Mitosis: How Cells Divide.
🎯 Your mission
Run the experiment. Find out what really happens.
⚡ The twist
What the body does in one minute is wilder than any cartoon.
Mind = Blown
🦠 You have more bacterial cells in your body than human cells.
Make a hypothesis first
Guess: how does the body solve this problem?
