What process involves systematically cutting something for analysis?

The process of systematically cutting something for analysis is best described by the term "dissect." Dissection involves carefully separating or cutting apart various components to study their structure, function, and relationships, which is essential in fields like biology, forensic science, and even certain investigative aspects of law enforcement when examining evidence.

Dissecting allows for a detailed examination of materials, which can lead to a deeper understanding of the underlying factors or causes. This methodical approach is critical when accuracy and thoroughness are paramount, such as analyzing physical evidence in an investigation.

The other terms do relate to different processes, but they do not accurately capture the specific and systematic nature of cutting for analytical purposes. For instance, "prep" refers more generally to preparing materials for an analysis rather than the act of cutting itself. "Review" typically means to assess or evaluate something, and "break down" suggests a more general disassembling rather than the precise, methodical examination that dissection implies. Therefore, "dissect" is the most appropriate term to describe the systematic cutting for analysis.
