Which issue is a negative effect of cell technology on society? immortal animal cell lines can be used to model human cells. the use of human cells in research can lead to ethical problems. organ culture increases the time between donation and transplant. people are more aware of the results of cell technology research.

The use of human cells in research can lead to ethical problems

Because the new use of cells most often lead to this "grey area" in ethics as it is a new area of science and our society is not yet conditioned to this scientific breakthough. As there is no "moral code" on human cell use, ethical objections can arise and led to conflicts.

When looking at the other options they do not cause negative effects on society

1) Immortal animal cell lines can be used to model human cells.
 > This technology is not yet developed so it cannot be negative (yet)
2) Organ culture increases the time between donation and transplant.
> Organ culture are actualy an alternative for organs from donors, and will not increase the time btween donation and transplant
3) People are more aware of the results of cell technology research.
> Awareness of research lead to greater understanding and unity

Bohr models are used to predict reactivity in elements. Reactivity refers to how likely an element is to form a compound with another element. When looking at Bohr models, we look at its valence electrons (the electrons on the last energy level) to determine reactivity.
