  8
• What is Lithium+chlorine ➡️


  Lithium chloride
• Where does respiration take place


  The mitochondria
• What is the difference between osmosis and diffusion


  Osmosis is in liquid, diffusion is not
• What is the difference between eukaryotes and prokaryotes?


  Eukaryote has membrane bound organelles. Prokaryotes do not
• Name 5 membrane bound organelles


  Nucleus, permanent vacuole, cytoplasm, chloroplast, mitochondria
• What is a flagellum?


  A tail for a prokaryote cell
• Name an adaptation of the red blood cell

  Has a dip to carry oxygen
• Name 5 non membrane bound organelles


  Flagellum, pilli, cilia, plasmids, slime capsule
• Re

  
• What is charge flow measured in

  Coulombs
• What is the name of the area in which substrates enter the enzyme like a puzzle?


  Active site
• What is metabolism


  The sum of all reactions in a cell or body
• What does the pancreas produce?


  Amylase
• What does bile neutralise?


  Stomach/hydrochloric acid
• Charge flow(q)=current(I) x time taken(t)
• What is an ion

  A charged atom, that becomes charged when it loses or gains an electron
• What is an electron's charge

  Negative
• Who discovered the plum pudding


  Dalton
• Diffusion is where particles move from a high to low concentration
• Osmosis is diffusion in water (high to low)
• What is the name of a price of DNA that codes for characteristics


  Allele
• What is the difference between environmental and inherited variation?

  Environmental - how the environment and your surroundings affect you

  Inherited - characteristics you inherit from your family
• Name an example of environmental variation


  Dyed hair, tan
• Name an example of inherited variation


  Skin colour, eye colour, blood type
• What does the small intestine do?

  Absorbs nutrients into the bloodstream
• What is genetic modification?


  Altering an organisms genes to produce a desired chatacteristic.
• what is the definition of a catalyst

  something that speeds up the reactions of things like enzymes.
• current x time= charge
• diodes allow electrons to flow in only 1 direction

  
• the potential difference across a component is measured using a volt meter
• the current through a circuit is measured by an ammeter
• A diode allows electricity to pass in one direction only
• The current through a component is measured using an ammeter
• In parallel circuits there are multiple paths for the electric current to follow, this means that even if some parts of the circuit break down other components still work
• An LDR (light dependant resistor) changes a circuits resistance depending on the light. If it was dark, it restists a lot

  
• S²+

  16 protons 18 electrons
