Answer:
In animals, the process of respiration is aerobic respiration, exchange of gases takes place ( carbon dioxide leaving the cell, oxygen entering)
Single cellular organisms can exchange gases directly across their cell membrane through the process o diffusion.
Large animals cannot maintain gas exchange by diffusion across their outer surface. A respiratory surface is covered with thin, moist epithelial cells that allow oxygen and carbon dioxide to exchange. Those gases can only cross cell membranes when they are dissolved in water or an aqueous solution, thus respiratory surfaces must be moist.

Answer:
The correct answer is- Prokaryotic
Explanation:
There are two types of cell prokaryotic and eukaryotic. A prokaryotic cell is the cells that do not have a nucleus and other membrane-bound organelles while a eukaryotic cell has a well membrane-bound nucleus and other membrane-bound organelle.
As prokaryotic cells do not have nucleus so their genetic material is present in the cytoplasm of the cell while eukaryotes have their genetic material inside their nucleus. Organisms having prokaryotic cells are called prokaryotes and those organisms who have eukaryotic cells are called eukaryotes.
