Question 2: Lister
Answer:
(antiseptic technique) proposed that during surgery we should blow chemicals over the tools being used in surgery to make them cleaner
Question 3: Fungi
Answer:
eukaryotic
Question 4: basic research
Answer:
simply trying to understand how these creatures functions so we can stop them from functioning or use them
Question 5: Pasteur
Answer:
put the end to spontaneous generation. He discovered that life can only come from living things.Created experiment to test whether sterile nutrients broth could spontaneously generate microbial life.
Question 6: medical micro
Answer:
epidemiology, how we can use our knowledge to fight diseases
Question 7: Redi
Answer:
created spontaneous generation- a belief that living things could arise from nonliving matter. He was able to disprove the theory that maggots could spontaneously generate from meat.
Question 8: scientific process
Answer:
is all observation based
- formulate a hypothesis
-experiment -see if the outcome is supported or not supported by the hypothesis
Question 9: theory
Answer:
is an explanation of a set of related observations or events based upon hypotheses verified multiple times by groups of researchers.
Question 10: Differential interference contrast
Answer:
description of image: image appears three-dimensional
uses: to observe internal structure of living microbes
Question 11: Snow
Answer:
(epidemiology) came up with idea of pinpointing on a map where diseases are happening. Realized that water was causing a disease, because on the map there was a cluster of sick people in one area
Question 12: magnification
Answer:
making stuff bigger
Question 13: industrial micro
Answer:
use micro to create different things. EX: brewing beer
Question 14: Protozoa
Answer:

Answer:
cells without a nucleus. They are found in single-celled organisms, such as bacteria.
Question 21: what is the lifestyle of microbes?
Answer:
-free-living, live in water, dirt, or a leaf, etc.-requires a host
Question 22: applied environment
Answer:
use our knowledge for advantages. EX: oil spills
Question 23: Transmission
Answer:
description of image: monotone, two-dimensional highly magnified images; my be color enhanced uses: to observe internal ultrastructural detail of cells and observation of viruses and small bacteria
Question 24: wavelength
Answer:
what kind of energy you are using for visualization, visible light as an energy source.
