Question

what would cause antibodies to attack the cells of the body?
the cells support bacterial growth.
the cells are worn out and need to be replaced.
the antibodies mistakenly identify the cells as foreign material.
the red blood cells are malfunctioning.

Explanation:

To determine the cause of antibodies attacking the body's cells, we analyze each option:

• "The cells support bacterial growth": Antibodies target foreign invaders, not cells supporting bacteria (this is not a typical trigger for auto - attack).
• "The cells are worn out and need to be replaced": Worn - out cells are usually removed by other cellular processes, not antibody attack.
• "The antibodies mistakenly identify the cells as foreign material": In autoimmune disorders, antibodies (part of the immune system) can have a misrecognition, treating the body's own cells as non - self (foreign), leading to an attack.
• "The red blood cells are malfunctioning": Malfunctioning red blood cells are not typically attacked by antibodies as a primary cause of auto - attack (unlike in cases of misidentification as foreign).

Answer:

The antibodies mistakenly identify the cells as foreign material.
