Question
Cryo preservation techniques involves by using*2 pointsLiquid sulphurLiquid NitrogenLiquid chlorineDry ice
Solution
Cryo preservation techniques involve the use of Liquid Nitrogen. Here are the steps:
-
Sample Preparation: The biological material to be preserved is prepared. This could be cells, tissues, or even whole organisms. The preparation often involves placing the material in a solution that will protect it from damage during freezing and thawing.
-
Cooling: The prepared sample is then cooled to very low temperatures, typically using liquid nitrogen. This is done slowly to prevent the formation of ice crystals which can damage the material.
-
Storage: Once the sample has been cooled to the appropriate temperature, it is stored in a cryo preservation unit. This keeps the sample at a constant low temperature, typically -196 degrees Celsius, the boiling point of liquid nitrogen.
-
Thawing: When the material is needed, it is carefully warmed up to room temperature. This is done slowly to prevent damage from rapid temperature changes.
-
Recovery: After thawing, the material is often placed in a suitable environment to recover. For cells, this might be a nutrient-rich culture medium.
So, the correct answer is Liquid Nitrogen.

In the remote ice fields of Greenland, glaciologists have uncovered evidence of microorganisms living within the ice, which possess unique biochemical mechanisms allowing them to metabolize sulfur compounds in extremely low temperatures. This discovery, led by Fiona Zheng, contradicts the long-held assumption that microbial life could not sustain metabolic activities in such harsh, cold environments. Utilizing advanced cryo-electron microscopy and isotopic analysis, Zheng's team demonstrated that these microorganisms play a crucial role in the ice's sulfur cycle, a finding that significantly alters our understanding of biogeochemical cycles in polar regions. Considering the unique adaptations of these microorganisms, Zheng proposed that ______15Mark for ReviewABCWhich choice most logically completes the text?Athe metabolic processes of these microorganisms are less efficient in cold environments compared to those in temperate regions, indicating a limitation in the diversity of life forms that can exist in polar ice fields.Bthe reliance on sulfur compounds for metabolism by these microorganisms suggests that sulfur may be more abundant in Greenland's ice fields than previously thought, requiring a reevaluation of the chemical composition of polar ice.Cthe discovery of these microorganisms indicates a need to reassess the impact of global warming on polar ecosystems, as the melting ice could release trapped microorganisms and alter global sulfur cycles.Dthe existence of sulfur-metabolizing microorganisms in Greenland's ice fields suggests that life can adapt to and thrive in more extreme conditions than previously believed, expanding the potential habitats for microbial life on Earth.
