Question

Which issue is a negative effect of cell technology on society?
A. Immortal animal cell lines can be used to model human cells.
B.The use of human cells in research can lead to ethical problems.
C.Organ culture increases the time between donation and transplant.
D. People are more aware of the results of cell technology research.

Answer 1

thoughts? these are all effects of cell technology but only *one* is negative

if you're still stuck, try eliminating *positive* effects, like A (helping us model human cells is a good thing because it helps with research) and C (decreasing time between donations + transplants helps people who need transplants)

between B+D which one is more negative?
