ONE
What do people do to kill bacteria off their food?
Cook it, keep it refrigerated, wash it, or salt it
What type of medicine is used to kill bacteria?
Antibiotics
How do viruses reproduce?
Viruses attach themselves to a host cell, inject their genetic material, and then hijack the host cell to reproduce for the virus
What is the main human defense against viruses?
Immune System
How do Bacteria reproduce?
Binary Fission
When a virus gets replicated so much inside its host, eventually the host cell will . . .
explode and let out all the viruses to attach new cells. The host cell dies.
What type of organism can be found in extreme environments such as hot springs?
Archaea
What is the protective coating of Protein around a virus called?
Capsid
What is the difference between a Eukaryote and a Prokaryote?
A Eukaryote has a nucleus, while a Prokaryote does not. (And other stuff)
Viruses are not living things because...
They do not perform life functions like living things do. They do not grow, can't reproduce on their own, do not use nutrients for energy, or maintain homeostasis.
What are the three types of Archaea?
Heat lovers, salt lovers, and cold lovers (methane producers)
What are viruses that contain RNA instead of DNA called?
Retrovirus
What do bacteria use to move around?
Flagella
Explain the steps of Binary Fission.
Step 1 - Cell Grows
Step 2 - DNA Copies
Step 3 - DNA Separates
Step 4 - Cell Splits
What are the steps of the lytic cycle?
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
What is the name of the process where a virus infects a cell and reproduces using the host cell?
Lytic Cycle
Bacteria are found in which three shapes?
rods, spirals, spheres
