Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

____ combine chemically with substances that the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood. A blood protein produced in response to and counteracting a specific antigen

A	Antibodies
B	Antigens
C	Pathogens
D	Posibodies

Explanation:

Detailed explanation-1: -Antibodies help the body to fight microbes or the toxins (poisons) they produce. They do this by recognising substances called antigens on the surface of the microbe, or in the chemicals they produce, which mark the microbe or toxin as being foreign. The antibodies then mark these antigens for destruction.

Detailed explanation-2: -Antigens are substances (usually proteins) on the surface of cells, viruses, fungi, or bacteria. Nonliving substances such as toxins, chemicals, drugs, and foreign particles (such as a splinter) can also be antigens. The immune system recognizes and destroys, or tries to destroy, substances that contain antigens.
