A.Students should wash their hands after mixing chemicals in the laboratory. B.Students should inform the teacher immediately of any accidents or spills in the laboratory. C.Students should use cracked glassware only when the teacher is in the laboratory. D.Students should read instructions thoroughly before performing laboratory procedures. A.Students should wash their hands after mixing chemicals in the laboratory. B.Students should inform the teacher immediately of any accidents or spills in the laboratory. D.Students should read instructions thoroughly before performing laboratory procedures To prevent accidental ingestion or absorption of potentially harmful substances, students should wash their hands after working with chemicals. To help maintain a safe environment, accidents and spills in the laboratory should be reported to the teacher immediately so that a correct response can be implemented. To safely and effectively complete laboratory procedures, students should read instructions thoroughly before starting the procedures. Cracked glassware is a safety hazard and should never be used. Which of the following processes most directly involves the movement of water from the atmosphere to Earth's surface? A.Infiltration B.Precipitation C.Transpiration D.Sublimation B.Precipitation Precipitation is the process by which atmospheric water falls to Earth's surface in the form of rain, hail, sleet, or snow. Because atmospheric water returns to Earth's surface primarily through the process of precipitation, it is an important part of the water cycle. Infiltration is the process by which water on Earth's surface enters the subsurface soil and rock. Transpiration is the process by which water evaporates from plant leaves and enters the atmosphere. Sublimation is the process by which a substance transitions directly from the solid phase to the gas phase without going through the liquid phase. Which of the following is an important function of the digesti
