Why do cells go to the trouble of making ATP when they already have glucose molecules? a
prokaryotes cannot use glucose at all, so they must make ATP
b
an ATP molecule holds more energy than a glucose molecule
c
glucose holds too much energy; ATP is easier to spend on cell work
d
because eukaryotes are complex, they must complicate all chemical reactions

The table presents the average day and night temperatures in five cities. it also reveals whether a city receives substantial rainfall (wet climate) or little rainfall (dry climate). which city’s rocks are likeliest to experience frost wedging, and why? a) city a because the consistently subzero temperature would prevent water from melting b) city b because it is a wet region and the temperature fluctuates around the freezing point c) city c because it receives plenty of rain fall and the weather is moderately cool d) city d because the hot and dry weather would cause rocks to absorb water

The scales shown in the introduction measure mass, or the amount of matter in a particular object. the scientific law of conservation of mass states that matter cannot be created or destroyed during a chemical reaction, but it can change from one form to another. did the simulation support this scientific law? explain why or why not.
