PTC Tasting and Micro:bit Survey

The video tutorial explains phenyl thio carbamide (PTC), a lab-created molecule similar to bitter chemicals in broccoli. It discusses how the ability to taste PTC is genetically inherited and varies among individuals. The tutorial demonstrates how to conduct a survey to determine PTC tasting ability using both traditional methods and a Micro:bit device. It provides a detailed guide on programming the Micro:bit to collect and analyze survey data, including calculating the percentage of people who can taste PTC. The video encourages viewers to explore other traits and conduct similar experiments.
