Aruler has markings as shown below. stefan uses this ruler to measure the length of a metal rod. how many decimal places should his answer include?

Based on a ruler in centimeters, with ten divisions between each centimer mark, you will have marks at every 0.1 cm.

Then, the measure of the length of a metal rod should have 1 decimal place.

That decimal place means mlimiters, given that 1 mm = 0.1 cm.

1 decimal place

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.
