Material Appendix B – Identifying Bacteria Bacteria identification is accomplished in a number of ways. Two common tools microbiologists use to identify unknown bacteria include dichotomous key and biochemical tests. The dichotomous key is useful when a microbiologist only needs to know which group an unknown microbe belongs to on a general level. When a microbiologist needs to identify a specific bacterium‚ biochemical tests are used. PART ONE: GENERAL BACTERIA IDENTIFICATION Review the dichotomous

Doctors prescribed these medicines to cure many diseases. During World War II‚ it treated one of the biggest killers during wartime - infected wounds. It was the beginning of the antibiotic era.

This reaction behavior is very interesting to me because I would like to know how come humans get different reactions or feelings in certain situations. This topic leaves me with a few questions that I would like to figure out through research and study. First I would like to know what triggers human reactions to social encounters. Then I

The Growth of Bacteria Influenced by Different Antibiotics Introduction: Plants are made up of three basic kinds of tissue that help it carry out basic functions that are necessary to maintain life and proper photosynthesis. The first and outermost layer of tissue is called the dermal layer. This is the plant’s ‘skin’ and serves the plant mainly as a source of protection. Also present in the dermal layer of the leaves are stomata‚ which are tiny openings that allow carbon dioxide to enter

Earth. However‚ 65 million years ago‚ the most recent mass extinction seemed to have caused all of them to die-off. What caused the demise of the dinosaurs and 60% of life on Earth at the time? How did it affect life on Earth afterwards? Are all of the Dinosaurs dead? Will this happen to humans in the near future? The Cretaceous-Tertiary extinction event‚ or the K-T event‚ is the name given to the mass extinction of the dinosaurs and other species that took place about 65 million years ago

Effectiveness of Garlic in Fighting Bacteria Introduction This experiment determined whether garlic was effective in fighting bacteria. This project interested me because garlic is traditionally used in medicine and is known to combat bacteria. Hypothesis If bacteria is exposed to garlic‚ then the garlic will to abolish the Escherichia coli‚ because the Escherichia coli (E. coli) is usually a weak bacteria.

for sexual abuse or forced labor‚ the number of people becoming affected is increasing. Human trafficking has been an issue across the world for thousands of years. It first appeared in the 1400s when 20 million Africans were forcefully brought to Portugal to work as slaves and 20 percent died on the way due to terrible and unhealthy conditions when on the ships that transported them. Human trafficking affects people of all backgrounds‚ and for a variety of purposes relating to different genders and

on why bacterium evolves. Bacteria are single celled (eukaryotic) organisms. Bacteria is present in almost every environment‚ including the human body. They can absorb nutrients from various ways‚ some bacteria are photosynthetic meaning they absorb their nutrition from sunlight through a process known as photosynthesis‚ while other bacteria absorbs nutrients from the organism they live on or in. There is good bacteria and more dangerous “bad” bacteria. Bad bacteria can be dangerous to other species
