  1. O M G I know this! DefinitionsO Click for each heading then for the answer

  2. OVARY • Makes egg • In human and plants

  3. Ovulation • Egg is released from ovary • Day 14 of menstrual cycle

  4. V Ohms Law C x R • At constant temperature • Voltage (v) = Current (I ) x Resistance(R) Volts =amps x ohms WATCH out for the I ……”official” shorthand for current If asked for resistance R= V C

  5. Ohm • Unit of resistance (Ω)

  6. Omnivore • Animal that eats BOTH plants and animals • E.g. humans

  7. Organ • Group of tissues that work together • E.g. heart made of muscle, blood vessels and nerves.

  8. Oxygen (O2) • Needed for • respiration • Made in • photosynthesis • Carried by • red blood cells (haemoglobin) • Enters blood at • alveoli • Leaves blood at • all capillaries • Highest concentration in pulmonary vein • Made in lab using hydrogen peroxide and manganese dioxide • Double covalent bond (2 pairs of electrons shared)

  9. Omnivore • Organ • Oxygen • Do I know it?? • Ovary • Ovulation • Ohms Law • Ohm
