There’s always “importance of” in the title. Water was done in specimen paper so I don’t think it would come up again so soon. Anything that encompasses a lot of topics is likely e.g. homeostasis, energy transfer, control, any type of biological molecule e.g. proteins atp lipids, exchange, variation, DNA technology, gene expression, responding to stimuli, active transport, cells

i think the essay may be on the importance of gradients ( e.g. pressure gradients, water potential gradients etc.)
