Two atoms total are in NaCl.
Answer:
The correct option is: A. activity; concentration
Explanation:
A reaction rate essay is a laboratory method to determine the activity of an enzyme. It is necessary for determining the enzyme kinetics and inhibition.
Whereas, a colorimetric analysis is a method to determine the concentration of a chemical compound in a solution. Therefore, a colorimetric endpoint assay measures the concentration.
Therefore, Enzyme activity is measured by a reaction rate assay and the concentration is measured by a colorimetric endpoint assay.

A sustainable practice is B. Setting usage limits on a resource
<h2>Why? </h2>
Sustainable practices are those that aim to reach an equilibrium between the use of natural resources for human development, and the preservation of the environment for future generations.
Setting usage limits on a resource is a sustainable practice because it allows for taking advantage of the resource, while providing constraints to its use, forcing the industry to be creative and develop alternative methods that take better advantage of that resource, or that use different resources (e.g. limiting fossil fuel emissions, forcing the industry to find alternative ways to generate power like solar energy).
