Luis is 93 years younger than Colleen. 4 years ago, Colleen’s age was 4 times Luis’s age. How old is Luis now?

22.25 years old

Step-by-step explanation:

You substract 93 with 4, which is 89.

Then you divide 89 with 4, which leads to the answer.

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.
