Red tide is a common name for algal blooms, which are large concentrations of aquatic microorganisms, such as protozoans and unicellular algae.
The upwelling of nutrients from the sea floor, often following massive storms, provides for the algae and triggers bloom events
Pediculosis capitis, also known as hair lice, is one of the most common of ectoparasitic infections. This is highly contagious, especially in schools, day care centers, or areas wherein children are in close contact with infected children.

The precambrian era makes up about 90% of the earths history, but there was little to no living organisms at the time other than microscopic ones. The first eukaryotes were found in the cambrian period after the precambrian period, not only that but at the end of the precambrian era in the Proterozoic era there was a mass extinction of about 70-80% of all living organisms
True.
The earth is made of several subsystems or spheres that interact to form a complex and continuously changing (dynamic) state that is termed as the earth system.
Even though the earth system is a closed system, it self regulates through the subsystems such as the water cycle and carbon cycle.
The earth system is characterized by numerous overlapping cycles in which matter is recycled over and over again. Cycles involve multiple spheres and systems interactions. Humans impact and are impacted by the cycles in various ways.
