So you should try to answer a 3-mark question in no more than 6 lines of writing. If you are writing much more than that, you almost certainly haven’t focused your answer tightly enough. Look carefully at exactly what each question wants you to do. For example, if it asks you to ‘Explain’, then you need to say how or why something happens, not just what happens. Many students lose large numbers of marks by not reading the question carefully. Examiner’s comments Each question is followed by a brief analysis of what to watch out for when answering the question (shown by the icon ).
After a minute or so, it separates from the opsin. If this happens to all the rhodopsin in all the rod cells, you no longer have any working rhodopsin and cannot see in dim light. This explains why, if you walk from a sunny street into a dimly-lit room, you cannot see much. In the dim light, the retinal and opsin gradually combine again, forming rhodopsin, so you become able to see once more. This is called dark adaptation. The iris reflex The iris is the coloured part of the eye, surrounding a gap called the pupil.
This sends a tiny signal to a computer, which builds up an image by mapping the strengths of the signals from different parts of the brain. Haemoglobin and oxyhaemoglobin produce different signals, so the scanner is able to map where there is most oxyhaemoglobin, which indicates where neurones are most active and therefore where most blood is flowing to. By comparing the images obtained when a person’s brain is doing different things (such as reading a book, thinking about food and so on) the areas of the brain involved in these tasks can be worked out.
