An immune response that occurs in the human body is shown above. This activity helps to do which of the following?
Produce antibiotics to control disease
Provide protection against a specific pathogen

After an initial infection, B-cells recognize the measles virus. How is this helpful in human immune response?
The B-cells use this recognition to defend the body against other pathogens, such as bacteria.
The B-cells more quickly recognize and respond to any other virus that invades the body.
The B-cells produce antibodies more quickly if the measles virus is encountered again.
The B-cells transfer this recognition to T-cells, which will then devour the viruses.
