I NEED THIS ASAP 20 POINTS, 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.

1) Viruses
Harmful: Marburg virus
Harmless: Bacteriophages

Bacteria
Harmful: E. Coli
Harmless: Lactobacillus

Fungi
Harmful: fungal eye infections
Harmless: Agaricus Bisporus

Protozoa
Harmful: Giardia
Harmless: Nonpathogenic intestinal Protozoa

Worms
Harmful: heart worms
Harmless: pinworms

2) Nonspecific immunity protect the body from bacteria, viruses, and pathogens while specific immunity only protect the body from specific pathogens.

Nonspecific immunity examples: Fever, proteins, cellular defenses

Specific immunity: active immunity, passive immunity, natural immunity, and artificial immunity.

3) 5* examples of white blood cells:
Monocytes
Lymphocytes
Neutrophils
Basophils
Eosinophils
*(There are only 5 different kinds of white blood cells, maybe your teacher made a mistake with putting 6)*

The red cells are at the bottom and the white cells are on top of the red cells

I don’t know number 4 I’m sorry

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
