- - - - deoxygenated blood enters the heart via vena cava into the right atrium
      - Blood then travels through the tricuspid valve into the right ventricle
      - Blood then travels through the semilunar valve into the pulmonary artery
      - Blood returns from lungs to the left atrium vai the pulomary veins
      - Blood travels from the left atrium thrpught he bicuspid valve into the left ventricle
      - Blood travels from left ventricle to the rest of the body via arota
    - - superior vena cava
      - right atrium
      - ventricle valve
      - Interior vena cava
      - right ventricle
      - pulmonary valve
      - pulmonary artery
      - pulmonary vein
      - aovil valve
      - left ventricle
      - miral valve
      - left atrium
      - pulmonary vein
      - aorta
- - - - Gametes are reproductive cell for sex cells
  - - - The bases of DNA are A, T, C and G which are all nucleotides
      - the paring of bases in DNA is A with T and C with G
      - DNA strands are held together by phosphodiesterase bonds
      - DNA can be extracted from fruit by smashing up the fruit in a bag after the green bit as been taken off. Then adding cold ethanol to the bag and mixing it in with the mashed up fruit. Then after that you filter the mashed up bits out and you take a sample of it and should see white liquid which is the DNA
      - in eukaryotic cells the DNA is found in the nucleus
      - The structure of a DNA is a double helix shape
