PLEASE SOMEONE DO THIS, The questions are:
1) Mention 5 different types of pathogens and mention within each type one harmful and one harmless example.
2) What is the main difference between nonspecific and specific immune responses? Mention 3 examples for each of them.
3) Mention 6 examples of white blood cells. When blood is centrifuged, where do white blood cells are found?
4) Be able to mention all of the steps involved in humoral and cell mediated immunity. After mentioning the 4 steps, explain what is the reason every step is happening. Have in mind that you need to explain 8 steps, since there are 4 per mechanism.
