An investigator has a strong suspicion that a hair sample from a suspect will match one found at the scene of a crime. To reliably and efficiently show the samples match, the investigator would turn to: unaided vision. microscopic analysis. DNA analysis. morphology analysis.

## Step 1<br />The problem presents a scenario where an investigator suspects that a hair sample from a suspect will match one found at the crime scene. The investigator needs to find a reliable and efficient method to confirm this suspicion.<br /><br />## Step 2<br />The options provided are unaided vision, microscopic analysis, DNA analysis, and morphology analysis. <br /><br />## Step 3<br />Unaided vision and microscopic analysis can reveal some details about the hair, such as its color and texture. However, these methods are not as reliable or efficient as DNA analysis.<br /><br />## Step 4<br />Morphology analysis, which involves the study of the form and structure of organisms and their specific structural features, can provide some information about the hair. However, it is not as definitive as DNA analysis.<br /><br />## Step 5<br />DNA analysis is the most reliable and efficient method among the options provided. It can provide a definitive match between the hair samples, as each individual's DNA is unique (except for identical twins).
