MEMO To: Carrie Johnson From: Staff Biologist RE: Bacteria The first step in identifying the mystery organism is to know what kingdom it belongs to. It will belong to one of the following kingdoms: animals, plants, archaebacteria, eubacteria, fungi, or protista. Organisms are placed into these categories based on similarities or common characteristics. Some of the characteristics that are used to determine placement are cell type, metabolism, and reproduction. Examine your living organism and determine if it is a bacteria, achaean or a eukaryote.
The streak plate technique is done to isolate a colony formed by a single cell from a mixture containing millions of cells. The streak plate technique was also used to obtain pure cultures of the bacteria using a trypticase soy agar (TSA) plate and was incubated at 37 ̊ for 48 hours. Secondly a Gram stain was performed as directed from exercise 6in the lab manual (Kleyn 37) and was found to be Gram negative Rods. The Gram stain is important to do because it reveals the morphology of the organism and the arrangement of the cells; if an organism appears purple under a microscope then it is said to be Gram positive, and if it

Genetic introgression and the survival of Florida panther kittens. Web: journal homepage: www.elsevier.com/ locate/biocon The book is an in-depth study of the Florida panther kittens. It tracks their breeding and show the advantages of cross breeding so as to maintain the robustness of the species. 3.
Hybridization- crossing different traits to bring the best of organisms into one. For example crossing disease resistance of one plant with the food-producing capacity of another to produce a superior plant. 3)Cloning is the process of taking a single cell from an adult organism to recreate another genetically identical organism. 4)DNA fingerprinting is developed by molecular biology; it analyzes unique sections made up of a variety of DNA band. DNA fingerprinting is a powerful and crucial tool that can determine a person’s identity.
What did Gregor Mendel contribute to the study of biology and what 7 plant traits did he study? Gregor Mendel was the first person to comprehend some of the most basic principles of genetics, and use his experimental subject a species of garden pea. He looked at 7 characters in his plants such attributes as seed color and texture. In his plants, each of these characters came in two verities or traits, one of them dominant and the other recessive. Flower color or purple or white.
Follow the directions below to collect the required data then use that data to answer the discussion questions that follow. Experiment 1: In this experiment you will be examining the effect of a mutation that changes the color of the organism and alters how it avoids predators. Before you start: Read through the experiment. Then in the space below hypothesize how this change in DNA will affect the evolution of this population over the next 10 generations.

Biochemistry Article Review The Proof Is in the Proteins By: Katherine Harmon My article The Proof Is in the Proteins outlines how Douglas Theobald an assistant professor of biochemistry of Brandeis University took the idea of there being a single ancestor to all other organisms and proved this old-age Darwinian theories likelihood. This theory comes from Charles Darwin who fathered the theory that all species of life came from one common ancestor evolving over a period of time. This theory is one that many researchers and biologists base there own work around. Many people think it may already be obvious that many life forms grew from one single organism because of the fact that we have discovered and dissected DNA and its genetic heritage. With the discovery of DNA in the mid-20th century it established this idea in popular and academic rings
