The disease causing microbes are called pathogens.
it depends on whether the microbes are visuses causing colds etc. or whether they are benefictial to us.
Yes, viruses are considered microbes because they are microscopic organisms that are capable of causing infections in living organisms.
Majority of the microbes do not cause the disease. The disease causing microbes also, probably, keeps your species healthy and your immune system tuned.
when you get a disease you are said to be INFECTED by it .
A systemic disease effects more than one part of the body. A severe systemic disease is spread throughout the body and impacts the patient's life to a large degree, causing widespread pain and suffering.
Anaphylaxis
It aids in digestionIt protect us from some microbes that are pathogens. Some disease causing microbes are present in contaminated or food that are not properly treated. The acid pH of the stomach kills those microbes and protect us from disease.
Immune system to react and prepare the organism to fight future invasions by these microbes.
Its when Microbes(bacteria and fungi) grow on food causing it to decay and rot.They will multiply while on the food.
No, meat is parts of dead animal flesh. Microbes are living single celled organisms. What you may be thinking of is contamination with microbes. Yes, in that case raw meat is often (but not always) contaminated with microbes (often disease causing microbes that can make you very sick or even kill you). This is why meat should always be cooked before being served: to kill these microbes (even harmless ones).
No, not all microbes cause decay. While some microbes break down organic matter leading to decay, others play roles in fermentation, digestion, and other essential processes without causing decay. Microbes have diverse functions and can be beneficial in certain environments and applications.
