Please help (Topic):cellular respiration and photosynthesis

The diagram below shows part of the human body
with some organs that help to carry out the removal
of wastes.
.
The energy necessary to perform this function comes
directly from the
(1) exchange of H20 and 02 during respiration
(2) blood flowing through the organs
(3) ATP molecules produced during cellular
respiration
(4) water that is eliminated by the organs

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.

not: both offer magnification to the atomic level.
