State Ohm's law, define resistance and resistivity with their SI units, and calculate the resistance of a wire from its length and cross-sectional area.

Solve series and parallel combination problems to find equivalent resistance, current through each resistor and potential difference across each.

Apply the power relations P = VI, P = I squared R and P = V squared divided by R to compute power rating and the kWh energy consumed by household appliances over a given time.

Calculate the heat produced by a current using H = I squared R t for three appliance situations, and explain why the filament glows while the connecting wires do not.

Draw the magnetic field lines around a bar magnet and around a straight current-carrying conductor, and state the right-hand thumb rule for the direction of the field.

Explain how the field of a solenoid resembles that of a bar magnet and list three concrete ways to increase the strength of an electromagnet.

Apply Fleming's left-hand rule to find the direction of force on a current-carrying conductor in a magnetic field, and Fleming's right-hand rule to find the direction of induced current.

Describe the construction and working of an electric motor and of an a.c. generator, identifying the part that reverses current or output direction in each.

Describe a domestic circuit by listing live, neutral and earth wires, fuse, MCB and earthing, and state one safety function of each.

State the two laws of reflection and draw ray diagrams for a concave mirror and a convex mirror with the object at infinity, beyond C, at C, between C and F, at F and between F and P.

Apply the mirror formula and the magnification relation with the sign convention to find image position, size and nature for four given object distances.

State Snell's law, define refractive index between two media, and calculate the speed of light in a medium from its refractive index.

Apply the lens formula and lens power P = 100 divided by f in centimetres to solve four numericals, and list the sign conventions for a convex and a concave lens.

Explain accommodation, the near point and far point of a normal eye, and describe myopia and hypermetropia with the type and power of lens used to correct each.

Compare nutrition, respiration, transportation and excretion by writing one table per process giving the site, the input, the output and one organism-specific variation (for example, stomata in plants versus alveoli in humans).

Trace the path of blood through the human heart and contrast arteries, veins and capillaries on wall thickness, valves and direction of flow.

Explain reflex action with a labelled reflex-arc diagram, and label cerebrum, cerebellum and medulla on a brain outline with one function of each.

Name auxin, gibberellin, cytokinin and abscisic acid with one effect each, and match each major human endocrine gland to its hormone and one deficiency disorder.

Distinguish fission, budding, fragmentation, regeneration and vegetative propagation, naming one organism or plant for each mode.

Describe pollination and fertilisation in a flowering plant, and label the human male and female reproductive systems with the function of each labelled part.

Solve three monohybrid and two dihybrid crosses using Punnett squares, stating the F2 phenotypic ratio and the genotype of each parent used.

Explain sex determination in humans from the X and Y chromosomes, and distinguish acquired traits from inherited traits with one example each.

Give three lines of evidence for evolution (homologous organs, analogous organs, fossils) and define speciation, naming one factor that can drive it.

Classify biotic and abiotic components of an ecosystem, construct three food chains from a named habitat, and apply the ten per cent law to calculate energy available at successive trophic levels.

Distinguish biodegradable from non-biodegradable waste and explain biomagnification of pesticides along a food chain.

Explain ozone depletion, the greenhouse effect and acid rain by naming the pollutant responsible and one measure that reduces each.

Describe three concrete management measures for forests, three for water and three for fossil fuels, using the terms sustainable development, reuse and recycle correctly.
