Why is it beneficial to our immune system that many pathogens have several different antigens?

Selecciona una de las siguientes respuestas posibles:

More antigens mean its a bigger pathogen so it'll be noticed more easily
More antigens mean that more B-Cells and T-Cells can be activated
It's not beneficial - it's too confusing for the B-Cells and T-Cells
Antigens stop the toxins being released

A phagocyte follows the trail of ❌ left by the pathogen up the concentration gradient.
When it gets near the pathogen, the phagocyte starts stretching out its cell membrane around the pathogen. These 'arms' are known as ❌ and allow the phagocyte to ❌ the pathogen and form a ❌ or phagocytotic vacuole.
❌ in the phagocyte travel to this vesicle, fuse with it (a ❌) and release their ❌ enzymes into it, breaking down and destroying the pathogen.
The waste is released in ❌ and often the antigen(s) of the pathogen are displayed on the cell surface of the phagocyte.

Put these stages of an Immune Response in order of when they occur and match the correct definition to them:
❌ - Phagocyte ingests pathogen and displays its antigens on its cell surface membrane.
❌ - A ❌ with a ❌ to the antigen comes into contact with the phagocyte.
❌ - The T-Cell begins ❌, producing ❌ with the complementary receptors.
❌ - ❌ are released by the T-Cells, stimulating ❌ to divide to form ❌ and phagocytes to perform ❌. ❌ are also created.
