If a cell has a relatively high energy need, you would expect it to have mitochondria than a cell with a lower energy need.

creative diagnostics provides a protocol for total protein extraction based on ripa which is widely used.

allowed for the prediction of the properties of missing elements.

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.
