Answer 1

The main reason for this is to avoid... what?

• Joanna is culturing bacteria for her class's investigation.
• She makes sure to incubate the cultures at no higher than 25°C.  
• Growing pathogens that are harmful to humans
• Understand why, in suitable conditions such as those inside a human body, microorganisms (e.g. bacteria and viruses) can reproduce rapidly to produce very large numbers.
• Population growth of microorganisms given appropriate data.
• Understand that white blood cells are part of the body’s immune system and can destroy microorganisms by engulfing and digesting.
• Harmful Microorganisms :  Except for genetic and congenital factors, most of the diseases are caused by certain microorganisms.
• These microbes are called pathogens.
• They are specially adapted to infect and multiply within a host. Some diseases caused by pathogens are polio, cholera, mumps, rabies, malaria etc.
• Some microorganisms are not harmful, in fact, some are quite helpful (like the bacteria that is found in your gut).
• But a majority of them cause a lot of diseases in man and other organisms.

• Microorganisms include bacteria, algae, fungi, archaea, and protozoa.
• Most of the microorganisms that we know are free-living, while other are parasites.
