Chapter 1: The Study of Life Flashcards
Adaptation
Inherited characteristic of a species that develops over time in response to environmental factor, enabling the species to survive.
Biology
Science of life; examines how living things interact, how systems function, and how they function at a molecular level.
Biotic factor
Any living factor in an organism’s environment
Development
Changes an organism undergoes in its lifetime before reaching its adult form.
Energy
Ability to do work; energy cannot be created or destroyed, only transformed.
Evolution
Hereditary changes in groups of living organisms over time.
Growth
Process that results in mass being added to an organism; may include formation of new cells and new structures.
Homeostasis
Regulation for organism’s internal environment to maintain conditions needed for life.
Organism
Anything that has or once had all the characteristics of life.
Organization
Orderly structure shown by living things
Reproduction
Production of offspring
Response
Organism’s reaction to a stimulus
Species
Of organisms that can be interbreed and produce fertile offspring
Stimulus
Any change in an organism’s internal or external environment that causes the organism to react
Analyze
Interpret
Accuracy
How close a group of measurements are to the real or accepted value
Bias
Particular preference of point of view that is personal, rather than scientific
Bioethics
Study of controversial issues that develop as a result of a discovery made in biology
Conclusion
A summary of the results in an investigation and what they mean
Constant
A factor that remains fixed during an experiment with the independent and dependent variables change
Control group
In a controlled environment, the group not receiving the factor being tested
Data
Quantitative or qualitative information gained from scientific investigation
Dependent variable
Factor being measured in a controlled environment; it’s value changes because of changes to the independent variable
Error
The difference between the measured value and the real value
