This question is incomplete
Step-by-step explanation:
This question is incomplete and hence makes it difficult to be accurate because of the absence of options. However, for the first blank space, what human cells have in common (with each other in the same body) is the genetic composition thus it can be said that regardless of the the type of cells, almost all of them have the same DNA or genes. However, presence of the same DNA does not mean they carry out the same function. This is as a result of a process known as differentiation.
