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 (e.g., phagocytes) to destroy these pathogens.

• Maintaining cell shape is a function of structural proteins like cytoskeletal proteins, not antibodies.
• Regulating cell processes is more related to hormones or some regulatory proteins, not antibodies.
• Speeding up biochemical reactions is the role of enzymes.
• Sending electrical signals is a function of neurons (nerve cells) and related ion - channel proteins, not antibodies.

Answer:

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