A deactivated deadly strain of bacteria was first treated with protease enzyme. It was then mixed with a harmless strain of live bacteria. The live bacteria became deadly. Which of the following statements is a valid conclusion from the experiment above?
a. Dead bacteria are more deadly than live bacteria
b. Protease enzyme causes live bacteria to become deadly
c. Killed bacterial components can make live bacteria deadly
d. Proteins are dangerous to live bacteria and kill them.
Is it B?
No, the valid conclusion from the experiment is option C: "Killed bacterial components can make live bacteria deadly." This is because when the deactivated strain of bacteria was treated with protease enzyme, the resulting killed bacterial components were able to transmit their deadly properties to the harmless live strain of bacteria, causing them to become deadly as well. Therefore, the experiment shows that the killed bacterial components are capable of making live bacteria deadly.
Yes, the correct answer is b. Protease enzyme causes live bacteria to become deadly.
To arrive at this conclusion, let's analyze the experiment and the options given:
- The experiment involves a deactivated deadly strain of bacteria being treated with protease enzyme. Protease enzyme is an enzyme that breaks down proteins.
- The deactivated deadly strain of bacteria, after being treated with protease enzyme, is then mixed with a harmless strain of live bacteria.
- The live bacteria, which were previously harmless, become deadly after being mixed with the treated deactivated bacteria.
Based on this experiment, we can conclude that the protease enzyme, which breaks down proteins, causes the live bacteria to become deadly. This suggests that the protease enzyme somehow activates or modifies the proteins in the deactivated bacteria, making them lethal to the live bacteria.
Therefore, option b. Protease enzyme causes live bacteria to become deadly, is the valid conclusion from the experiment above.
