Nature of Science Ethical implications of research The use of animals in experiments may generate ethical issues. These are discussed in Appendix 3: Defining ethics and making ethical decisions on the accompanying website. Figure 2.64 4 after a fixed time, the syringe is adjusted to level the fluid in the two arms of the manometer, and the valume of O absorbed is read off on the syringe A respirometer to measure respiration rate graduated syringe- cips A and Bare closed -hypodermic needie -respirometer tube control tube (thermobarometer) water bath glass beads (same volume as sample in respirometer tube) 1 the respiring organisms gve off Co, and absorb O soda lime peliets- (Co, absorbent) -soda lime pellets (CO, absorbent 2 co, is absorbed by the soda lime U-tube manometer Any change in pressure or temperature during the experiment affects the respirometer tube and the themobarameter tube equally. 3 manometer fluid moves to the right due to the volume change caused by uptake of orygen 28 In the respirometer (Figure 2.64), explain how changes in temperature or pressure in the external environment are prevented from interfering with measurement of oxygen uptake by respiring organisms in the apparatus. 29 The experiment shown in Figure 2.64 was repeated with maggot fly larvae in tube B, first with the soda lime present and subsequently with water in place of soda lime. The volume change with soda lime was 30mm3h-1, but without soda lime it was 3mm3 h- 1. Analyse these results, explaining the significance of each value.
