explained through science. I have always been fascinated to know how things work and why or how they happen. That is why microbiology is perfect for me. I like finding out how or why something can happen and I can do that if I go into the field of science. I have been looking into colleges and professions recently and I have become very interested in microbiology. Microbiology is the study of microorganisms. Microbiologists try to understand the organisms and how they interact with their

Microbiology is a field of science which typically is divided into several areas such as: bacteriology‚ virology‚ parasitology and immunology. The goal of microbiology is to increase the specific knowledge of a known microorganism and by extension counter the spread of harmful microorganisms and to learn practical applications of research results. A microbiologist studies the structure‚ metabolism‚ genetics and ecology of microorganisms such as bacteria‚ viruses‚ fungi or algae. A microbiologist

I. INTRODUCTION Independent Study Questions 1.) What is the fundamental difference between eukaryotic and prokaryotic cells? Procaryotic cells do not contain a membrane-bound nucleus or any membrane-bound organelles. Eurkaryotic cells contain both a membrane mound nucleus and membrane-bound organelles (making them far more complex). 2.) List and describe the two domains of prokaryotic organisms. a. Bacteria- Most are a specific shape (cylindrical‚ spiral‚ or spherical). Cell

H1N1: The Sneaky Killer I chose to write my topic paper on the H1N1 virus. This virus has interested me since its reemergence in 2009. Its ability to change and adapt each time it shows up again attracted my attention. I hope to inform people about the virus along with the symptoms and how to go about avoiding it if you can‚ or treating it if you have it. This pandemic is avoidable through a simple vaccine that can be taken as a shot or as a nasal spray. Overall I find the H1N1 virus to be interesting
