chromoseomes arrived into a place named metaphase plate which is located in equal distance from each pole, this occurs at metaphase of mitosis. and also the centrosomes reache the opposite poles at this stage.

frogs. the lower the ph the higher the acid content. frogs have the highest tolerance in this scenario.

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.
