Step-by-step explanation:

To remember the order of operations, it is best to use the PEMDAS acronym; Parenthesis, Exponents, Multiplications, Division, Addition, Subtraction.

A good way to remember this is with the phrase: Please Excuse My Dear Aunt Sally.

So, applying PEMDAS to your question:

3 - 9/(-1) * 3

We first need to divide 9 by -1

3 + 9 * 3

Then, we multiply 9 by 3

3 + 27

Finally, we add 3 and 27

Hope this helps.

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.
