<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
Answer: 1. ribosome ( protein synthesis
2. Rough ER ( protein modification)
3. Transport vesicle ( protein transport between organelles)
4. Golgi apparatus ( protein modification & packaging for secretion)
5. Transport vesicle ( protein transport to plasma membrane )
6. Plasma membrane ( protein export from the cell)
Explanation:
Answer:
B. abiotic factors.
Explanation:
Abiotic factors describe soil and temperature in an ecosystem.
Plants are living organisms belonging to the kingdom Plantae. They include familiar organisms such as trees, herbs, bushes, grasses, vines, ferns, mosses, and green algae.
Answer:
The two populations might become separate species
Explanation:
Allopatric speciation is one of the mechanisms that can lead to the establishment of a new species of organisms as a result of geographical separation of different population of organisms of the same species.
<em>When organisms of the same species are geographically separated, this prevents gene flow between the two populations and each population develops various adaptive features in order to cope with their environments. Thus, each population might end up becoming a new species.</em>
