A physical or chemical change in an organism’s internal or external environment

What is a stimulus?

Maintaining a stable internal environment

What is homeostasis?

Total of all the chemical reactions in an organism

What is metabolism?

Process where organisms become mature adults

What is development?

Two “E’s” required by all organisms

What are Energy and Enzymes?

Chemical compounds that provide physical structure in organisms

What are biological molecules?

High degree of order between an organism’s internal and external parts

What is organization?

Smallest unit that can perform all life’s processes

What is a cell?

Structures that carry out specialized jobs within an organ system

What is an organ?

Group of cells that have similar abilities and that allow an organ to function

What are tissues?

The process in which all organisms produce new organisms like themselves

What is reproduction?

Large molecule containing the hereditary code for an organism

What is DNA?

Hereditary information from two individuals is combined in their offspring

What is sexual reproduction?

Daily Double!!

A short segment of DNA that codes for a protein or polypeptide

What is a gene?

Single organism divides producing genetically identical cells

What is asexual reproduction?

Branch of biology that studies organisms interacting with each other & their environment

What is ecology?

Communities of organisms and their physical environment

What is an ecosystem?

The rules that govern how cells use the hereditary instructions in their DNA

What is the genetic code?

The three domains of life

What are Archaea, Bacteria, and Eukarya?

The six Kingdoms of life

What are Archaebacteria (Archaea), Eubacteria (Bacteria), Protista, Fungi, Plantae, and Animalia?

Traits that improve an individual’s ability to survive and reproduce

What are adaptations?

Organisms with favorable traits survive & reproduce to pass on their genes

What is natural selection?

Helps us understand how populations of organisms came into existence & how they’ve changed over time

What is evolution?

Rabbits with white fur and short ears in snow would be an example

What are adaptations?

Daily Double!!

Also known as “Descent with Modification”

What is Darwin’s idea of evolution?

Organized approach used in science to explain observations of the natural world

What is the scientific method?

First step in a scientific study

What is observation of the natural world?

A statement that proposes an explanation to a scientific question

What is a hypothesis?

A group in an experiment that is used for comparison

What is the control?

Numerical data collected in a scientific experiment

What is quantitative data?

Final Jeopardy

Measurement

Metric unit most likely to be used to measure the size of a cell

What are micrometers?
