - Old rattlesnakes have high concentration of toxic. 2. What is an “evolutionary arms race”? Describe how this applies to one of the hypotheses suggested to explain toxicity of venom in rattlers

Lab 4: Fungi Non-filamentous forms — Single-celled Yeasts Do an Internet search for a microscopic image of baker’s yeast‚ Saccharomyces cerevisiae (Ascomycota). Answer the following questions: 1. Do the yeast cells have a definite shape or is there considerable variation? Yeast cells seem to vary in shape‚ some look to be more oval and round‚ although. some slides did show pear and cylinder shapes. 2. Can you detect any subcellular structure? I cannot detect a clearly visible

containing two copper atoms that reversibly bind a single oxygen molecule (O2). Oxygenation causes a color change between the colorless deoxygenated form and the blue oxygenated form. Hemocyanins carry oxygen in the hemolymph of most molluscs‚ and some arthropods‚ including the horseshoe crab‚ Limulus polyphemus. They are second only to hemoglobin in frequency of use as an oxygen transport molecule. Unlike the hemoglobin in red blood cells found in vertebrates‚ hemocyanins are not bound to blood cells but
