Answer 1

Answer: d.  All the body cells arise from mitotic divisions of the same fertilized egg.

Explanation:

After conception occurs and an egg is fertilized, mitosis takes place as the egg begins to divide into other cells. This is how all the cells in the body are eventually formed regardless of how specialized their roles are.

As a result, every cell in the human body shares the same genes so any biological liquid or structure of the body would indicate the criminal because they would share the same gene as the rest of the cells in the criminal.
