Scenario Questions

After reading the following paragraph, answer the question(s) below.

You're the manager of a factory that produces enzyme-washed blue jeans (the enzymes lighten the color of the denim, giving a "faded" appearance). When the most recent batch of fabric came out of the enzyme wash, however, the color wasn't light enough to meet your standards. Your quality control laboratory wants to do some tests to determine why the wash enzymes didn't perform as expected.

1)

Which hypothesis is most likely to be productive for their initial investigation?
A)

The nucleotide chain of the enzymes may be incorrectly formed.
B)

The dye in the fabric may have hydrolyzed the fatty acids in the enzymes.
C)

The polysaccharides in the enzymes may have separated in the wash water.
D)

The three-dimensional structure of the proteins may have been altered.
E)

There may not have been enough phospholipids for the volume of fabric.
