See Android Developers page on Fragments

Answer 3

In Android an Activity can contain several Fragments inside. Each Fragment can be considered a View Controller. Android allows you include child Fragment inside parent Fragment.

When Activity is running, you can manipulate each Fragment independently, such as add or remove them.

Developer's documentation:

A fragment must always be hosted in an activity and the fragment's lifecycle is directly affected by the host activity's lifecycle. For example, when the activity is paused, so are all fragments in it, and when the activity is destroyed, so are all fragments.
