9.

In a smart seed processing facility, computer vision and AI are used to sort seeds on a conveyor in real time. Which task is most realistic and impactful for such an AI-based sorting system?

 Inferring complete genomic sequences of each seed solely from its image

 Classifying and removing damaged or discolored seeds to improve lot quality

 Automatically adjusting the crop’s fertilizer schedule several months later

 Predicting next season’s market price based on seed shape

10. In cereal seeds, the primary function of the aleurone layer during germination is to __________
