Plant And Animal Specimens In Jars Containing Liquid Preservative
Explanation
D: Plant and animal specimens in jars containing liquid preservative.
This is because liquid preservatives can help to maintain the structure and appearance of the specimens for a longer period of time. The liquid preservative can also prevent decay and deterioration of the specimens, which is important for the preservation of scientific and educational collections.
Preserving plant and animal specimens in jars with liquid preservatives is a common practice in natural history museums, where they are used for scientific research, education, and display. These preserved specimens can provide valuable information about the diversity, morphology, and ecology of different species, as well as their geographic distribution and evolutionary relationships.
Additionally, many museums have guidelines and ethical standards for the collection and preservation of specimens, including obtaining permits for collecting specimens, minimizing harm to living organisms, and ensuring that the specimens are collected and preserved in a responsible and sustainable manner.
