BHuman
CFish
DCockroach
Answer:
D. Cockroach
Read Explanation:
Out of the options provided, cockroaches are the organisms that have spiracles, which are small openings on their bodies that allow air to enter their respiratory system.
Out of a typical set of biological options that might be provided (e.g., mammals, birds, fish, amphibians, reptiles, insects, etc.), cockroaches are indeed organisms that possess spiracles as part of their respiratory system.
Spiracles are external respiratory openings found on the exoskeleton of insects and some other arthropods.
These openings lead to the internal tracheal system, a network of tubes that delivers oxygen directly to the tissues and cells of the insect's body.
