Glass bottles can shatter at temperatures below freezing, typically around -15 to -20 degrees Celsius (5 to -4 degrees Fahrenheit). When the liquid inside the bottle freezes, it expands, exerting pressure on the glass walls. This pressure can cause the glass to crack or shatter. It is important to handle glass bottles carefully in cold temperatures to prevent breakage. **

Embryonic stem cells are derived from embryos and have the potential to develop into any type of cell in the body. Omnipotent stem cells, also known as pluripotent stem cells, are similar to embryonic stem cells in that they can differentiate into any type of cell, but they are derived from adult tissues. Adult stem cells are found in various tissues and have the ability to differentiate into a limited range of cell types. Totipotent stem cells have the highest potential for differentiation and can develop into any type of cell, as well as into extraembryonic tissues such as the placenta. Multipotent stem cells can differentiate into a limited number of cell types, typically within a specific tissue or organ. **
