Suggest the advantages of the change in blood flow in blood vessels during exercise. [3 marks] - answer--more blood flow to muscles during exercise -supplying more glucose and oxygen/ removing carbon dioxide/ lactic acid/ heat -for high rate of respiration/ to meet increased demand for energy Explain how microorganisms contributed to the increase in temperature during processing of organic waste. [2 marks] - answer-respiration produces heat explain the advantage of showing the data using...
