A. Carbonic acid with limestone
Answer:
The molecules that bind cellular respiration enzymes act as signals, giving the enzyme information about the cell's energy state. ATP and ADP are examples of molecules that regulate cellular respiration enzymes. ATP, for instance, is a "stop" signal: high levels mean that the cell has enough ATP and does not need to make more through cellular respiration.
This is a case of feedback inhibition in which a product feeds back to shut down its pathways.
Cameras and video-shooters are essentially tough. They can withstand a lot, from insects to shark bites. However, in order to withstand being outside for such a long time of three years? That's a little tricky.
As we all know, the batteries can corrode if left in damp places, or if left in for too long. Therefor, this can't be damp. Nowadays, most cameras have plastic in various places, so leaving it somewhere hot could inevitably melt it. You don't want that. If your camera is left in the cold, (18°F, 10°C) then the batteries could be severely changed. If left in a cold place, the battery life could deplete by so much as half, so in very cold climates, you will very quickly run out of power.
In order for it to sustain 3 years, you will probably need to find a climates that is about 60°F (15.5556°C) in a drier location.
I hope this helped!
