Here are the answers to your questions: 3.1.1 a) The specialised cells in the nervous system that are affected by MS are neurons. b) The part of the cells named in QUESTION 3.1.1(a) that are damaged is the myelin sheath. 3.1.2 The relationship between age and the occurrence of MS in men up to the age of 69 shows a general increase. The number of people with MS in men steadily rises from 0 in the 14-19 age group to 400 in the 60-69 age group. 3.1.3 To draw a histogram representing the results in women aged 40 to 79, follow these steps: 1. Title: Give the histogram a clear title, e.g., "Occurrence of Multiple Sclerosis in Women Aged 40-79". 2. X-axis (Horizontal): Label this axis "Age Group (Years)". Mark the intervals for the age groups: 40-49, 50-59, 60-69, and 70-79. 3. Y-axis (Vertical): Label this axis "Number of People with MS (per 100 000 people)". Choose an appropriate scale that goes up to at least 620 (the highest value), for example, increments of 100. 4. Draw Bars: For each age group, draw a bar whose height corresponds to the number of people with MS: 40-49: 450 50-59: 620 60-69: 600 70-79: 240 The bars should be adjacent to each other, as a histogram represents continuous data. 3 done, 2 left today.
