Flashcards for Pearson Edexcel A-level Biology A, Salters-Nuffield (9BN0), split into the specification's eight context topics and then by section, with a Core practicals subdeck for the eighteen required practicals and a Maths skills subdeck for the calculations and statistical tests the specification lists. Delete or suspend any subdeck your course leaves out once the deck is yours.

Adding it gives you your own copy, with every subdeck below. Each card then comes back just before you would forget it, and every one you get right or wrong counts towards your mastery of its topic. You can delete or suspend the parts you are not studying once it is yours.

Some of its cards

  • A small molecule that can join with others to form a larger molecule, a polymer
    Monomer
  • What is the aim of the Daphnia heart rate practical?
    To investigate the effect of caffeine concentration on the heart rate of Daphnia
  • How can evolution come about through gene mutation and natural selection?
    A mutation creates a new allele; if it gives an advantage, natural selection increases its frequency in the population over generations, changing the population's characteristics
  • What is the difference between accuracy and precision in a measurement?
    Accuracy is how close a measurement is to the true value; precision is how close repeated measurements are to each other
  • The two halves of the cerebrum, responsible for higher functions such as conscious thought, memory and voluntary movement
    Cerebral hemispheres
  • What part does each of these play in producing movement at a joint: bone, tendon and ligament?
    Bones act as levers moved by muscle pull, tendons transmit that pulling force from muscle to bone, and ligaments hold the bones of the joint together
  • A neurone that carries nerve impulses from a receptor to the central nervous system
    Sensory neurone
  • What is the aim of the membrane permeability practical?
    To investigate the effect of alcohol concentration or temperature on the permeability of cell membranes, often using beetroot
  • Why might a student use a colorimeter rather than judging colour change by eye in a practical such as the beetroot or DCPIP investigations?
    A colorimeter gives an objective, numerical measurement of colour intensity, which is more precise and reliable than a subjective visual judgement
  • How is body mass index (BMI) calculated?
    BMI=mass in kg(height in m)2\mathrm{BMI} = \dfrac{\text{mass in kg}}{(\text{height in m})^2}
