It may become endangered </h2>
Explanation: <u><em>If organisms cannot adapt to the changes in their ecosystem, they may move to another location. If they will not move, the species may become threatened, endangered, or extinct. Under an evolutionary phenomenon called relaxed selection, traits that were advantageous in one time and place become obsolete in another. Traits that aren't actively maintained by natural selection tend to become smaller or less functional over time, studies suggest.</em></u>
<span>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) </span><span>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 </span><span>an alternative for organs from donors, and will not increase the time btween donation and transplant</span><span>
3) People are more aware of the results of cell technology research.
</span>-----> Awareness of research lead to greater understanding and unity
All plant cells because all plants and or trees use photosynthesis for the same thing.
The answer is D
Explanation:
I apologise for the late answer, but D would be the best one, as it does not discuss morality or anything differing from person to person. The effect it has on birds however, can be readily studied using the scientific method.
The answer is incomplete dominance! :)
