Biology Flashcards
Factor in a controlled experiment that is deliberately changed; also called manipulative variable.
indepandent variable
Variable that is observed and that changes in response to the independent variable; also called the responding variable
Depandent variable
Evidence; information gathered from observation
data
A logical interpretation based on prior knowledge and experience
inference
Well-tested explanation that unifies a broad range of observations and hypotheses, enabling scientists to make accurate predictions about new situations
theory
Define bias
Particular preference or point of view that is personal rather than scientific
Group in an experiment that is exposed to the same conditions as the experimental group except for one independent variable
control group
The act of noticing and describing events or processes in a careful orderly way.
observation
What is the definition of science?
The use of evidence to construct testable explanations
What does science propose explanations based on?
Based on evidence and understanding
What is a hypothesis?
Testable explanation that can be tested
What happens after a hypothesis is formed?
A controlled experiment
descriptions, characteristics that cannot be measured
qualitive data
Define quantitative data
numbers, characteristics, that can be measured
What happens if an experiment proves a hypothesis?
experiments is repeated be gather more supporting data
What happens if an experiment disproves a hypothesis?
hypothesis is changed and a new experiment is created
When is a theory formed?
After multiple experiments and support from other research
What is the definition of biology?
The study of life
How many characteristics of life are there?
8
What does M stand for in the characteristics of life? give an example.
M: Metabolism, combination of chemicals
What does R stand for in the characteristics of life? GIve an example (there’s 2)
R: Reproduction, new organisms or offspring; R: Response to stimulus, reacting to a signal.
What does C stand for in the Characteristics of life? Give an example.
C: Cell, living things are made up of one or more
What does H stand for in the characteristics of life? Give an example.
H: Homeostasis, relatively consistent internal physical and chemical conditions
What does E stand for in the characteristics of life? Give an example.
E: Evolution, change over time
What does D stand for in the characteristics of life? Give an example. (there’s 2)
D: DNA, genetic code; D: Development and Growth, process of growing and maturing
WHat is the difference between maturing and getting bigger?
Maturing is when you develop, and getting bigger is when your growing
