Question 2

An organism's stem cells can transform into brain cells, blood cells, muscle cells, or any other specialized cell found in the organism. Planarian worms have an extremely high stem cell count throughout their bodies.

a
a planarian worm's cells can never truly die
b
planarian worms can adapt to any environmental changes

planarian worms are able to evolve faster than other organisms
