How does coughing and sneezing help protect the respiratory system?
andriy [413]
Coughing and sneezing are reflexes of the body that prevent bacteria to further damage the organs inside the body. It helps in keeping the airways clear and in healing. The two sources or passages of these natural reflexes are the nose and the mouth.  
<span>
Inside the nose, there are nasal hairs present to filter the oxygen or air that we breathe in. These are called Cilia, these are protective mechanisms of the body that trap dirt that cannot pass through the respiratory system. Sneezing is a natural reflex that clears the nose passages from obstructions that might affect the lungs. Coughing is also a natural reflex that is generated by an irritation in the tonsils, this condition is commonly viral. The tonsils are responsible for protecting the passage of dirty air into the lungs.</span>

<h2>Wet versus Dry habitats</h2>

Explanation:

  • Plants from wet habitats have a relatively large number of stomata and thin cuticle
  • Plants from dry habitats have a less number of stomata and thick cuticle
  • Stomata helps in exchange of gases whereas cuticle reduces the loss of water
  • If water is more then plants have large number of stomata which helps in great access to water and increases support for herbaceous tissues
  • In case of dry habitat conditions are not favorable with regard to water hence a thick cuticle is required to minimize the water loss while in wet habitat water is abundant hence they have a thin cuticle

A.Vascular plants have a relatively large number of stomata
