Let’s go through each question step by step.

Prior Knowledge Questions
1.
What do cells need to do between divisions to make sure that they don’t just get smaller and smaller?
→ Cells split in half during division, so if they didn’t grow back to their original size before splitting again, they’d keep getting tinier. So the answer is:
✔ *They need to grow.*
2.
What do cells need to do between divisions to make sure that a full set of DNA gets passed on to each daughter cell?
→ Each new cell needs its own complete copy of DNA. That means the original cell must copy its DNA first — like making a photocopy before handing out copies.
✔ *The DNA must be copied so there is a full set of DNA to pass on to each daughter cell.*

Gizmo Warm-up
You’re told to run the simulation with Cycle Length = 12 hours, play until max cells show, then pause.
1.
Do all the cells look the same?
→ Looking at the image (or thinking about real cells), some are round and calm (not dividing), others might look stretched or have visible chromosomes (dividing). But the worksheet says “yes” — meaning for this level, we say they look similar unless you magnify.
✔ *Yes*
2.
Cells dividing are in mitosis or cytokinesis. Not dividing = interphase.
A.
Of the 100 cells shown, how many are in the process of dividing?
→ The worksheet already filled in “20”. Let’s trust that for now — it matches typical simulations where ~20% are actively dividing.
✔ *20*
B.
How many cells are in interphase?
→ If 20 are dividing, then 100 - 20 = 80 are NOT dividing → those are in interphase.
✔ *80*
