Are viruses and bacteria living or nonliving, why or why not?
Virus- nonliving, viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy; they don't have all of the characteristics of a living organism.
Bacteria- living

What is the difference between a Eukaryotic and Prokaryotic cell?
A prokaryotic cell does not have a membrane bound nucleus while a eukaryotic cell does. Prokaryotes are unicellular while eukaryotes are often found multicellular. Prokaryotic cells are way smaller than eukaryotic cells.

What are bacteria?
Bacteria are microscopic prokaryotes.
100
What is a virus?
A virus is a strand of DNA or RNA surrounded by a layer of protein.
100
What allows the ability for bacteria to move?
flagellum
200
Are bacteria and viruses unicellular or multicellular?
Virus- 0 cells(nonliving)
Bacteria- unicellular

What is the difference between binary fission and conjugation?
Binary fission is one bacterium splits into two identical cells, this can happen in as little as 20 minutes. While conjugation is two bacteria of the same species attaching to each other and combining their DNA.
200
What does a bacterial cell lack?
No nucleus or membrane bound organelles such as mitochondria.
200
What does a virus lack?
No cell wall, no nucleus, or any organelles such as the mitochondria

What is the difference between anaerobic and aerobic?
Anaerobic describes bacteria that do not need oxygen to live.
Aerobic describes bacteria that need oxygen to live.

How do we treat viruses?
Virus- Viruses can't be treated with antibiotics because they don't affect/work on viruses and in some cases they can make them stronger. But once your body is affected with a virus your body builds immunity the virus, and those immunities are called antibodies. Another way to treat viruses by getting a vaccine. A vaccine can weaken a virus which symptoms less severe. Antiviral drugs can also make the symptoms less severe.

How can bacteria be helpful?
Helpful- Bacteria can make foods such as yogurt and cheese. They can also be decomposers and break down waste, they can clean up environmental pollution(bioremediation), provide nitrogen to plants(nitrogen fixation)
300
What three shapes do bacteria usually come in?
Cone, sphere, or a rod
300
What happens when a virus enters a host cell?
It inserts its DNA, so when the cell divides, the viral DNA copies over and over, destroying the host cell and infecting other cells.
300
What are the two kingdoms of bacteria?
Kingdom Archaebacteria
Kingdom Eubacteria
400
Are ebola, the mumps, HIV, the flu, and chicken pox viruses or bacterial diseases?
Viruses
400
How can bacteria be harmful?
Some bacteria are pathogens, which are organisms that cause disease. And some bacteria can cause food poisoning.
400
Which of the following is not a bacterial shape?
B
400
Which of the following term is defined as protective protein coat that surrounds genetic material (DNA or RNA) of a virus?
a) Endospore
b) Bacteriophage
c) Capsid/Capsule
d) Prophage
C
400
What is an endospore and why might bacteria needs to form one?
Endospores are sturdy structures formed by some bacteria to survive in unfavorable conditions like high heat or freezing temperatures.
500
Are tuberculosis, cholera, and ringworm viruses or bacterial diseases?
Bacterial Diseases
500
How can we treat bacteria?
Bacteria can be treated with vaccinations and antibiotics, and you could use pasteurization which is the process of heating food to a temperature that kills most harmful bacteria.

What are vaccines and why might you need one?
A vaccine is a mixture containing material from one or more deactivated pathogens, such as a virus.
