The statement that the integument is strictly composed of the skin and It does not include the various accessory structures that may be present on or beneath the skin layers is False.
<h3>Composition of integument</h3>
- Together with the underlying epidermal cells that secrete the cuticle, the cuticle and integument make up the skin.
- The cuticle functions as the insect's exoskeleton, the location of muscle attachment, and the first line of protection against fungi, bacteria, predators, parasites, and environmental toxins, including pesticides.
- The integument plays a role in behavior, osmoregulation, water control, eating, excretion, desiccation resistance, and as a food reserve.
- The complexity of the structure and chemistry of an insect's integument as well as the unique ways in which it has been modified to work within its owner's environment serve as some indicators of the variety of roles that these coverings play.

The answer is option C. Number of double covalent bonds between carbon atoms is responsible for causing different shapes of saturated and unsaturated fatty acids. The double covalent bond causes kink in the unsaturated fatty acids because of which their stacking is disrupted and they become loosely packed. The problem with double covalent bond is that unlike single covalent bond it can't rotate and has almost cis-configuration. This is also the reason behind their liquidity at room temperature.
Mutations can occur before, during, and after mitosis and meiosis. If a mutation occurs in cells that will make gametes by meiosis or during meiosis itself, it can be passed on to offspring and contribute to genetic variability of the population
