gregor mendel used pea plants that were heterozygous for each of two traits—seed color and seed shape_to generate a
dihybrid cross. the phenotypic ratio of the resulting offspring was nine with round and yellow seeds, three with round and
green seeds, three with wrinkled and yellow seeds, and one with wrinkled and green seeds. from these results, what could
mendel conclude?

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.
