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>

Your friend will talk about the definition of evolutionary medicine, and there by understanding the health and diseases
Explanation:
- Evolutionary medicine is the understanding the health and diseases using the evolutionary theory
- Evolutionary theory gives an idea of the heritable and morphological changes in the organism.
- Today, the field of research on evolutionary medicine is advanced to the molecular and psychological mechanism of health and diseases.
- Hence, your friend will talk about the evolutionary understanding of the health and diseases from the lens of the evolution of species. To create an understanding of the evolutionary medicines there need to ab understanding of the heath and diseases of previous ages.

<span>the large population becomes smaller.
also, bottleneck is when a large population quickly shrinks. the effects of genetic drift becomes much stronger.
e.g: seals
alleles can be lost during bottleneck and the number of alleles left can shift dramatically in just a few generations.</span>
