Unit 1 An overview of Microbiology 1. What prevented the science of microbiolgy from developing before the era of van Leeuwenhoek? 2. How did Pasteur's swan neck flask experiment show that the concept of spontaneous generation was invalid? 3. If the Chickungunya virus epidemic had first started in Jamaica, how would you identify the cause of the disease? 4. What is a pure culture? How is this important in microbiology? 5. How would you convince a friend that microorganisms are

Bacteria |I | |INTRODUCTION | Bacteria, one-celled organisms visible only through a microscope. Bacteria live all around us and within us. The air is filled with bacteria, and they have even entered outer space in spacecraft. Bacteria live in the deepest parts of the ocean and deep within Earth. They are in the soil, in our food, and on plants and animals. Even our bodies are home to many different kinds of bacteria. Our lives are closely intertwined with theirs, and the health

Position in Food chain. Another significant determinant of bioaccumulation if the position that an organism dwell in a food. Any variation of the food chain that improved the number of trophic levels was anticipated to increase bioaccumulation in top carnivores due to biomagnification happening at the respective step. Even though the position in the food chain is evidently significant to bioaccumulation, its effect is not continuously upfront for the reason that there is no continual rise in contaminant

First of all you need to know what exactly an oil spill is-it is when carelessness of the crew or equipment issues creates a problem that causes an oil tanker to leak out oil into the water. Oil spills can have other motives behind them as well such

A New Approach to an Enduring Problem Today, a growing world population and the rise of “developing” nations are creating a strain on world resources never before witnessed. Faced with this trend, businesses can no longer afford to continue along the path of “being less bad” through traditional green practices. Cradle to Cradle offers a transformational new approach to solving this problem, one that embraces the power of human innovation rather than attempting to limit it. An analysis of the

INTRODUCTION Soil is the thin layer of organic and inorganic materials that covers the Earth's rocky surface. The organic portion, which is derived from the decayed remains of plants and animals, is concentrated in the dark uppermost topsoil. The inorganic portion made up of rock fragments, was formed over thousands of years by physical and chemical weathering of bedrock. Productive soils are necessary for agriculture to supply the world with sufficient food.

[pic] WHAT IS GREEN TECHNOLOGY? The term "technology" refers to the application of knowledge for practical purposes. The field of "green technology" encompasses a continuously evolving group of methods and materials, from techniques for generating energy to non-toxic cleaning products. As the name implies green technology is one that has a "green" purpose. By green we do not mean the color, however, nature is quite green, and the long and short term impact an invention has on the environment
