What is the word equation for aerobic respiration
Glucose +oxygen = carbon dioxide + water
What is the optimum tempature for bacteria to grow
37 degrees
What is an epidemic
A disease that effects a large number of people within a community, population or reigon
What is a pandemic
An epidemic that spreads over multiple countries or continents
What is a pathogen
A microorganism that causes disease
What are ways our body protects ourselves from microbes
Skin
Nose hurt
Nose and windpipe mucus
Eyes make tears
What does an eating microbe do
White blood cells move to your cut and eat the microbes in your blood, they can even squeeze out of the blood vessels to hunt for microbes that haven’t reached the blood
How many ways does a making antibodies have to destroy microbes
3, (missiles, puncturing holes in the microbes) (glue sticking together big groups of microbes for the eating microbes) (policemen surrounding and stick to the microbes making them harmless)
What is a vaccine
A dead or weakened pathogen which is inserted into you so that you get immunity due to the fact your body knows how to handle it
