9. Which example best illustrates how integrated omics (genomics, transcriptomics, and proteomics) can support the development of stress-resilient seeds in a climate change context?

 Identifying genetic variants, expression patterns, and protein changes associated with drought-tolerant germination

 Using only visual scoring of seed color to select for drought tolerance

 Relying solely on historical yield data to choose varieties for future climates

 Measuring only final grain yield in multi-location trials without any molecular analysis

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