are there other tests that could be used to determine if cyclohexanol is present in your product? give at least one test with so
Artist 52 [7]

One of the many tests that may be used to identify the presence of cyclohexanol in a product is that of the Lucas test.

The Lucas test is a chemical reactant test to determine the presence and level of alcoholism in a solution.  Cyclohexanol has many chemical properties as do most substances, one of which is the presence of an alcohol group.

The presence of this chemical group makes it possible to test for cyclohexanol using the Lucas test. The Lucas test will cause reactions in the presence of alcohol and transform alcohols into chloroalkanes, which tend to be nearly insoluble in aquatic solutions. Given this, a <u>positive result </u>will look like <em><u>the solution separates into a cloudy chloroalkane-containing part on top of a much clearer layer.</u></em>

If you were a scientist studying traits which are selected by humans instead of the environment, you would be studying the follo
Dvinal [7]

The correct answer is: Artificial selection (selective breeding).

Artificial Selection is a form of selection, totally influenced by human, in which traits that should be passed onto offspring are chosen by human. Selective breeding was used long before the genetics was discoverd. Farmers used individuals with beneficial traits, larger in size, with bigger fruit etc.

Hunting is also one type of selective breeding, since the hunters choose the animal and remove it from the population (gene pool), leaving the “weaker” to pass on to the next generation.
