investigate cycling of o2 and co2
experimentation - correct answer-the scientific process of conducting
controlled tests in order to support or reject a hypothesis
oxygen-carbon-dioxide cycle - correct answer-the ongoing exchange of
oxygen gas and carbon dioxide gas that results from the processes of
photosynthesis and cellular respiration
Hypothesis - correct answer-a statement that guesses the answer to a
scientific question. the guess is made based on past experiences or
information
photosynthesis - correct answer-the process by which some organisms use
light energy to convert carbon dioxide co2 and water h2o into organic matter
and oxygen gas o2
cellular respiration - correct answer-the process by which all organisms use
sugars to produce ATP energy this process also produces co2 which
photosynthetic organisms need
biochemical pathway - correct answer-series of enzyme-controlled chemical
reactions through which cells make products
chemical equation - correct answer-summaries of the materials used and
produced by a chemical reaction or biochemical pathway
evidence - correct answer-the information contained in experimental data
qualitative - correct answer-describing an observation of an object or process
that cannot be recorded in numbers
quantitative - correct answer-describing an observation of an object or process
that can be recorded in numbers
direct observations - correct answer-observations of an object or event in real
time
