macrophages

Answer 1

Answere : I think the correct answere for option 1 is : antibodies because when antigen (alien) is already present in human body (space station) the white blood cells send antibodies to neutralize the antigen as many as possible till the white blood cell or lymphocytes multiplies or duplicate.

The correct answere for option 2 is : autoimmunity because some antibodies may develope response against own antigen or cells. This cauaes a fatal effect on human body.
