Question

question 9 of 10
how have chemists helped fight leukemia?
a. chemists have developed a vaccine to prevent leukemia.
b. chemists have developed medicines to fight leukemia.
c. chemists study body parts that are affected by leukemia.
d. chemists take care of patients in the hospital with leukemia.

Explanation:

Chemists are involved in the development of chemical - based substances. Vaccines are typically developed by immunologists (though chemists may have some role in adjuvant development, but not the main vaccine for leukemia). Studying body parts affected by leukemia is more of a biology/anatomy or pathology task. Taking care of patients is a nursing or medical practice role. Developing medicines (which are chemical compounds in most cases) to fight leukemia is a key role of chemists as they work on synthesizing, analyzing, and formulating drug molecules.

Answer:

B. Chemists have developed medicines to fight leukemia.
