Training improves the performance of marathon runners. Explain how the information in the table supports this statement. {Ans: 1. idea that lower resting heart rate means more potential to reach maximum heart rate ; 2. idea that higher {stroke volume / cardiac output} means more {blood / oxygen / glucose} delivered ; 3. aerobic respiration / less anaerobic respiration / less lactate produced / eq ;}Nature vs nurture {Ans: 1. idea that nature means {genetic / inherited / eq} origin ; 3. idea that nurture means {environmental / lifestyle / behaviour / eq} origin ;}Compare plant hormones to animal hormones {Ans: 1. both chemical / eq ; 2. both transported away from production site / eq ; 3. comparison of mechanism of transport described e.g. diffusion in plants, blood system in animals ; 4. speed of action compared e.g. slower in plants, some animal hormones are faster ; 5. duration of effect compared e.g. some animal hormones have a shorter term effect ; 6. idea that this plant response involves {growth / cell elongation} only e.g. animal hormones do not just affect growth ; 7. comparison of stimuli ;}Describe how a sheep could be genetically modified to
