Organic vs. Inorganic
organic- referring to or derived from living organisms CONTAINS CARBON
inorganic- containing no carbon
Natural vs. Synthetic
Natural-existing in or caused by nature. Not made or caused by human kind
Synthetic- made by chemical synthesis. esp to imitate a natural product.
Kinetic vs. Potential Energy
Kenetic-of, relating to, or resulting from motion.
Potential- the energy possessed by a body by a virtue of its position relative to others, stresses within itself, electric charge and other factors.
the spontaneous disintegration of a radioactive substance along with the emission of ionizing radiation.
the time taken for the radioactivity of a specified isotope to fall to half its original value.
Law of Conservation of Matter
a fundamental principal of classical physics that matter cannot be created or destroyed in an isolated system.
1st Law of thermodynamics
energy is neither created or destroyed, it changes from one form to another
2nd Law of thermodynamics
The energy available for a chemical reaction is less than that at the beginning of the reaction.
lack of order or gradual decline into disorder
an individual animal, plant, or single-celled life form. Can act or function independently
A group of living organisms that can breed and produce fertile offspring.
a group of organisms of the same species population a given area.
a group of organisms living together in one place and interacting with each-other.
all the people living in a particular area or place.
a biological community of interacting organisms and their physical environment.
An organism that that makes its own food
an organism that does not make its own food
organisms that break down wastes and dead organisms and return raw materials to the environment
Photosynthesis (reactants and products)
process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbs such as sugars and starches.
Cellular Respiration (reactants and products)
glucose+oxygen -> carbon dioxide + water + energy
Aerobic vs. Anaerobic
aerobic- with oxygen
anaerobic- without oxygen
inherited characteristic that increases an organisms chance of survival
any event that changes genetic structure
-an organism that has characteristics resulting from chromosomal alteration
a segment of DNA that is involved in producing a polypeptide chain
a distinguishing quality or characteristic
a threadlike body in the cell nucleus that carries the gene in a linear order
combined genetic information of all the members of a particular population
process by which individuals that are better suited to their environment survive and reproduce most successfully
also called survival of the fittest
the diversity of plant and animal life in a particular habitat (or in the world as a whole)
the death of a species.
movement of Earth's curst → plates float on a lower mantle layer that is hot
the breaking down of rocks, soils and minerals as well as artificial materials through contact with the Earth's atmosphere, biota and waters
a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years
Rock vs. Minerals
.A mineral is a naturally occurring solid chemical substance formed through biogeochemical processes, having characteristic chemical composition, highly ordered atomic structure, and specific physical properties. By comparison, a rock is an aggregate of minerals and/or mineraloids and does not have a specific chemical composition
Climate vs. Weather
Climate encompasses the statistics of temperature, humidity, atmospheric pressure, wind, rainfall, atmospheric particle count and other meteorological elemental measurements in a given region over long periods. Climate can be contrasted to weather, which is the present condition of these elements and their variations over shorter periods.
generic term for the mono-nitrogen oxides NO and NO2 (nitric oxide and nitrogen dioxide)
polyatomic ion phosphate
