Why is it important to drink adequate amounts of water each day? water to regulate body temperature. water to lubricate the joints. water dissolves solutes, which allows chemical reactions to occur. all of the above?

I think the answer is all of the above.

Bis the right answer

You did not show us the image of the burger, but i shall try to answer as best i can.  when purchasing food, always consider the ingredients as well as the person who prepared it. consider if they were hygienic people or not, in case the burger was infected with bacteria. no mortal should place an infected burger into their mouth.
