I’m working on a biology writing question and need an explanation and answer to help me learn.

1. Use the following citation to address the following questions:
   1. What are human organoids and what are they used for? 
   2. How are human organoids generated? Cell origin and experimental process 
   3. Find an example of a human organoid experiment that is of interest to you; provide a citation for this example
