What about cellouse makes it ideal for structural support

Due to the strong intermolecular force of attraction in cellulose it provides high strength and support.

Cellulose is a significant polysaccharide since it is the most copious natural compound on Earth. Cellulose is a significant segment of intense cell dividers that encompass plant cells, and it's what makes plant stems, leaves, and branches so solid. It absolutely takes a ton of effort to cause damage to the structure of cellulose.  

Cellulose particles are arranged parallel to one another and are combined with hydrogen bonds. This structures long, link like structures, which join with other cellulose atoms and is the thing that produces such a solid help structure.

not the best question format lol but what i think might as scale color is controlled by a single gene with two alleles, the green allele and the yellow allele. when moths that are homozygous for green scales are mated with moths that are homozygous for yellow scales, 100% of the offspring have green scales.
