In a particular plant, green seed color is dominant to yellow seed color if a homozygous green seed plant is crossed with yellow seed plant what percent of the offspring would be heterozygous

yes? sounds right, but you didn’t ask a question.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

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.
