Answer:
1. Adaptive radiation: A pattern of evolution in which slightly different species evolve from one common ancestor.
2. Coevolution: A pattern of evolution in which two species evolve in relation to each other.
3. Convergent evolution: A pattern of evolution in which similar characteristics evolve between two unrelated species.
4. Divergent evolution: A pattern of evolution in which very different species evolve from one common ancestor.
5. Gradualism: A theory of evolution that states that a species evolves by consistent, small, steps.
6. Punctuated equilibrium: A theory of evolution that states that a species evolves in spurts of rapid change and then no change.
You may be referring to the cytoplasm here. That is the "filling" within the cell. But if you are looking for specific transport of proteins, the ER folds proteins and then transport vesicles move them to the Golgi.
