Each structure or activity lies in a specific relationsip to all other structures and activities

Organized chemical steps break down and build up molecules, making energy available or building needed parts/(gr. metabole, to change) the series of chemical reactions by wich cells aquire and use energy and that contributes to repair, growth, and other survival process

Using their own power, organisms move themselves or their body parts / the self propelled movement of an individual or its parts

Organisms perceive the environment and react to it / the dendancy of a living thing to sense and react to its surroundings

Organisms give rise to others of the same type / the method by wich individuals give rise to other individuals of the same type

Ordered sequence of progressive changes result in an individual acquiring increased complexity / the process by which an offspring increases in size and complixity from a zygote to an adult

Organisms have units of inheritance called genes that are passed from parent to offspring and control physical, chemical and behavioral traits / the transmission of genetic characters from parents to offspring

Populations of organisms change over time, acquiring new ways to survive, to obtain and use energy and to reproduce / changes in gene frequencies in a population over time

Specific structures, behaviors and abilities suit life-forms to their environment

An individual, independent living entity

A group of body parts that carries out a particular function in an organism

A structure consisting of two or more tissues that performs specialized functions within an organism

A group of similar cells that carries out a particular function in an organism / a group of cells of the same type performing the same function within the body

The simplest entity that has all the properties of life / the basic unit of life; cells are bounded by a lipid-containing membrane and are generally capable of independent reproduction

A structure within a cell that performs a specific function / a complex cytoplasmic structure with a characteristic shape that performs one or more specialized functions

A cluster of atoms held together by chemical bonds

molecules derived from living systems; the four major types are carbohydrates, lipids, proteins and nucleic acids

a type of reproduction in which new individuals arise directly from one parent

a type of reproduction in which new individuals arise from the mating of two parents

(Gr. genos, birth or race) the biological unit of inheritance that transmits hereditary information from parents to offspring and controls the appearance of a physical, behavioral, or biochemical trait; a gene is specific discrete portion of the DNA molecule in a chromosome that encodes an rRNA molecule

a taxonomic group of organisms whose members have very similar structural traits and who can interbreed with each other in nature

(pl. genera) a taxonomic group of very similar species of common descent

a taxonomic group comprising members of similar genera

a precise arrangement of structural units and activities; also in taxonomy, a taxonomic group comprising members of similar families

A taxonomic group comprising members of similar orders

(pl. phyla) a major taxonomic group just below the kingdom level, comprising members of similar classes all with the same general body plan; equivalent to the division in plants

a taxonomic group of similar classes belonging to the same phylum, which is often called a division in the gingdoms of plans or fungi

A taxonomic group composed of members of similar phyla, i.e., Animal, Plantae, Fungi, and Prostista

A taxonomic group composed of members of similar kingdoms

(L. adaptere, to fit) a particular form of behavior structure, or physiological process that makes an organisim better able to survivie and reproduce in a particular environment

t

the increased survival and reproduction of individuals better adapted to the environment

The scientific study of how organisms interact with their environment and with each other and of the mechanisms that explain the distribution and abundance of orgainisms

a group of individuals of the same species living in a particular area

Two or more populations of different interacting species occupying the same area

a community of organisms interacting with a particular environment

(Gr. bios, live + sphaira, sphere) that part of the planet that supports life; includes the atmosphere, water, and the outer few meters of the Earth's crust

a series of steps for understanding the natural world based on experimental testing of a hypothesis, a possible mechanism for how the world functions

• 1. identify a problem
• 2. propose a hypothesis
• 3. make a prediction
• 4. test the prediction
• 5. draw a conclusion

a possible answer to a question about how the world works that can be tested by means of scientific experimentation

in the scientific method an experimental result expected if a particular hypothesis is correct

a check of a scientific experiment based on keeping all factors the same except for the one in question

during the aplication of the scientific method, the phase involving the carefully planned and measured test of the hypothesis

a general hypothesis that is repeatedly tested but never disproved
