VERSION BY EXPERTS \NEW AND REVISED
Theory - ANSWER- A hypothesis that has been tested with a significant
amount of data, backed by strong evidence
Law - ANSWER- A descriptive statement or equation that reliably
predicts events under certain conditions
Hypothesis - ANSWER- A testable prediction, often implied by a theory
Control - ANSWER- In an experiment, the standard that is used for
comparison
Experimental group - ANSWER- In an experiment, the group that is
exposed to the treatment, that is, to one version of the independent
variable.
Independent variable - ANSWER- The experimental factor that is
manipulated; the variable whose effect is being measured. Plotted on the
x axis
,2|Page
Dependent variable - ANSWER- The outcome factor; the variable that
may change in response to manipulations of the independent variable.
Plotted on the y axis
Autotrophs - ANSWER- Organisms that are able to make their own food
Heterotrophs - ANSWER- An organism that obtains organic food
molecules by eating other organisms or their by-products.
Diffusion - ANSWER- Movement of molecules from an area of higher
concentration to an area of lower concentration; requires no energy
Osmosis - ANSWER- Diffusion of water through a selectively
permeable membrane; moves from higher to lower water concentration
Active transport - ANSWER- Energy-requiring process that moves
material across a cell membrane against a concentration difference
Botany - ANSWER- The scientific study of plants
Biology - ANSWER- The scientific study of life
Chemistry - ANSWER- The study of the properties of matter and how
matter changes
, 3|Page
Genetics - ANSWER- The scientific study of heredity
Ecology - ANSWER- Scientific study of interactions among organisms
and between organisms and their environment
Evolutionary Biology - ANSWER- The study of organisms and their
changes
Molecular Cell Biology - ANSWER- The study of the molecules and the
structures that make up the cell, the reactions that occur within the cell,
including DNA.
Stomata - ANSWER- Small openings on the underside of a leaf through
which oxygen and carbon dioxide can move
Guard cells - ANSWER- The two cells that flank the stomatal pore and
regulate the opening and closing of the pore.
Respiration - ANSWER- Biochemical process in which an organism
gets energy by breaking bonds of ATP
Aerobic respiration - ANSWER- The process by which cells convert
glucose and oxygen into energy, carbon dioxide, and water.
Anaerobic respiration - ANSWER- Respiration in the absence of
oxygen. This produces lactic acid.
