An internet reaction time test asks subjects to click their mouse button as soon as a lightflashes on the screen. The light is programmed to go on at a random time from 2 to 5 seconds after the subject clicks “start.” Below is a density curve for the time at which the
light goes on.
(b) Find the proportion of times that the light goes on between 2.5 and 4 seconds after the
subject clicks "start."

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
