Because there are so many different sorts of pathogens
There are so many different types because they are all used for different purposes in different situations.
Definitely. The only reason you don't get a sickness twice is because your body has produced antibodies to attack the viruses before they spread. Food poisoning can come from anything that has happened to the food, so there are many different types of food poisoning. There are also many different types of food that you can get food poisoning from.
Antibodies are the garbage trucks of organic systems. If they did not remove the SPECIFIC molecules from each system, there would be so many space occupying lesions that the system would be burdened similiar to a vine choking off a tree with overgrowth. It is that simple, physical, not process integrated. Joseph F. Nowoslawski
The petroleum industry consists of so many different types of processes because so many different things can be made from petroleum.
Do you mean, why are there many different types of poems?
There are many different types of scientists because one person could not handle all the information of geology, astrology, and other types of science. Since there are numerous types of sciences, there has to be many different types of scientists, so there are many different scientists because there are many different sciences.
different enviroments lead to different types of them and also due to their diet
Antibodies stick to any viruses or infections. They don't attack, but they are like homing devices. They track the diseases so white blood cells (the attackers) know where the diseases are.
Many different moment throughout history created different forms
By definition, antibodies act against particles, proteins, microbes, and viruses. Each antibody has to be a "match" or a "fit" to work against what it is working on. So if you have had chicken pox, you made antibodies to act against it and inactivate it. If you are exposed again, you will not get it. If you get a blood transfusion it must match or your antibodies will inactive it and will cause a reaction that will hurt you. Think of all the things you have come across: different pollen from different plants, different colds, different flu (you have to get a new shot every year as it is different), different vaccines. It just goes on and on.
