Unit 7A Pt1 - Mitosis

​HS-LS1-4: Use a model to illustrate the role of cellular division (mitosis) and differentiation in producing and maintaining complex organisms.

Multiple Choice

In mitosis, the two resulting cells are

• different from the starting cell and identical to each other.

• different from the starting cell and different from each other.

• identical to the starting cell and different from each other.

• identical to the starting cell and identical to each other.

Multiple Select
