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.
Answer:
(a) The arrangement of metals in a vertical column in the order of decreasing reactivities is called reactivity series. The reactivity series follows the order:
Answer: (c) a gold brick would have the least amount of inertia.
The inertia of an object refers to its ability to continue in its present state of rest or uniform motion until any external force act of the body to change its state of motion.
The inertia of a body increases with its mass. For this reason, a body with more mass and high inertia needs larger force to change its state of motion or rest. Among the given objects, the mass of a gold brick is the least. For this reason, it would have the least amount of inertia and least amount of force is required to change its state of motion or rest.
Mabye smnsieneshe then i waitbsne ndjsnahhe. yahahahha
