Explanation

In humans and higher animals, the exchange of gases (oxygen and carbon dioxide) is carried out by the respiratory processes, which include:

• Breathing (inhalation and exhalation)
• Transport of gases through the blood
• Exchange of gases in the lungs (oxygen in, carbon dioxide out)

Explanation

• The ozone layer is a layer of gas in the stratosphere that contains a high concentration of ozone (O3).
• It absorbs most of the sun's ultraviolet (UV) radiation, protecting the Earth from harmful UV rays.
