The deserts have a very varied location and are characterized by very sparse vegetation. The soil is very arid and the rainfall is low and irregular, below 250 mm of annual water. During the day the temperature is high, but at night there is rapid heat loss that radiates into the atmosphere and the temperature becomes excessively low.

Viruses are beings that do not have cells, they are constituted by nucleic acid that can be DNA or RNA, surrounded by a protein envelope called capsid. They are about 0.1µm in diameter, with dimensions only observable under the electron microscope. Because they are so small, they can invade cells, including unicellular organisms such as bacteria.
A characteristic common to all living beings, according to evolutionary theories, is the capacity for evolution. The evolution of living beings is the process of the disappearance or emergence of new species due to genetic variability. This process is very slow and can take up to thousands of years so it is difficult to keep up with the evolution process.
Diseases caused by parasitic protozoa basically involve two parasitism sites: the blood and the digestive tract. However, the skin, the heart, the organs of the genital system, and the lymphatic system are also places where parasites can settle. These diseases involve hosts in their cycle, that is, living organisms in which parasites thrive.
As a consequence of these disruptions, the oceans also suffered division, obeying the transformations caused by the masses of the new continents. This gave rise to another theory called Plate Tectonics. Plate tectonics is a theory originated from continental drift and ocean floor expansion.
