True or false? A beavers teeth are so strong because they have copper in cells of their tooth enamel.
False- their tooth enamel actually has IRON in it! (This is also why their teeth look orange!)
What does the M in PMC stand for?
Metabolism
What organelle converts food into energy for the cell?
Mitochondria
What is special or different about HeLa cells compared to regular cells?
HeLa cells continuously divide which allows them to multiply and be kept alive in labs for a long time.
TRUE or FALSE: Henrietta Lacks gave her doctors permission to take a sample of her tumor and study her cells.
FALSE
True or false?
A penguin’s throat is lined with smooth, slippery muscle tissue, allowing it to swallow whole fish easily.

What is a chromosome?
Organized DNA within the nucleus
What are TWO MORE scientific advancements or discoveries (besides the polio vaccine) that HeLa cells helped bring about?
-studying viruses
-treat/study diseases (measles, HIV, ebola)
-study cloning, genetics

TRUE or FALSE: Henrietta Lacks and her family knew about her unique cells and their contribution to science.
FALSE
What is the animal that can only be seen under a microscope, and that can survive almost any environment, including being exposed to extreme temperatures, being frozen for thousands of years in ice, and being sent through the vacuum of space?
Tardigrades. The microscopic tardigrade can suspend its metabolism in difficult times to survive extreme circumstances!
