The correct answer is A. Provides body tissues with oxygen
Explanation:
The respiratory system includes different organs such as the lungs, diaphragm, trachea, etc. that allow organisms especially animals to exchange gases that are necessary to survive. This mainly occurs as oxygen is taken from air or water in the case of fish and other aquatic animals and this provides the body tissues with oxygen that is necessary for multiple processes and at the same time it takes out the carbon dioxide through exhalation. Considering this, it can be concluded the respiratory system provides body tissues with oxygen.

Explanation:
Climate change includes any change resulting from different factors, like deforestation or an increase in greenhouse gases. Global warming is one type of climate change, and it refers to the increasing temperature of the surface of Earth
Modern classification systems, based largely on molecular evidence, divide living organisms into three domains: Bacteria (also called Eubacteria), Archaea, and Eukarya. Plants are classified as a kingdom (Plantae) within the Eukarya; organisms that possess a <span>nucleus </span>,<span>mitochondria </span>, an internal <span>cytoskeleton </span>, and, in photosynthetic species, chloroplasts. Most scientists recognize three other eukaryotic kingdoms: Protista (most of which are single-celled organisms), Fungi, and Animalia (animals). The fungi, plants, and animals are thought to have evolved from different groups of protists.
Plants are multicellular organisms that have evolved the ability to live on land. The vast majority can carry out photosynthesis, but they are not the only organisms with this ability: many protists can photosynthesize too, as can several important groups of bacteria.
