the ability of a living thing to keep conditions inside its body constant
large molecule formed when many smaller molecules bond together
The movement of materials (nutrients) in a local ecosystem
a living thing that has (or can develop) the ability to act or function independently
having a pair of equal and opposite charges
not ionic
term referring to matter having an excess of electrons (a negative charge) or a deficiency of electrons (a positive charge)
Water Fearing
Water Loving
the dissolved substance in a solution
a liquid substance capable of dissolving other substances
a chemical bond that involves sharing a pair of electrons between atoms in a molecule
(physics and chemistry) the simplest structural unit of an element or compound
a chemical bond consisting of a hydrogen atom between two electronegative atoms (e.g., oxygen or nitrogen) with one side be a covalent bond and the other being an ionic bond
any very large complex molecule
tiny structures that carry out functions necessary for the cell to stay alive
groups of individuals that belong to the same species and live in the same area
(ecology) a group of interdependent organisms inhabiting the same region and interacting with each other
a system formed by the interaction of a community of organisms with their physical environment
a major biotic community characterized by the dominant forms of plant life and the prevailing climate
a simple compound whose molecules can join together to form polymers
reproduction in which the genes from two parents join to make an offspring
a type of reproduction involving only one parent that produces genetically identical offspring by budding or by the division of a single cell or the entire organism into two or more parts
The passing of traits from parents to offspring
set of chemical reactions through which an organism builds up or breaks down materials as it carries out its life processes
an attraction between molecules of different substances
attraction between molecules of the same substance
a phenomenon associated with surface tension and resulting in the elevation or depression of liquids in capillaries
a phenomenon at the surface of a liquid caused by intermolecular forces
the environment as it relates to living organisms
living
non-living
(ecology) a community of organisms where there are several interrelated food chains
The hierarchical levels of the food chain through which energy flows from primary producers to primary consumers, secondary consumers and so on.
organism capable of synthesizing its own food from simple organic substances
a series of steps in which organisms transfer energy by eating and being eaten
an organism that depends on complex organic substances for nutrition
an organism that makes its own food
an organism that obtains energy by feeding on other organisms
any animal that feeds chiefly on grass and other plants
any animal that feeds on flesh
an animal that feeds on both animal and vegetable substances
organism that breaks down and obtains energy from dead organic matter
only 10% of the total energy produced at each trophic level is available to the next level. The amount of energy passed up to the levels of the food pyramid reduces as you go up.
warming that results when solar radiation is trapped by the atmosphere
a gas that contributes to the greenhouse effect by absorbing infrared radiation
a change in the world's climate
process by which plants use the sun's energy to convert water and carbon dioxide into sugars
the metabolic processes whereby certain organisms obtain energy from organic moelcules
the law that states that energy cannot be created nor destroyed
whenever energy is converted from one form to another form some energy is lost as heat
the process of becoming a vapor
the emission of water vapor from the leaves of plants
the process of changing from a gaseous to a liquid or solid state
the falling to earth of any form of water (rain or snow or hail or sleet or mist)
water that flows over the ground surface rather than soaking into the ground
water that leaks out and slowly moves deeper underground
plant roots absorb the water
the assimilation of atmospheric nitrogen by soil bacteria and its release for plant use on the death of the bacteria
without oxygen
process that requires oxygen
a fundamental principle of classical physics that matter cannot be created or destroyed in an isolated system
A way of measuring how much of an impact a person or community has on the earth. Someone who uses more natural resources will have a bigger footprint than someone who uses less.
H2o
chemicals produced by the body break foods into their smaller chemical building blocks
Part of digestion that uses movement and muscles to break down food
the process of wave-like muscle contractions of the alimentary tract that moves food along
a semiliquid mass of partially digested food that passes from the stomach through the pyloric sphincter into the duodenum
protein substances that speed up chemical reactions.
(chemistry) a substance that initiates or accelerates a chemical reaction without itself being affected
the part of an enzyme or antibody where the chemical reaction occurs
the substance acted upon by an enzyme or ferment
the elements or compounds produced by a chemical reaction
unit of heat defined as the quantity of heat required to raise the temperature of 1 gram of water by 1 degree centigrade at atmospheric pressure
a unit of the energy supplied by food
the opening through which food is taken in and vocalizations emerge
a clear liquid secreted into the mouth by the salivary glands and mucous glands of the mouth
any of a group of proteins found in saliva and pancreatic juice and parts of plants
an enlarged and muscular sack like organ of the alimentary canal
the passage between the pharynx and the stomach
digestive organ in which most chemical digestion takes place
Large organ just above the stomach that produces bile
a digestive juice secreted by the liver and stored in the gallbladder
stores bile until needed for digestion
gland that secretes pancreatic juice into the duodenum, where it mixes with bile to digest food
Small fingerlike projections on the walls of the small intestines that increase surface area
the last section of the digestive system, where water is absorbed from food and the remaining material is eliminated from the body
the cavity in which the large intestine begins and into which the ileum opens
the part of the large intestine between the cecum and the rectum
A short tube at the end of the large intestine where waste material is compressed into a solid form before being eliminated
opening of the rectum to the outside of the body
a vestigial process that extends from the lower end of the cecum and that resembles a small pouch
Model of enzyme activity that explains how a particular enzyme will only fit with one particular type of substrate.
the energy that an atomic system must acquire before a process (such as an emission or reaction) can occur
the extent of a 2-dimensional surface enclosed within a boundary
