Scientific Theories and Principles
100

One of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.

Allele

100

The basic unit of life in all living organisms, containing the genetic material and organelles in a membrane-bound structure.

Cell

100

A biological community of interacting organisms and their physical environment

Ecosystem

100

The basic structural, functional, and biological unit of all known living organisms.

Cell

100

A concept based on scientific laws and axioms where general agreement is present.

Principle (Scientific)

200

The genetic constitution of an individual organism.

Genotype

200

The series of events that take place in a cell leading to its division and replication

Cell Cycle

200

A large community of plants and animals that occupies a distinct region defined by its climate and vegetation.

Biome

200

Large complex molecules, such as proteins, nucleic acids, carbohydrates, and lipids, that are vital for biological processes

Macromolecule

200

A well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment.

Theory (Scientific)

300

The set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.

Phenotype

300

A process of cell division that results in two genetically identical daughter cells from a single parent cell

Mitosis

300

 The regions of the surface, atmosphere, and hydrosphere of the earth occupied by living organisms.

Biosphere

300

A molecule that can be bonded to other identical molecules to form a polymer.

Monomer

300

The study of the transformation of energy in living organisms.

Bioenergetics

400

A unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.

Gene

400

The division of the cytoplasm of a cell at the end of mitosis or meiosis, bringing about the separation into two daughter cells.

Cytokinesis

400

The branch of biology that deals with the relations of organisms to one another and to their physical surroundings.

Ecology

400

A substance that has a molecular structure consisting chiefly or entirely of a large number of similar units bonded together.

Polymer

400

The branch of life sciences that studies the size and age composition of populations as dynamical systems.

Population Dynamics

500

The study of heredity and the variation of inherited characteristics

Genetics

500

Unchecked cell growth

Cancer

500

An assembly of different species living in a particular area or habitat and interacting with each other.

Community (Ecological)

500

Biopolymers, essential to all known forms of life, that compose genetic information—specifically DNA and RNA.

Nucleic Acid

500

A type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
