Answer 1

If you were designing a new insecticide absorbed via the respiratory system in arthropods, the killing chemical would enter the invertebrate through the Tracheae.

• The tracheae, which extend inward from the spiracles and typically divide into smaller branches with a diameter of 2 microns or less, are the tracheal system's largest tubes. Since tracheae are made of ectodermal tissue, they contain a cuticular lining that is shed with each moult.

• The respiratory system of insects is distinct from the circulatory system, and gas exchange occurs through a network of internal tubes called tracheae.

• Every cell in the body receives oxygen-containing air thanks to a sophisticated network of tubes. Through holes that resemble valves in the exoskeleton, air enters the insect's body.
