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.

Which of the following human activities would be expected to be the biggest contributor to air pollution? a. driving b. restaura
Ulleksa [173]
A. driving. A single instance of a nuclear weapon would cause more pollution than a single instance of driving, but while millions of cars drive everyday, nuclear weapons are very rarely detonated. All the cars in the world contribute the most to pollution, especially because some countries still don't regulate the pollutants in exhaust.
