Questiоn 2 Penguins аre аdаpted tо survive in cоld conditions. The adaptations help them to maintain a constant body temperature of 39 °C. Penguins also crowd together in groups of many penguins. A student wants to investigate how the temperature of a penguin is affected when they crowd together in groups. She uses this apparatus. Each test tube represents a penguin. 2.1 These statements describe the method she should use. The statements are in the wrong order. Put them into the correct order by numbering the boxes. Some have been done for you (e.g., 2.1 – 8; 2.3 – 1…) STATEMENTS ORDER 2.1. record the data in a table 8 2.2 take the temperature of the two test tubes 2.3 tie 7 test tubes together 1 2.4 heat the water to 90°C 2 2.5 take the temperatures every minute 2.6 place equal volumes of water in all test tubes 2.7 put thermometers into the middle test tube and single test tube 2.8 record data for 15 minutes 2.2 The student draws a table to record her results. Redraw the table and add suitable headings to her table. (2) 2.3 Predict how the temperature change for the single test tube will differ from the temperature change for the group of test tubes. (1) 2.4 Draw a sketch graph of the results you predict the student will obtain. (4) 2.5 Explain your prediction using ideas about thermal energy transfer. (3) 2.6 Here are two adaptations that help penguins to maintain a constant body temperature. - Most of their bodies are covered with layers of fat (1 mark) - They have flat overlapping feathers (2 marks) Explain why these two features help penguins to maintain a constant body temperature. (3) TOTAL QUESTION 2: [16]
