Which body system has functions that are similar to power lines in a city A:Circulatory B;excretory C:Muscular D:Nervous

The answer would be

D: Nervous.

For a quick explanation, every time you want to move, or move, your brain sends a signal to the rest of your body signaling for that specific part to move.

You can think of the brain as the power source and the nerves as the power lines, since the electricity from the brain flows through them to power a movement.

Hope this helps :))

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.
