Well calculating magnification and image and object size from the formula magnification=image size/object size

measuring size of microorganisms, organelles, cells form a stage micrometer and graticule is important

questions on calculating the number of chromosomes which basically involves knowing if the cell is haploid or diploid or has undergone mitosis or meiosis are very common

sometimes they ask to calculate vital capacities from a graph or otherwise

and calculations about the cardiac cycle, like the timings of atrial and ventricular systole and diastole from a graph, are very rare but do come
thats about all i can remember.
