Help me answer these questions

1. What is rebase used for in the centralized workflow?

2. In the feature branch workflow, are feature branches checked in to GitHub (you can read any reference to BitBucket as GitHub here as well, these are written by Atlassian, which makes a GitHub-like system called BitBucket)?

3. What branch is used as the basis of a feature branch in the GitFlow workflow? What branch or branches is a hotfix branch merged into in a GitFlow workflow?

4. How are pull requests used in the Forking workflow?

5. (Opinion) Which workflow is best for small teams? Which workflow is best for open-source projects with distributed contributors?

6. How many different changes should be in a single commit? Why?

7. What kinds of information should be in a commit message? Should it include details of the actual code modifications?
