A student is measuring the effect of different temperatures on the effect of enzymes in biological systems. What temperature ran
viktelen [127]

Answer:

A. 25 °C, 30 °C, 35 °C, 40 °C, 45 °C  

Explanation:

Each enzyme has a temperature at which it works best. In humans and many animals, that temperature is around body temperature (37 °C or 98.6 °F). Most enzymes are denatured and work poorly at 40 °C (104 °F).

That automatically eliminates Option B.

I would pick a temperature close to 37 °C (98.6 °F) and temperatures at intervals above and below that.

Option D is wrong because it includes no temperatures above body temperature.

Option C is wrong, because it includes temperatures of 45 °C and 55 °C, at which the enzymes will be denatured.

That leaves Option A as the best answer. It includes only one temperature above 40 °C.

Then we will choose the tag for the organism which is humans in this case. Then we will select the tag for the protein which is made by the nucleotide sequence, which is protein in this case. Hence, option A is the correct answer.
