found outside of the membrane

Your answer is "tiny structures in the cell that carry out the activities."

False. If members of a species become isolated, they will eventually evolve differently than the original population because the two groups are in different environments for which they may require different abilities. This type divergence (from separation) is called allopatric speciation.
