Identify the source of knowledge deductive reasoning, inductive reasoning , or the scientific approach most prominently used in the following examples: a. After extensive observation of reactions, Lavoisier concluded that combustion is a process in which a burning substance combines with oxygen. His work wasthe death blow to the old phlogiston theory of burning.
b. Dalton, after much reflection, concluded that matter must consist ofsmall particles called
atoms. His early assumptions became the basis for the atomic theory.
c. Later scientists took Dalton’s assumptions, made deductions from them, and proceeded to gather data that confirmed these assumptions. They found support for theatomic theory.
d. Knowing that radioactive substances constantly give off particles ofenergy without apparently reducing their mass, Einstein developed the formula E=mc2 forconverting matter into energy.
e. Accepting Einstein’s theory, Fermi carried on experimentation thatresulted in splitting the atom.
f. After studying reinforcement theory, a teacher hypothesizes that using atutorial computer program will lead to superior achievement in arithmetic. She devises a studyin which the tutorial is used with two sixth-grade classes, whereas conventional materials areused with two other sixth-grade classes.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
