So the graph below shows the radioactive decay of two materials. which of these statements is correct about material 1 and material 2? a. the half-lives of material 1 and material 2 are same. b. the half-life of material 2 is one-fourth of the half-life of material 1. c. the half-life of material 2 is 5 years more than the half-life of material 1. d. the half-life of material 1 is 5 years more than the half-life of material 2.

Iwould say the answer is c

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.

It depends on the surface of the levels. the rougher the surface, the greater is the frictional force. for rougher surfaces, you would need to exert greater force to move the object. the concept is that, you must overcome the frictional force in order to bring the object into motion. this is the reason why we add lubricants to the joints so they could easily move. this answer was on
