What was John Dalton's atomic theory? - Answer all matter is made of atoms that couldnt be broken down What did JJ Thomson discover? - Answer discovered electrons that could be removed from atoms and he suggested that atoms were spheres of positive charge with tiny negative electrons inside What did Rutherford discover? - Answer by firing alpha particles at thin gold foil, he found that most particles passed through and a few deflected back. This means that that most of the mas...

What is a mutation? A change in the DNA sequence What are the 6 types of mutation? (Things that happen with bases) Substitution Deletion Addition Duplication Inversion Translocation What is a hereditary mutation? When a gameate containing a mutation for a type of cancer or genetic disorder is fertilised then it will be present in new foetus What happens during frameshift mutations? Additions, duplications or deletions within a gene change amino acid sequence causing a shift in the b...

Transverse waves The vibrations are at right angles to the direction of travel. Longitudinal waves The vibrations are along the same direction as the direction of travel. Examples of transverse waves Light and other types of electromagnetic radiation, as well as water waves and S waves (a type of seismic wave). Examples of longitudinal waves Sound waves and waves in a stretched spring, and P waves. Equation linking time, period and frequency Period = 1/frequency Equ...
