Which of the following is a form of cell communication that may be used during an immune response?

• A. Cells infected with a virus sending signals to prepare neighboring cells for viral infection.
• B. Electrical signals traveling between the cells of the heart to cause heart muscle contractions.
• C. Growth hormones signaling to the cells to increase tissue growth.
• D. Stress hormones triggering the 'fight or flight' response in the body.

Answer: (A)

Verified step by step guidance

1. Understand the context of cell communication in the immune response. This involves recognizing how cells interact to defend against pathogens.
2. Identify the role of signaling in immune responses. Cells often use signaling to alert neighboring cells of potential threats, such as viral infections.
3. Consider the specific scenario of a viral infection. Infected cells can release interferons, which are signaling proteins that help prepare nearby cells to resist viral replication.
4. Compare the options given in the problem. Focus on the option that involves cells sending signals to neighboring cells in the context of an immune response.
5. Recognize that the correct form of cell communication during an immune response is when cells infected with a virus send signals to prepare neighboring cells for viral infection.
