Final answer:
The Frozen Zoo is a conservation facility that stores the frozen cell lines of different animal species to preserve their genetic material for future use.
Step-by-step explanation:
The frozen zoo refers to a conservation facility where the cell lines of various animal species are stored. These cell lines typically include sperm, eggs, embryos, and genetic material, which are preserved in a frozen state through deep freezing techniques. The cells are frozen using a method called cryopreservation, which allows them to be stored for long periods at very low temperatures.
The process involves adding nutrients for energy, a protectant to avoid damage during cooling, and a buffer to maintain pH levels. This method of preservation halts the metabolic activity of these cells without affecting their viability, allowing for potential future use in reproduction and conservation efforts.
