salt is not because it gets u dehydrated
Answer: True
Explanation:
Let's begin by explaining that the vision phenomenon depends on three elements: the observer, the object and the light source.
In addition, objects have pigments, which generally absorb more light than they reflect (they absorb certain wavelengths and reflect others). Therefore, the color that a given object seems to have depends on which parts of the visible electromagnetic spectrum are reflected and which parts are absorbed.
In this sense, the colours we see are in fact the wavelengths that are reflected or transmitted from the object. For example, a red object has that color because when it is illuminated whith white light, the pigments on this object abrsorb all the the wavelengths of the visible electromagnetic spectrum, except red. That is why red light is the only light that is reflected from the mentioned object.

Answer:
by changing the number of protons in the atom
Explanation:
Elements are defined by their number of protons. For example, an element with 1 proton is hydrogen, and an element with 2 protons is helium. Changing the number of neutrons or electrons in a preexisting element will not make a new element. Is is possible to create new elements, but it requires large amounts of heat and/or pressure.
