100
Give an example of a virus.
Examples may vary:
The Flu
HIV
H1N1
Polio
100
How many cell(s) are bacteria made of?
One
100
What is the name for Archaea that live in extreme environments?
Extremophiles
100
What is Prokaryote Reproduction commonly called?
Binary Fission
100
What is this a picture of?
Virus
200
When a virus replicates extensively within its host, the host cell will eventually…
burst, releasing the viruses to infect new cells. This process typically results in the death of the host cell.
200
What is a thick-walled protective wall that helps bacteria resist harsh conditions?
Endospore
200
What are the Archaea called that live in highly salty environments?
Halophiles
200
What is the difference between where Archaea versus Bacteria are typically found?
Archaea live in extreme environments, while Bacteria live everywhere else.
200
Unlike living organisms, viruses cannot reproduce without this.
A host cell
300
What is the name of the protective protein coat of a virus?
Capsid
300
Give an example of helpful bacteria.
Answers may vary:
-Aid digestion (gut microbiome).
-Produce vitamins (Vitamin K in intestines).
-Decompose waste and recycle nutrients.
-Used in food production (yogurt, cheese)
300
Unlike bacteria, archaea lack this molecule in their cell walls.
Peptidoglycan
300
What is the name of the partition that forms during binary fission?
Septum
300
What are the three most common shapes in Bacteria and Archaea?
Spheres, Rods, and Spiral
400
What are the steps of the lytic cyle?
Step 1 - Virus Attaches to Cell
Step 2 - Virus Injects DNA/RNA Into Cell
Step 3 - Virus Hijacks Cell DNA, Turning it into a Virus Factory
Step 4 - New Viruses Break Out of Cell, Killing Host Cell
400
Unlike asexual reproduction, this process creates genetic diversity
Conjugation
400
What do you call Archaea that live in an environment that is extremely hot AND highly acidic.
thermoacidophiles
400
What virus is this?.jpg)
HIV
400
This type of RNA virus, like HIV, uses reverse transcriptase to integrate into the host's genome.
A retrovirus
500
what are the steps of the lysogenic cycle? How does this differ from the lytic cycle?
The lyosgenic cycle involves the same steps of the lytic cycle, however there is a period of dormancy between Step 2 and Step 3.
500
What is the difference between Gram-Positive and Gram Negative Bacteria?
Gram-Positive: Bacteria with a thick protein layer stain purple.
Gram-Negative: Bacteria with a thin protein layer stain pink.
500
The process where Archaea produce methane in oxygen-free environments, like in animal digestive systems.
Methanogenesis
500
Describe four differences between Prokaryotes and Eukaryotes.
Answers may vary:
-circular DNA with no membrane vs DNA made of up of chromosomes + bound by a nucleus
-Cell division by binary fission versus mitosis and meiosis
-asexual reproduction vs sexual reproduction
-unicellular vs multicellular
-no membrane-bound organelles vs membrane-bound organelles present
500
Viruses can make DNA from RNA using this enzyme.
Reverse Transcriptase
