How many solutions can an equation have?

It depends entirely on an equation, certain equations are meant to confuse you with numerous answers so taht you have to narrow it down, some only have one or a few. It really depends on the type of problem

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics

helicase, i think thats it
