- ANSWER//bright field microscope
what are the different magnifications of a bright field microscope - ANSWER//4x
10x
40x
100x
what is the kind of microscope that you use when looking at a virus - ANSWER//electron
microscope
what are the different magnifications of the electron microscope - ANSWER//1 mil
2 mil
10 mil
How are microbes helpful - ANSWER//decompose organic waste
generate O2
produce chemical products such as ethanol and others
produce fermented foods ex: vinegar, cheese, and bread
,produce products used in manufacturing ex: cellulose and insulin
How many microbes are pathogenic out of all the microorganisms - ANSWER//70/10 mil
what knowledge do microbes give humans - ANSWER//prevent diseases
allow food storage and prevent food spoilages
stop transmission of diseases
Microbiology - ANSWER//the study of organisms too small to be seen with the naked eye
microbial ecology - ANSWER//the study of the relationship between microorganisms and their
environment
competitive exclusion - ANSWER//a way to kill the bad bacteria
- change in the pH
- secrete enzymes
- eat the food
bioremediation - ANSWER//using microbes to clean up pollutants
Bacillus thuringienisis - ANSWER//can kill insects but doesn't harm plants or animals
Order of the Scientific Method - ANSWER//observe
hypothesis
prediction
experiment
consistency
theory
law
, Mycology - ANSWER//study of fungi
bacteriology - ANSWER//study of bacteria
virology - ANSWER//study of viruses
algology - ANSWER//study of algae
protozoology - ANSWER//study of protozoa
Robert Hooke - ANSWER//• All living organisms are composed of little boxes or "cells"
• -came up with cell theory - that all microorganisms are made up of cells
-marked the beginning of the cell theory
Anton van Leeuwenhook - ANSWER//• 1st cells observed under the microscope
also made the original electron microscope : 10 mil X
Rebecca Lancefield - ANSWER//• came up with the system that help classifying different
microorganisms
• it was all based on different polysaccharides in the cell wall
also helped discover Streptococcus pyognes - which is basically strep and we know this
because pyognes is a pus forming microorganism
Joseph Lister - ANSWER//• discovered phenol: was used to stop surgical would infections
• usually in hospitals : Staphylococcus aures aka staph infection
at least 20% of population is a carrier for the staph infection and they carry it in their noses
Louis Pasteur - ANSWER//• father of microbiology and is the most important scientist in
microbiology
• showed that microbes are responsible for fermentation
