Evaluate each expression if m equals 3 and n equals 7, 3mn is?

3 x 3 x 7 = 63

Step-by-step explanation: I am not sure if this is what you are asking but when a number and a variable and next to each other without any spaces it means that you should multiply them, so, 3 x m is just 3 x 3. Expanding on this, if 3 x 3 x n is equal to 3 x 3 x 7 then you can just multiply 3, 3, and 7 for a total of 63.

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.

where did you get them? if you picked from the grass, is is probably poisonous.
