Answer 1

what would your best guess be?

Answer 2

I'd say the first one are Complete immunity, because passive and active are ways of acquiring the immunity. To the second question, i would say macrophage, because it is a type of white cell. Antigen is toxin or other foreign substance, antibodies are something IN the white cells and pathogens are harmfull.

Answer 3

Not 100% sure though.

Lifetime protection..... Has to be active immunity.

Answer 5

Antigen is an unwelcome guest

Answer 13

correct wrong and wrong.
Antigens are substances (usually proteins) that are on the cell,
Antibodies are proteins that bind to the antigens. This binding of an antibody to an antigen causes an immune response. Check the image.
