My guess is that water is a liquid and not a solid, or a gas. It can be heated by us or by the suns rays, which if done by the suns rays the water azorbs the light rising the temp to the point of boil which then makes the water evaporate into the air, and thus making cloud in the sky that we see all the time thus when the clouds become big enough it begins to rain. ( also called the water cycle)
If the number of rats decrease, snakes would look for another prey.
The H+ in a solution that has a Ph of 8.73 is calculate as follows
Ph is always = - log (H+)
H+ = 10^-Ph
H+ is therefore = 10 ^- 8.73
H+ = 1.86 x10^-9 M
The electron microscope uses a beam of electrons and their wave-like characteristics to magnify an object's image, unlike the optical microscope that uses visible light to magnify images.
