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 galaxies closer to earth would be older than earth, galaxies close to earth would be about the same age as the Milky Way which is much older than the earth. The earth did not form at the same time as the Milky Way was formed
Answer:
The two forms interbreed and their offspring survive and reproduce well.
Explanation:
When talking about classification of species, one of the first features observed is the species fitness, which describes the reproductive success or their ability to leave to their successive generations the most copies of their genotype. When different species that were recently divided into 2, by geographic isolation, for instance, usually there is no genetic compatibility, and if its possible to produce offspring, there might be some development issues like infertility.
Answer:
E. Carbon, helium, nitrogen, oxygen, phosphorus, sulfur, or, as some prefer to call them,
CHNOPS.
or
D. Carbon, hydrogen, nitrogen, oxygen, phosphorus, sulfur, or, as some prefer to call
them, CHNOPS
Answer:
<h3>The peppered moth was originally pale in color, but eventually evolved into a darker form when the air pollution of the Industrial Revolution caused tree bark to darken with soot and lichen was killed off. As lichen recovered and levels of soot in the atmosphere went down, the species turned pale again.</h3>
