Answer 2

$\bold \blue{i)}$

Air enters the respiratory systems of insects through a series of external openings called spiracles. These external openings, which act as muscular valves in some insects, lead to the internal respiratory system, a densely networked array of tubes called tracheae

$\bold \red{ii)}$

Skeletal structure surrounding chest cavity. Ribs and sternum together forms a rib cage that surrounds the chest cavity. It protects the internal organs such as heart from mechanical shock and injury.

$\bold \pink{iii)}$

The diaphragm, located below the lungs, is the major muscle of respiration. It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity cavity enlarges

$\bold \green{iv)}$

Stomata (noun, “STO-mah-tah”, singular “stoma”) These are the small pores in plant stems or leaves that allow carbon dioxide in and oxygen and water vapor out. Each tiny hole is surrounded by a pair of cells called guard cells. These cells control whether a stoma is open or closed

$\bold \orange{v)}$

Air enters the respiratory systems of insects through a series of external openings called spiracles. These external openings, which act as muscular valves in some insects, lead to the internal respiratory system, a densely networked array of tubes called tracheae

$\bold \red{vi)}$

The respiratory system consists of all the organs involved in breathing. These include the nose, pharynx, larynx, trachea, bronchi and lungs.

$\bold \blue{vii)}$

When we inhale air, it passes through our nostrils into the nasal cavity. From the nasal cavity, the air reaches our lungs through the windpipe. Lungs are present in the chest cavity (Fig. 10.4)

$\bold \green{viii)}$

An anaerobic organism or anaerobe is any organism that does not require oxygen for growth. It may react negatively or even die if free oxygen is present. In contrast, an aerobic organism is an organism that requires an oxygenated environment. Anaerobes may be unicellular or multicellular. 

$\bold \orange{ix)}$

Cockroach is an organism which has a tracheal system.
