Correct Answer: B. clusters of nerve cell bodies coordinating segmental functions
Explanation:
Ganglia act as local control centers. Insects can coordinate segmental movements through thoracic and abdominal ganglia, sometimes even with partial independence from the brain.
Correct Answer: C. brain and ventral nerve cord coordinate behavior
Explanation:
The insect nervous system includes a brain and a ventral nerve cord with ganglia. It controls sensory processing, movement, feeding, and reproductive behaviors.

Correct Answer: C. fluid that transports nutrients, hormones, wastes, and immune cells
Explanation:
Hemolymph is the circulating fluid of insects. It supports transport and immunity, but oxygen transport is usually handled mainly by the tracheal system.
