Question 1 of 15

1

Select one of the following:

True
False

Explanation

Question 2 of 15

2

Select the correct definitions of a Primary Immune Response.

Select one or more of the following:

Slower, Smaller, Shorter
No symptoms felt by the infected person
Memory Cells produced
Occurs during the second exposure to the antigen

Explanation

Question 3 of 15

1

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

Select one of the following:

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

( Natural Passive Immunity, Natural Active Immunity, Artificial Passive Immunity, Artificial Active Immunity ) is when antibodies are passed from the mother to the baby through the placenta and/or breast milk.
( Natural Active Immunity, Natural Passive Immunity, Artificial Passive Immunity, Artificial Active Immunity ) is when antibodies are produced when you have caught the disease.
( Artificial Passive Immunity, Natural Passive Immunity, Natural Active Immunity, Artificial Active Immunity ) is when antibodies are injected into you from another organism.
( Artificial Active Immunity, Natural Passive Immunity, Natural Active Immunity, Artificial Passive Immunity ) is when antibodies are produced after exposure to the antigen through a vaccine.

Question 13 of 15

8

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.

Question 15 of 15

13

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.
