A=the most available energy and B=the least amount of energy available
and B have the same amount of energy
=the least amount of energy and B= the most available energy
A and B have infinite amount of energy

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.

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.

cuz some people don't have enough food. that's why we need more ppl to donate food to the hungry.
