Water droplets tend to have a neutral charge. How might they still be affected by the charges of other objects? Record your evidence.

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.

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.
