The exam paper assesses concepts in combined science, focusing on energy resources, reaction profiles, genetics, circuits, and biological cycles. It explores energy transfer in power stations, exothermic reactions, Punnett squares, and menstrual hormone dynamics. Practical tasks include circuit calculations, food web analysis, and interpreting graphical data. Keywords: “energy efficiency,“ “inheritance,“ “reaction profiles,“ “genetic terms,“ “transformer efficiency,“ “biomass transfer,“ and “respiration processes.“ Data interpretation and theoretical application are emphasized throughout.
