Hi dude....

The correct option is (1) LIQUID NITROGEN.

HOPE THIS HELPS...

Answer 2

Cryopreservation means storing products in (1)Liquid nitrogen.

Cryopreservation:

• Cryo-preservation, also known as cryo-conservation, is the act of freezing organelles, cells, tissues, extracellular matrix, organs, or any other biological constructions that are susceptible to harm caused by unregulated chemical kinetics.
• Cryopreservation is a method of preserving organelles, cells, tissues, or other biological constructions by freezing them at extremely low temperatures.
• The responses of live cells to ice formation are both theoretically and practically interesting.
• A controlled-rate freezer is used in the majority of cellular cryopreservation systems.
• This freezing mechanism injects liquid nitrogen into a closed chamber containing the cell suspension.
• The sample is typically stored at -196°C.
• All biological activity of the cells ceases at such low temperatures, and the cell dies.
• Unprotected freezing is typically lethal, and this chapter aims to examine some of the mechanisms at work and demonstrate how cooling can be employed to create stable conditions that save lives.
