Answer:
The correct answer is - Benedict's solution for the test for glucose in food.
Explanation:
Benedict's solution is a test that is used to check if there is a presence of glucose in a food sample or not. It is possible due to the oxidation of the aldehyde present in the glucose turns to carboxylic acid in presence of the clear blue solution of sodium and copper salts or benedict's solution.
In presence of Benedict's solution the color of the sample turns yellow to orange with an increase in heat, however, the initial color of the solution is aqua blue.
Thus, the correct answer is - Benedict's solution for the test for glucose in food.

Answer:
- law of superposition - Relative Dating
- important method for geologists - Absolute Dating, Relative Dating
- places historical events in their correct order - Relative Dating
- establishes how many years ago a given event took place - Absolute Dating
- radioactive decayused on rock strata - Absolute Dating
Explanation:
Absolute dating is an important process used by geologists. This process allows geoologists to determine the timing of a given factor in the environment. In other words, absolute dating allows a numerical age to be estimated for that factor or the age interval between factors, but without putting the factors' formation events in order. It is generally used to date chemical and physical elements present in artifacts and rocks.
Relative dating is also an important process for geologists, but it does provide a relative order of past events and does not provide a numerical age, like absolute dating. It is generally used to date rocks, surface deposits and fossils, often using the law of superposition as a basis.
