History

Which materials failure increases during sericulture if silkworms overheat?

A)Silk fibroin protein denatures
B)Mulberry leaf nutrients deplete
C)Cocoon strands become brittle
D)Exoskeleton chitin hardens abnormally

💡 Explanation

Silk fibroin denatures because elevated temperature disrupts hydrogen bonds responsible for its coiled structure; therefore its breaking strength substantially decreases, rather than resulting in issues like brittleness that affect secondary attributes.
