Out of the three domains, Archaea, Bacteria and Eukarya, the vital differences may be identified in order to classify the cell. Eukaryotic cells possess membrane-bound organelles; on the other hand, the domains archaea and eukarya contain cells are prokaryotic, so they do not have membrane bound organelles. Moreover, they also possess ester linkages in their cell membranes, which allow them to survive more extreme environments (especially true for archaea). By studying the cell membrane of the cell, distinction can be made.

Which of these scientists is best known for his idea that characteristics an individual gains in its lifetime could be passed on
Anna [14]
This was Lamarck's idea. Here's an example: Suppose giraffes originally had short necks that they stretched to reach high-up leaves in the trees. This continuous stretching of the neck was passed onto offspring, who as a result had slightly longer necks. This continued for multiple generations until we get today's long-necked giraffe. Lamarck was on to something (that something being evolution by natural selection, which Darwin discovered), but his theory wasn't completely correct since organisms can only pass on genes (segments of DNA that code for a characteristic or function) to their offspring. Since "stretching" would not code into DNA, it wouldn't be passed onto offspring, proving Lamarck's theory incorrect.
