Question

Insects breathe through spiracles True or false

Answer 1

True.......................

Answer 2

HI MATE......

Insects, and some other invertebrates, exchange oxygen and carbon dioxide between their tissues and the air by a system of air-filled tubes called tracheae.

Tracheae open to the outside through small holes called spiracles.

The spiracles are guarded by:-

1.valves controlled by muscles that enables the grasshopper to open and close them;

2.hairs that filter out dust as the air enters the spiracles.

HOPE THIS MIGHT BE HELPFUL
