For a survey, a company decided to call 7 out of every 5,000 people. how many people should be called in a town of 78,000 people

x/78000 = 7/5000 so

x= 7* (78000)/5000 = 546/5 = 109,2 and it is probably OK round that to 109 people.

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.
