Question

how does the use of cell technology benefit public health?
○ it makes it possible to discover new anticancer drugs.
○ it makes it possible to culture fewer types of cells.
○ it makes it possible to regulate medical research.
○ it makes it possible to avoid testing drugs in humans.

Explanation:

Cell technology (like cell cultures, stem cell tech) is used in medical research to test drugs/therapies without human trials first (e.g., using cell models to assess safety/efficacy). Option 4 (It makes it possible to avoid testing drugs in humans) aligns with this—cell tech allows pre - clinical testing on cells instead of humans initially. Other options: Discovering new anticancer drugs is a result but not the core benefit of “public health” - focused cell tech use here; regulating research is not a direct benefit of cell tech use; culturing fewer cell types is incorrect (tech often allows more or specific cultures).

Answer:

It makes it possible to avoid testing drugs in humans.
