Final answer:
Artifacts are sorted, cleaned, and bagged with special attention to temperature, moisture levels, and degradation prevention.
Step-by-step explanation:
The artifacts are sorted, cleaned, and bagged with special attention to temperature and moisture levels in storage areas. Organic artifacts such as wooden canoes or human remains are prone to degradation and need to be properly stored and controlled. Ancient organic collections may require chemical stabilization to prevent further decay. Organic objects sealed away from air require permanent freezing or preservation with ammonium glycol.
