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