Need a matching side-angle pair to start. Angle sum 180 deg finds the third angle when two are known. SSA can give 0, 1, or 2 triangles (ambiguous case).
Two genes, independent assortment (different chromosomes in the school model). RrYy x RrYy (round yellow peas school) gives 9 : 3 : 3 : 1 phenotypes if both…

Synaptic Transmission: The movement of impulse across the synapse is called synaptic transmission. It takes place in the formation of a message which is…
Disease control combines clean water, sanitation, hygiene, ventilation, vaccination, vector control, surveillance, testing and appropriate treatment.
The term synapse comes from the Greek words 'syn', which means 'together' and 'haptein' meaning 'to clasp'. A synapse is the junction…
Viscosity is a fluid's resistance to flow. Viscous drag opposes relative motion through a fluid, and for a small sphere in laminar flow Stokes' law gives F_d =…

Polar molecules, dipole. b.p. higher than the alkane of similar size (extra force). Insoluble in water like many organics. No solvent-abuse guide.…
School names for ammonia and nitric acid centre on two industrial routes: the Haber process makes NH₃ from N₂ and H₂; the Ostwald process oxidises ammonia…
Ionic bonds are formed between two atoms when one atom loses electrons to form a cation and the other atom gains those electrons to form an anion.…
Air pollution occurs when air contains harmful particles and gases. Such air is said to be polluted. Simple explanation: Air pollution is when…

Osmoconformers: Those animals that change the osmotic concentrations of the body fluids according to that of surrounding medium are called osmo-conformers.…
Cracking: big alkanes -> smaller alkanes + alkenes (more petrol, more ethene). Thermal or catalytic named. Reforming: straight chains to branched or rings…
Diffraction occurs when waves bend around obstacles or spread after passing through an opening. It is most noticeable when the obstacle or aperture size is…
A complex number is z = a + bi with real a (real part) and real b (imaginary part). The set is C. Every real is complex: a = a + 0i, so R is inside C. Pure…
Three titres within 0.1 cm^3 are precise. If you used the wrong indicator, they can still be invalid. An outlier: check the burette, do not hide it. Accuracy…
Alcohols burn: CO2 + H2O if complete (ethanol fuel slogan, not a still design). Dehydration: hot conc H2SO4 or Al2O3 named, lose water, make an alkene (ethanol…
2x-1x2+3 is rational. sqrt(x+1) is not. Domain: exclude zeros of the bottom. Reducing comes after factoring, next pages.
