Question isnt well formatted.

Jonathan has a jar filled with Nicholas dollars in quarters he has 57 coins in total and the value of those coins is $6.50 if he has 20 knuckles how many dollars in quarters does he have

Step-by-step explanation:

Number of Nickels = n

Number of Quarters = k

n + k = 57

5n + 25k = 650

If n = 20

k = 57 - n

k = 57 - 20

k = 37

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.
