comes into contact with air where it is converted into sulfate (SO4). The sulfate is taken up by plants and microorganisms and is converted into organic forms; animals then consume these organic forms through foods they eat‚ thereby moving the sulfur through the food chain. As organisms die and decompose‚ some of the sulfur is again released as a sulfate and some enters the tissues of microorganisms. There are also a variety of natural sources that emit sulfur directly into the atmosphere‚ including volcanic

Causes and Spread of Infection Unit 22 ICO2 Q1 1.1 * Bacteria are unicellular‚ prolcaryotic microorganism found almost in all kinds of habits. Some bacteria are beneficial like those involved in nitrogen fixation and some pathogenic‚ which causes diseases. * Viruses are unicellular‚ tiny organisms which are mostly composed of DNA (Deoxyribonucleic Acid) and protein. Its body compromises of head and tail sections. Viruses attach themselves to other organisms and severe infectious diseases

With science there are many branches‚ one of these branches is Microbiology and within this specific branch theories have been created. It may not be obvious theories are ever evolving and go through changes and previous theories are falsified and new ones emerge. For instance‚ the theory of biogenesis was first introduced by a man named Rudolph Virchow‚ who eagerly challenged the current theory of spontaneous generation at the time. Spontaneous generation theory was the thought that some forms

s Disease can be divided in two main groups infections and non-infections. Infectious diseases are diseases that can be spread or transmitted from one organism to another. Non – infectious diseases cannot‚ be spread from one person to another. Infectious Diseases Infectious diseases are generally caused by microbes known as pathogens. Pathogens invade the host and can cause changes in the body that stop parts‚ or all‚ of the body working correctly. Pathogens contain antigens that are made of

from an animal to a person. The spread often happens via airborne viruses or bacteria‚ but also through blood or other bodily fluid. The terms infectious and contagious are also used to describe a communicable disease. A communicable disease chain is the chain of infection‚which includes: INFECTIOUS DISEASE:Any microorganism that can cause a disease such as a bacterium‚ virus‚ parasite‚ or fungus. RESERVOIR: The place where the microorganism resides‚ thrives‚ and reproduces‚ i.e.‚ food‚ water‚ toilet

Methods and Materials The design of this lab experiment is to isolate bacteria from any location or item without getting bacterial contamination from unwanted places. Microorganisms are found in dust particles suspended in the air or and on nasal secretions that are a result of sneezing (Department‚ 2009). Materials needed are: 100 ml of melted nutrient agar‚ five sterile petri plates‚ and sterile cotton swabs. The first
