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...

fMRI/EEG QUESTIONS AND ANSWERS 2023 How does fMRI work? When activity is taking place in a particular region of the brain, the neurones require oxygen. When an person lies inside an MRI machine, all of the protons in their body try to line up with the magnetic field. Protons in oxygenated blood are very organised in their spinning. However, deoxygenated haemoglobin molecules have magnetic field gradients that alter the spinning of nearby diffusion hydrogen nuclei. This less organised spinning ...
