Section B. True-False statements. Answer ALL the questions in this section. Indicate whether each statement is true or false by WRITING ‘T’ (true) or ‘F’ (false) for each question. 1 mark for each statement, 15 marks in total. 1. Scientists study the world as it is; engineers create the world that has never been. 2. Women have more mass concentrated around the hips and above and this gives them an advantage in balance related activities. 3. Slew rate is the maximum rate at which the system can observe a changing voltage per unit time. 4. Microorganisms cannot be used as the biological element of a biosensor because they usually contaminate the analyte. 5. Bionics or biomimicry is the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology. 6. Bionic implants differ from mere prostheses by mimicking the original function very closely, or even surpassing it. 7. Much lower X-ray energies are used in mammography than any other radiographic applications. 8. Most physiological processes in humans or animals are accompanied by (or manifest themselves as) signals that reflect their nature and activities. 9. Virtual instrumentation makes it possible to combine several instruments together, customize the data collection, and perform unique data analysis that no single instrument can provide. 10. The aim of chemical engineering is to change materials from one form to another more useful (and so more valuable) form in an economic, safe and environmentally acceptable way. PLEASE TURN THE PAGE
