Question

which statements describe functions of antibodies? select two options.
they maintain the cells shape.
they regulate cell processes.
they protect the body from infectious agents.
they signal the immune system to destroy pathogens.
they speed up biochemical reactions.
they send electrical signals.

Explanation:

Antibodies are part of the immune system. Their main functions are to protect the body from infectious agents (by binding to pathogens) and to signal the immune system to destroy pathogens (by marking pathogens for destruction). Maintaining cell shape is a function of the cytoskeleton. Regulating cell processes can be done by hormones. Speeding up biochemical reactions is the role of enzymes. Sending electrical signals is a function of neurons.

Answer:

C. They protect the body from infectious agents.
D. They signal the immune system to destroy pathogens.
