Virtual Lab Unit 3 1. Briefly describe the steps required to aseptically transfer bacteria from an unknown to a tube of liquid broth. You might have to research this using the "T" button (Tell Me More About...) To aseptically transfer bacteria from an unknown to a tube of liquid broth you have to flame the loop or wire before you begin to sterilize it. You then remove the caps from the tubes and flame the mouths of the tubes to prevent air-borne contamination. When all this is done‚ you have to

biological systems. Some species are able to survive in diverse environment such as fishes in salt water‚ Cactus plants in dry land and mammalian cells in aqueous surrounding because 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

Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

MICRO ENVIRONMENT/ INDUSTRY ANALYSIS The environment which is close to business and affects its capacity to work is called micro or operational environment. Industry is a group of companies which offer same or similar product or services. These products and services are close substitutes of each other. It consists of: 1 Suppliers Supplier are the people who supply raw materials and required components to the companies. Increasing prices and reducing the quality of their products are potential

- tall or dwarf peas. These seeds can be used to demonstrate the effect of the environment on the final height of the pea plants. Tall or dwarf peas can be grown in identical conditions where all variables are kept constant apart from one environmental factor. Any differences in the height of the pea plants will be due to the environmental factor and not the genes. Risks Assessment: * Potting mixes contain microbes including bacteria/fungi * Inhalation of dust may irritate the nose/throat/lungs

LAB Report #3 Introduction: In this lab we have focus on Isolation of bacteria from environment. Microorganisms are found throughout the environment: in the air and water; on the surface of any object such as clothes‚ walls‚ furniture; in soil and dust; and on and in our own bodies (skin and mucous membranes). In order to demonstrate the ubiquity and diversity of microbes in the environment‚ samples from immediate areas of the environment and/or from your body will be obtained and cultured

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

"Nature and the Environment" "Ecology or the study of nature and the environment involves us in the conservation of the earth. We are at a point in the history of civilization where awareness of our fragile relationship to nature and the environment is high. We are losing 3‚000 acres of rain forest around the world and four species of plants and animals. More plants‚ insects‚ birds and animals became extinct in the 20th century than in any era since the Cretaceous catastrophe more than 65 million
