Wednesday, 01 December 2021 Revision 2 LO: To revise for the end of cycle assessment. Biology Describe how contraceptive methods prevent pregnancy Chemistry How can sedimentary rock turn into metamorphic rock? Physics Describe the difference between the inner and outer core. Q1: What does the presence of tiny crystals in a piece of igneous rock tell you about it? Q2: What is Magma? Q3: Which type of rock never contains fossils? Q4: Which part of a cell is in charge of passing on information? Q5: Describe how a Vaccination can prevent disease. Q6: Where does fertilisation take place? Q7. A disc containing penicillin made a clear area 18 mm across on a bacterial plate. What is the area of the clear zone? Q8. Which is a natural occurrence that happens due to the movement of plates? Q9. How can a Metamorphic rock change into an igneous rock? Q1: What does the presence of tiny crystals in a piece of igneous rock tell you about it? Tiny crystals in igneous rock tell you that the molten rock cooled quickly. Q2: What is Magma? Molten Rock. Q3: Which type of rock never contains fossils? Igneous rock never contains fossils. Q4: Which part of a cell is in charge of passing on information? Genetic Material Q5: Describe how a Vaccination can prevent disease. Vaccine contains a dead or weakened form of the bacterium or virus. White blood cells produce antibodies which destroy toxins and prevent further infections Q6: Where does fertilisation take place? Oviduct Q7. A disc containing penicillin made a clear area 18 mm across on a bacterial plate. What is the area of the clear zone? 𝑨 = 𝝅𝒓𝟐 = 𝟑. 𝟏𝟒 𝒙 𝟗𝟐 = 𝟐𝟓𝟎 𝒎𝒎𝟐 Q8. Which is a natural occurrence that happens due to the movement of plates? Earthquakes happen when plates collide or slide past each other. This is a natural occurrence caused by movement of plates. Q9. How can a Metamorphic rock change into an igneous rock? Weathering (breaking down rock) and erosion (transporting rock material) at or near the earth’s surface breaks down rocks into small and smaller pieces. If the newly formed metamorphic rock continues to heat, it can eventually melt and become molten
