A negative feedback initiated by the external simuli or the products of a reaction aims to reduce the products/ output of the reaction. Hence In negative feedback the stimulus is reduced.

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.
