Scientists have recently discovered two multicellular organisms with different components in their cell walls. the cell walls have two different polysaccharides, cellulose and chitin. in which two kingdoms would these two multicellular organisms be grouped?

Fungi's are multicellular organisms and contain chitian in there cell walls and plants which belong to the plantae kingdom are also multicellular but they have cellulose in the cell walls.

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.

the correct answer to this question is #5
