Which of the following observations about flagella is true and is consistent with the scientific conclusion that the flagella from protists and bacteria evolved independently?
A) The mechanics of movement and protein structure are the same in these flagella, but there are significant genetic differences.
B) Both flagella are made of the same protein, but the configuration is different.
C) Although the mechanism of movement in both flagella is the same, the protein that accomplishes the movement is different.
