1.Microbes decompose dead organisms, aid the digestive processes of gazing animals, and capture energy from the Sun. 2.Viruses were initially identified as small infectious agents that could pass through filters. They borrowed the use of existing metabolic and replicative mechanisms of the host cells they infected to survive. 3.A microorganism that causes disease is pathogenic 4.Microscopes which allowed for the direct observation of microbes were a crucial discovery in the microbiology field. 5.Algae never cause disease in humans. 6.A substance derived from one microorganism that kills or restricts the growth of other microorganisms is best described as antibiotic. 7.Microbiologists investigate problems by designing and carrying out experiments. .A good hypothesis is one that offers the simplest most reasonable explanation and can be tested. 8.Vaccines are: preparations that establish immunity to a disease 9.Bioterrorism: uses microbes, such as anthrax, as part of terrorist attacks 10. Bacteriophages are: viruses that attack and kill specific kinds of bacteria including antibiotic resistant bacteria 11. Before Ehrlich began a systematic search for a chemical to kill specific bacteria, the only chemotherapies available were substances derived from medicinal plants. Ehrlich systematically tested hundreds of compounds for their ability to destroy specific bacteria without damaging surrounding tissue. 12. Edward Jenner is best known for Developing some of the earliest vaccines 13. Viruses, protozoa, and bacteria are all considered microbes. 14. Microbes have played important roles in genetics and in the discovery of DNA as the genetic material. The ability of a previously harmless bacterium to change into a disease-causing bacterium was due to DNA acquisition. 15. The period from 1874 to 1917 is generally referred to as the golden age of microbiology; microbiology was at the forefront of biomedical research in medicine and biology 16. Microbiology continues to be an important research field for all of the following reasons: new and emerging diseases like AIDS need to be studied microorganisms can be used as factories to cheaply produce drugs, hormones and vaccines many forms of genetic engineering depend on microorganisms. 17. Because viruses could not be visualized using conventional microscopes further progress required the development of techniques for isolating, propagating and analyzing viruses. 18. The English scientist Robert Hooke coined the term cell because the small boxes he saw in the microscope reminded him of a monk's room. What is the cell theory that was later proposed? Cells are fundamental units of life 19. The curve in Pasteur's swan neck flasks was important It trapped microbes that otherwise would have entered the 20To design a good experiment, an investigator must consider all variables that might affect the outcome. What is a variable? anything that can change for the purpose of the experiment 21The field of immunology involves studying how a person defends him/ herself against microbial infection.
