Andy is studying the effect of sunlight on the growth of plants. he selected three identical plants with a height of 15 cm for the experiment. andy created a data table for his observations. the first plant was kept away from sunlight, the second plant received 3 hours of sunlight, and the third plant received 5 hours of sunlight. all other growing conditions of the plants were kept constant.
which step of the scientific method will most likely come next?
analyze the data
construct a hypothesis
test with an experiment
do background research

this protocol provides a detailed procedure for chromatin immunoprecipitation (chip) to study the dna-protein interactions.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
