After an initial infection, B-cells recognize the measles virus. How is this helpful in human immune response?

A The B-cells use this recognition to defend the body against other pathogens, such as bacteria.

B The B-cells more quickly recognize and respond to any other virus that invades the body.

C The B-cells produce antibodies more quickly if the measles virus is encountered again.

D The B-cells transfer this recognition to T-cells, which will then devour the viruses.

What is the main function of leaves?

A Leaves provide support for growth and a place to store food.

B Leaves provide a place for photosynthesis to occur.

C Leaves absorb water and minerals and transports nutrients to the stem
