Question

Define stem cells.Compare and contrast stem cell and tumor cells.

Can you please address what did i violate

here? Every time i ask some questions comes up saying issue found and the violation of code. I think no one nor me will copy and paste your answer and submit to someone as my own work. I am asking to get help for my exam. So frustrating!!!!! Sorry.
