Question

determine whether the hypothesis was supported
hypothesis: if the mystery food is tofu, then it will react with the reagent that indicates the presence of a protein because tofu is primarily protein.
sample response: the mystery food sample did not test positive for protein using the biuret indicator, so the sample can not be tofu, which is what zack ate.
based on the data, was zack, who ate the tofu, guilty of leaving a mess in the classroom? no
justify your answer. the hypothesis focuses on the chemical property of tofu.
check all facts below that you included in your explanation.
zack ate tofu.
tofu contains a great deal of protein.
the mystery food sample tested negative for protein.

Explanation:

Step1: Identify tofu property

Tofu is high - in protein.

Step2: Analyze test result

Mystery food was negative for protein.

Step3: Draw conclusion

Since tofu should test positive for protein and mystery food didn't, the mystery food isn't tofu, so Zack is not guilty.

Answer:

• no
• Tofu contains a great deal of protein.
• The mystery food sample tested negative for protein.
