a) Microanalysis and macroanalysis
b) Qualitative and quantitative analysis
c) Observation and deduction
d) Inspection and interpretation

Answer 1

Microanalysis and macroanalysis are the two methods used by forensic scientists when examining physical evidence. Microanalysis involves the examination of evidence at a microscopic level, while macroanalysis involves the examination of evidence on a larger scale.

Step-by-step explanation:

The two methods used by forensic scientists when examining physical evidence are microanalysis and macroanalysis.

Microanalysis is a technique that involves the examination of evidence at a microscopic level. It allows forensic scientists to analyze small particles, such as fibers, hairs, or microscopic organisms, to gather information that can be used in criminal investigations. For example, microanalysis can help determine the presence of trace evidence at a crime scene or identify the source of a biological sample.

Macroanalysis, on the other hand, involves the examination of evidence on a larger scale. This method allows forensic scientists to analyze physical evidence that can be seen without the need for magnification. Examples of macroanalysis include the measurement and comparison of tire tracks, fingerprints, and tool marks found at a crime scene.
