Water Analysis Lab Report
What was the MPN for your water sample?
MPN was 29 because in the 0.1 mL tubes only one contained gas, in the 1.0 mL tubes all
three contained gas, and in the 10 mL tubes all three contained gas.

In this analysis of Peter Earleys Crazy, the main issue that the author brings up
will be discussed, as well as his central claim. I will also look at some of the assumptions
that Earley makes, along with some evidence he provides, the strength

Basic unit of chemistry.
2. What is a molecule?
A group of atoms together. The smallest unit that can take part in a chemical
3. What is the major difference between covalent and non-covalent bond
1. Introduction to Microbes
1. What is a key feature that distinguishes viruses from bacteria from cellular forms
Viruses are not cells.
2. Are some bacteria capable of photosynthesis? If so, give an example of a group
of photosynthetic bacteria.
1. How is a simple microscope different than a compound microscope?
Single lens, multiple lens
2. What is the magnifying power of a microscope?
The ability to magnify objects, related to the focal length of a lens.
3. How is a microscope dif
4. Prokaryotic Cell Structure
1. Make a list of the three domains of life
Bacteria, archaebacteria, eukarya.
2. Name the main features that distinguishes a prokaryote from a eukaryote
Prokaryote lack nuclear membrane and many organelles.
3. What are the A
immunity ability to _; 2 basic variations
innate immunity is the bodys general ability to deal with:
mostly involves _cells that recognize general attributes of pathogens and
destroy them; many times sufficient to deal with invaders
Microbial Growth & Control
What is growth? for microbe, increase in: number of cells
usually binary fission 
generation time (g) from one division to: next division
minimum genetically determined for species
also varies with environment and nutritiona
Genetics of Prokaryotes
to do genetics need to: make mutants and move them
plan: what are mutations; then gene transfer in bacteria
a bit about recombination of new DNA in recipient cell
what is a mutation? any change in: DNA nucleotide sequence
some respiratory disease pathogens can be spread by direct contact; as well as aerosols; that
brings us to Staphylococcus
can be spread by respiratory aerosols and food, but also often by direct contact
Drugs and Epidemiology
Antimicrobial Agents Used In Vivo (internally)
Synthetic Antimicrobial Drugs and Antibiotics (naturally occurring antimicrobial agents)
common parameters and concerns involved, primarily _
ability of compound to _ or _ some group of
Metabolic Diversity of Microbes
Photosynthesis - conversion of light energy to chemical energy (i.e. ATP)
Phototrophs carry out photosynthesis
many phototrophs are also autotrophs
photoautotrophs produce ATP and fix CO2 C6H12O6 (sugar)
CO2 fixation requir
Microbial Ecology and Ecosystems

Microbial Metabolism Overview
Macronutrients: C, N, P, S, K, Mg, Ca, and Na
~50% dry weight of cell is carbon; 2 possibilities
heterotrophs require reduced C compounds
autotrophs can fix CO2 (CH2O)n

Why do cells regulate biosynthetic processes?
conserves energy and resources important in competition
two major levels of regulation in the cell:
1. one controls the activity of: pre-existing enzymes
