Life is a quality that distinguishes matter that has biological processes, such as signaling and self-sustaining processes, from matter that does not. It is defined descriptively by the capacity for homeostasis , organisation , metabolism , growth , adaptation , response to stimuli , and reproduction .
Earth system science – Scientific study of the Earth's spheres and their natural integrated systems; Extraterrestrial life – Life that does not originate on Earth; Information metabolism – Psychological theory of interaction between biological organisms and their environment; Organism – Individual living life form
Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe. [1] [2] Modern science is typically divided into two or three major branches: [3] the natural sciences (e.g., physics, chemistry, and biology), which study the physical world; and the social sciences (e.g., economics, psychology, and sociology), which ...
Human longevity is affected by a complex number of factors, including lifestyle. Through modifiable lifestyle behaviors, including diet, exercise, and limiting sedentary behavior, you can improve ...
Extreme fire behavior, including "short and long-range spotting," continues to challenge firefighting efforts, Cal Fire said in an incident update Wednesday. The fire was listed as "0%" contained.
Geochemistry – Science that applies chemistry to analyze geological systems – study of chemistry of the Earth's crust; Geochronology – Science of determining the age of rocks, sediments and fossils – study of measuring geological time; Geography – Study of lands and inhabitants of Earth – study of surface of the earth and its ...
The emergence of life with increasing order and complexity does not contradict the second law of thermodynamics, which states that overall entropy never decreases, since a living organism creates order in some places (e.g. its living body) at the expense of an increase of entropy elsewhere (e.g. heat and waste production).
The components of long-term fire retardants are mainly salts – typically agricultural fertilizers – that "alter the way the fire burns, decreases the fire intensity, and slows the advance of ...
