As a scientist working for an anti-bioterrorism task force, you are asked to evaluate some biological samples for the presence of yersinia pestis, the organism that causes the plague. after confirming that the samples do contain y. pestis, you instruct your team to begin sequencing the strain. since the genome sequence of y. pestis is already known, why would sequencing this strain be useful

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.
