Biochemistry is the study of the chemical processes and substances that occur within living organisms. It focuses on the structure, function, and interactions of biological molecules such as proteins, nucleic acids, carbohydrates, and lipids. Biotechnology, on the other hand, involves the use of living organisms or their components to develop products and processes for various applications, such as medicine, agriculture, and industry. It often involves genetic engineering, fermentation, and other techniques to manipulate biological systems. Molecular biology is a branch of biology that focuses on the structure and function of macromolecules essential to life, such as DNA, RNA, and proteins. It seeks to understand the molecular basis of biological processes and often involves techniques such as DNA sequencing, cloning, and gene expression analysis. **

The Eufy G10 Hybrid can be used for mopping by attaching the mopping module to the robot vacuum. The mopping module has a water tank and a mopping cloth that can be filled with water and attached to the bottom of the vacuum. Once attached, the vacuum can be programmed to mop specific areas or entire rooms, and it will navigate around obstacles while mopping. The mopping cloth will dampen and clean the floor as the vacuum moves, providing a convenient and efficient way to keep floors clean. **

To use the Eufy G10 Hybrid for mopping, you first need to attach the mopping module to the robot vacuum. Fill the water tank with clean water and attach it to the mopping module. Then, select the mopping mode on the EufyHome app or on the robot vacuum itself. The robot will then navigate your home and mop the floors, leaving them clean and shiny. **
