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.

The percent efficiency of a machine can never be 100% (or greater), because in the real world some energy is always converted into a. heat b. work c. input force d. output force

For the below questions, consider a consumer that consumes two goods, x and z with the following utility function. u with bar on top space equals space x to the power of 1 third end exponent z to the power of 2 over 3 end exponent suppose initial values for income and the prices of goods x and z are y equals 90, p subscript x equals space 10, and p subscript z equals 15 respectively, then the price of good x falls to syntax error from line 1 column 89 to line 1 column 100. unexpected '\'.. what is the magnitude of the total effect
