Biology
Not living
Abiotic
The basic unit of structure and function of all living things.
Cell
A muscular organ that pumps blood.
To change over a long period of time. For example, a species may evolve to better adapt to conditions in the environment.
Evolve
The setup in an experiment in which no change is made to which the other results are compared.
Control
A variation in an inherited trait that makes the organism better able to survive in a changing environment.
Adaptation
The process by which a parent cell divides into two or more daughter cells.
Cell Division
The enzyme controlled process in which energy is released from food and converted into a form that the cell can use.
Cellular respiration
The study of DNA and how the hereditary information is transmitted from one generation to the next.
Genetics
An instrument used by biologists to magnify the images of small objects, especially cells.
The Study of living things.
Biology
A structure found in the cell that performs a specific function.
Organelle
The nucleic acid that stores the hereditary information or genetic material.
DNA
A section of DNA on a chromosome that codes for a particular trait.
Gene
A systematic set of rules for doing science. Steps include stating a problem collecting facts through observation and experiment, and the making and testing of ideas that need to be proven right or wrong.
Scientific Method
An individual living thing.
Organism
The diffusion of water through a membrane.
Osmosis.
Refers to the heart and blood-transport system.
Cardivascular
Darwin's evolutionary theory that states that there are variations in organisms that will some organisms better fitted for survival than others.
Natural Selection.
Something that changes during an experiment.
A condition in which the number of organisms is too large for the resources of the area to support.
Overpopulation
An oval shaped organelle which is the site of cellular respiration. Energy is released from the mitochondria in the form of ATP for the cell to use.
Mitochondia
The interaction of living things and their nonliving environment.
Ecosystem
Coming from ancestors.
Inherited
A hypothesis that has been tested many times to verify its accuracy.
Theory.
