the diversity of antigen receptors in both B cells and T cells is a result of shuffling and rearranging a few hundred versions of several smaller gene segments. This process is called genetic recombination.
There are many defense mechanisms the human body has to prevent illness/infection. Your skin is unable to be penetrated by bacteria and viruses, which is why you need to wash any cut of scape or wound to prevent infection. You have hairs in your nose to help keep out foreign particles that would let germs in. When you inhale a foreign object your body senses it and trys to cough it out. There are cilia in your lungs that push foreign particle out. Your body also has an intricate defense system to kill any foreign bacteria or virus that doesn't belong using leukocytes etc. to kill them.
an army of small people have created a fort (your skin) and they have people posted every day ready to fight off any bad organisms (illness).
By sick - if you talking about getting the fever then your body tries to maintain the normal body temperature which is 37 degree Celsius by increasing the metabolic rate.
Virus
Generally a person is sick well before symptoms show, so it is not as fast as you would think. Symptoms will show more rapidly b/c your body is trying to defend itself against an invader. It only seems very fast because it is a bigger change than what we are used too.
It is a toxin released from the frog onto his skin to protect itself. I learned about this while in the U.S. Territory of GUAM. I know the frog comes from Australia and can grow to get pretty big. If they release the toxin and your dog licks or picks the frog up with its mouth it will get them sick and can be fatal for puppies still developing immune systems.
Not one certain organelle controls homestasis . homeostasis is when your body is normal or in balance . so if your sick then your body will reguratate also know as throwing up . your body does this to get the bad toxins out so your body can not be sick so in other words its maintaining homeostasis.
To protect the body against foreign particals, or just protecting your body from getting sick, or helping it get better when it is sick, think of it as police
to prevent harmful things from getting into the body such as viruses and bacteria. it also fights off disease abd whatnot.
Not by itself. But being cold will will put a strain on your body, leaving less energy for the immune system to protect you from diseases.
Your body has the ability to tackle most diseases. If you are given a small amount of a germ, your body can fight it and will teach itself how to protect itself if you are hit a by a full-blown attack. When you get a vaccination they put in a dead or weakened pathogen (a bad germ that makes you sick) in your blood stream. This vaccination tricks your immune system (the system that fights off germs) into thinking that you are sick. So it sends out antibodies (the things that fight off germs), and once they're made they stay in there forever therefore keeping you from getting sick.
They fight of bacteria and infections that are plaguing your body. Simply put, they keep you from getting sick and help you get better if you do get sick. And also are part of ur natural defense system
Yes to protect them from getting sick!
Advantages of antibodies are that they help the body resist getting sick. Disadvantages include the antibodies causing the immune system to attack itself. This issue is categorized as an autoimmune disorder.

If you are sick chances are that you are dehydrated, it takes a lot for the body to heal itself, using water and energy. Hope this helped ^^
By getting so sick that your body raises its temperature to kill the sickness.
