The relevant field is astrobiology, the most highly funded branch of science that has the least scientific evidence supporting it. It encompasses cosmology, chemistry, geology, astrophysics, and biology predominantly and is exploring and attempting to generate knowledge on every aspect of naturalistic investigation of panspermia, habitability of exoplanets, energy sources in the cosmos, potential astro-intelligence, and composition of meteors, comets, asteroids, planets, solar systems and galaxies. The scope of astrobiology must accommodate virtually all of physical reality to be truly comprehensive.
Astrobiology is not funded well enough for the scope of the task, but is driving much of the science universe exploration projects to try to answer one of the fundamental questions of human history, is there other life and how did life come into being. Panspermia, non-directed (biochemical compounds from extraterrestrial sources of any type) and directed (intentional or non-intentional alien transmitted sources) are a prime astrobiological theoretical field and the search for extraterrestrial intelligence,SETI, is also a prime focus of astrobiology,
Answer:
With oceanic water covering 71% of its surface, Earth is the only planet known to have stable bodies of liquid water on its surface, and liquid water is essential to all known life forms on Earth. ... Water is thought to exist as liquid beneath the surface of some planetary bodies, similar to groundwater on Earth.
Answer:
The sympathetic nervous system.
Explanation:
The sympathetic nervous system prepares the body to respond quickly to external stimulation or to situations that require alertness or strength, such as situations that arouse fear, anger, excitement or shame (situations of "fight or flight"). In this type of situation, the sympathetic nervous system stimulates the heart muscles to increase the heart rate and thus increases the rate with which oxygen and nutrients are sent to the blood, dilating the bronchi of the lungs (increases oxygen retention ) and causes the dilation of blood vessels that supply the heart and skeletal muscles (increasing the blood supply). The sympathetic system innervates the sweat glands and when the body is under situations of anxiety or stress stimulates them causing perspire to occur.
