A "Lab" is a controlled environment where scientific research, experiments, and measurements are conducted. It can be found in various fields, including biology, chemistry, and physics. Labs are equipped with specialized tools and equipment, such as microscopes, test tubes, and computers, to help scientists gather data and analyze results. In a lab, researchers follow strict protocols to ensure accuracy and safety. They may work on projects related to medicine, environmental science, or engineering. The findings from lab experiments can lead to new discoveries, innovations, and advancements in technology and health.
