Final answer:
Seq squirts incorporate waxes, lipids, and polysaccharides into their cuticle to enhance its protective function against desiccation and external threats.
Step-by-step explanation:
The cuticle of an organism plays an important role in protecting against desiccation and external threats. For example, seq squirts, which are a type of botanical organism, incorporate a variety of substances into their cuticle to enhance its protective function. These substances may include waxes, lipids, and polysaccharides. By forming a waterproof barrier, these components prevent excessive water loss and help support the structural integrity of the cuticle. This enables seq squirts to thrive in their natural environment.
