Specimens are available for use in a wide variety of organic and inorganic testing procedures. Organic samples can be utilized for dissection purposes or studying whole preserved or life specimens, with practical examples in cellular biology or the internal structures of whole organs and complex multicellular systems. Rock specimens are useful for studying textures, grain sizes, and other features brought about by pressure, temperature, and other natural forces, offering a glimpse into the Earth’s geological history.
