Exam 1 Review Answers – Flashcards

• Study of Protosones
• Ex: Ameba

• Genetic Make Up
• How genes passed down

• Enviorment
• How they interact w/ enviorment and Microbes

• Microorganisms capable to adapt to enviorment
• Capable to make mutation in genes
• Result: become adapted ; now able to cause disease

• Bacteria
• Viruses
• Protozoa
• Helminths
• Algae

• Worms
• Cause ofinfection
• Positive Agent "X"

• First to observeliving Microbes
• Single lensmagnified up to 300x
• Names Animalcules (Microbes)
• Father of Bacteria

(P)Chromosomes in cekk, NO nucleus, lack organells

(E) Have organells ; Nucleus

(P) ; (E) are diff b/c they are ACELLULAR

w/nucleic acid protein

• Unicellular ;Multicellular
• Has nucleus
• Organells

• Techniques Experiment Biogenesis
• Showed Microbes caused fermenting and spoilage
• Developed Pasturization

• Disapproved spontanious generation and microorganisms
• Developed Rabies Vaccine
• Developed Germ Theory of Disease

Microbes that are newly discovered human pathogens

(HIV)

Mushrooms

;

• HEAT
• Theheight of temp kills Bacteria

• Requires the elimination of all life forms including spores & viruses
• HighTemp + High Pressure=Sterile

• Micrometers um
• Need Light Microscope
• Cant see with naked eye

Nanometers (nm)

Use Electron Microscope

Measured in milimeters (mm)

Can see w/naked eye

Change sequence of molecule

Take another microorganism & put a little of the DNA & then produce compunds of chemicals needed

• Bacteria
• Archaea
• Eukarya

• No Nucleus
• No Organells
• Unicellular
