which of these is an advantage of multicellular organisms?

a. they can form complex organ systems
b. all of the cells are the same
c. they can reproduce quickly
d. one cell performs all of the necessary functions

for question 1 i think it is d.
and for question 2 i think it is a

it is either c or d and i know for sure it is not a or b

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.
