Question

an athlete bought a sport gel food and wanted to test it to see if it contained fats, starches, and glucose. the tests that the student used are shown in the table below.
what is in the sports gel?
a. fat, starch and glucose are in the sports gel.
b. only fat and starch are in the sports gel.
c. only starch and glucose are in the sports gel.
d. none of these are in the sports gel.

Explanation:

Step1: Analyze the test for fat

A positive test for fat shows a greasy paper. The student's result for fat is a non - greasy paper (negative result), so there is no fat in the sports gel.

Step2: Analyze the test for starch

A positive test for starch shows a blue - black color. The student's result for starch is blue - black (positive result), so there is starch in the sports gel.

Step3: Analyze the test for glucose

A positive test for glucose shows a brick - red/orange color. The student's result for glucose is brick - red/orange (positive result), so there is glucose in the sports gel.

Since there is starch and glucose in the sports gel, option A is correct.

Answer:

A. Fat, starch and glucose are in the sports gel.
