• temp
• moicture
• radiation
• chemicals

• food spoliage
• infections

• fermentation
• decomposition
• used to make/ produce chemicals (insulin)

• cocaus- round
• straphlococci- grape like clusters
• bacillus- rod shaped
• spirlla- spiral shaped

doors are airtight; chemical (decon)showers exist

all openings are taped; spacesuit is put on

sterilization with ultraviolet light; socks, glove

all clothers are removed and scrubs are put on

• 1. Helper T- identifies the incader and sends info to B cells
• 2. B cells- produce anitbodies specific to invader
• 3. Killer T cells- kills cells that invader has infected
• 4. Suppressor T cells- slow down and stop B/T cells when invader is contained
• 5. Memory cells- recongize antigen that has previously invaded the body which increases the immmune response time

gain energy by converting hydrogen gas into methan gas

salt loving

thrive in extremely hot and extremelt acidic conditions

vaccination is where the dead virus is injected to the body in order for the body to go through the process and be able to identify the virus the next time it enters the body

• 1. Attach- to the cell
• 2. Entry- DNA/RNA is injected into the cell
• 3. Repkication- the host cell if tricked into copying viral DNA/RNA
• 4. Assmbly- the host cell assembles new virus
• 5. Release- new viruses burst host cell and move on to infect other cells
