Final answer:
The true statement about American roaches is that they are one and a half to 2 inches in length. They prefer moist environments and have mouthparts designed for chewing, which differentiates them from other insects like butterflies with sipping mouthparts.
Step-by-step explanation:
The correct statement about American roaches is c) one and a half to 2 inches in length. American roaches, which are among the Hexapoda class that includes insects such as ants, beetles, and butterflies, are relatively large in size and prefer moist environments rather than hot dry environments. They do not typically possess stripes on their wings and are not commonly found in home attics, as these areas are not the ideal habitat for their survival. The design of an insect's mouthparts, including those of cockroaches, is reflective of their lifestyle. Cockroaches have mouthparts designed for chewing solid food, which is in contrast to butterflies that have a proboscis adapted for sipping nectar. This difference illustrates the diversity in diet and behavior among insects.
