Extremophilic bacteria are able to survive in hostile environments,including scalding hot water as well as springs and vents that reach temperatures over 100°C.Researchers studying these bacteria measured the function of a protein from an extremophile bacterium at 100°C,and they also measured the function of a similar protein from a human cell at 100°C.Which of the following results do you think the researchers obtained?
A)The bacterial protein functioned normally,whereas the human protein did not.
B)The human protein functioned normally,whereas the bacterial protein did not.
C)The bacterial protein and the human protein both functioned normally.
D)Neither the human protein nor the bacterial protein functioned normally.

Extremophilic bacteria are adapted to survive in high temperatures, while human cells are not. Therefore, it is likely that the protein from an extremophile bacterium would function normally at 100°C, while the protein from a human cell would not.
