Step-by-step explanation:
The question posed by the student concerns the practice of scanning barcodes on price cards at stores. It is okay for stores to scan barcodes on price cards. Mainly, because it assists with two key operations: firstly, it helps with inventory tracking, ensuring that stock levels are monitored correctly and efficiently, facilitating better supply chain management. Secondly, it helps to speed up the checkout process, allowing for a shorter waiting time for customers and a more streamlined payment procedure. While it may occasionally cause pricing errors, these are usually due to incorrect data entry or outdated information, rather than the scanning process itself. Therefore, the regular practice is both recommended and commonplace in retail environments.
Regarding Dr. Hebert's aspiration, it relies on the same principle of unique identifiers; where UPC barcodes are unique to each product, DNA barcodes are unique to each species. The comparison between these two systems can indeed help in understanding the concept of DNA barcoding because both systems rely on scanning a code to retrieve detailed information about an item, be it a grocery product or a living organism.
