Choose the statement below that accurately represents a significant feature of graded potentials. graded potentials activate enzymes to excite the cell. like graded potentials can sum to create a larger graded potential. like graded potentials will subtract from each other to create a smaller graded potential. graded potentials randomly occur all the time but are of no significance.

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation 2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!
