Question

chemistry are the two analytical branches that are important to forensic chemistry.
organic and inorganic
spectrometry and spectrographic
qualitative and quantitative
physical and atomic

Explanation:

• Qualitative analysis in chemistry determines the presence or absence of substances.
• Quantitative analysis measures the amount of substances.
• Both are crucial in forensic chemistry for identifying and quantifying evidence (e.g., drugs, toxins).
• Organic/inorganic is about carbon - containing vs non - carbon - containing compounds (not the key analytical branches here).
• Spectrometry/spectrographic are techniques, not main analytical branches.
• Physical/atomic is not the relevant pair for general analytical branches in this context.

Answer:

Qualitative and quantitative
