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. They bind to pathogens (infectious agents) and can signal the immune system to destroy these pathogens. Maintaining cell shape is a function of structural proteins (not antibodies). Regulating cell processes is often done by hormones or other regulatory molecules. Speeding up biochemical reactions is the role of enzymes. Sending electrical signals is related to neurons.

Answer:

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