18. At my son's birthday party, we had a piñata that we filled with 140 pieces of candy. If there were 42 Hershey chocolate bars, what percent of the candy was Hershey chocolate bars?
19. On a recent test, there were 15 multiple-choice questions and 25 fill-in-the-blank problems. What percent of
the problems were fill-in-the-blank problems? (Hint: How many problems were on the entire test.)

18.  30%

19.  62.5%

Step-by-step explanation:

42/140  mult by 100       30%

25 + 15 = 40

25/40   mult by  100 62.5%

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.
