This must be a universal indicator, the pH is going down everytime you add more :)
We know that domestic dogs are descended from wolves. Exactly when and how this occurred is still being studied; many experts indicate that dogs were first domesticated about 12,000 years ago, but a few DNA studies indicate a much earlier date for the split between the wolf and the dog, perhaps as long ago as 130,000 years.
Regardless of the exact timing of the divergence between wolves and dogs, one thing is true: both species display quite a bit of genetic diversity, particularly in size and coloration.In order to breed a dog of a specific size, all one has to do is choose parents with the appropriate variations. For instance, if you want to create a small dog breed, you would just breed the smallest dogs you have, then you would choose their smallest offspring to breed the next generation, and so on until you have reached the desired size.

<u>Answer:</u>
photoelectric effect and the modifications to the Rutherford model is necessary
<u>Explanation:</u>
Photoelectric effect refers to emission of electrons when a light of certain frequency falls into a metal surface or a metal atom.
Rutherford, through his alpha particle scattering experiment, proposed the emission of electrons, in which he used a thin gold foil and high energy alpha particle were directed to the foil. He suggested that any light can emit electron from any metal surface.
Answer:
Magnesium (Mg)
Explanation:
The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.
