WHOEVER ANSWEERS FIRST WILL GET BRAINLIEST

A student conducted a scientific investigation on the magnetic properties of iron. She used a magnet to try to pick up iron nails.

After making several observations, which question can she answer?

Which part of a magnet is strongest at attracting iron?
How fast does iron lose its magnetism?
What is the importance of studying the magnetic field of a magnet?
How does the color of iron change with exposure to air?

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.
