100
2 main parts of every virus
Genetic material (nucleic acid) and capsid (protein capsule)
100
What do antibiotics do?
Kill harmful bacteria
100
1? 7? 8? 9?
1 - pili
7 - capsule
8- genetic material
9- flagellum
100
How do bacteria contribute to the food chain?
Provide food for consumers, produce oxygen, break down dead organic matter, and create nitrogen compounds
100
What is an extremophile
Thrives in extreme environments
200
What is a bacteriophage
Virus that attacks bacteria
200
the process of heating liquids to kill harmful bacteria
Pasteurization
200
What are endospores?
Protective structure around DNA to keep it safe in harsh environmental conditions
200
thin, whip-like structure that helps an organism move through liquids
Flagellum
200
What is one example of where an extremophile may live?
volcano, deep ocean vent, hot springs, acidic environment, or places with high salt content
300
What you need to see a virus.
What is an electron microscope?
300
What is the difference between a vaccine and an antibiotic?
A vaccine is a weakened or inactive pathogen given to allow your body to form antibodies for a particular virus. Antibiotics are medicine that kill harmful bacteria.
300
Difference between flagellum and pili
Flagellum - long, for movement. Pili - many short.= for anchoring and attachment.
300
Cell division in which one cell splits into two identical daughter cells
Binary Fission
300
What is binary fission?
Asexual reproduction of bacteria
400
Two ways a virus is classified
Shape and the type of organism it infects
400
Difference between antigen and antibody
Antigen is the protein on the surface of a pathogen that your body uses to ID it, antibody is what your body makes in response so that it can remember pathogen for future
400
What is a capsule?
Slimy outer coat that helps bacteria stick to stuff and protects it
400
Relationship in which one organism lives on or near another organism and at least one of the organisms benefits.
Symbiotic
400
Differences between archaea and bacteria
Different cell wall composition, genetic information, and chemical structure
500
Why are viruses not considered living organisms?
Can not reproduce on their own - they require a host, not made of cells
500
How are vaccines made?
A vaccine is weakened or inactive virus that is injected to allow your body to form antibodies and memory cells, teaching it to fight off real pathogen.
500
3 shapes of bacteria
coccus - round
spirillum -spiral
bacillus - rod-like
500
Some archaea and bacteria are autotrophs. How do they make their food?
Photosynthesis

Similarities between archaea and bacteria
1. prokaryotes
2. unicellular
3. autotrophs and heterotrophs.
4. reproduce by binary fission or budding.
