Let's consider water.
Regardless of what form it turns into, the mass should remain the same.
It's the same H20.
Add some heat and it becomes water vapor,
cool it down a bit and it becomes ice.
if you make it just right, it becomes water again.
A chemical change would involve the one or more element(s) changing into a different solution all together.
It cannot be reversed unless you use electrolysis or some other method.

hope this helps :)
A. build proteins
Explanation:
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins
A. The number of valence electrons determines how it reacts with other elements.
<em>One to three valence electrons</em>: The element behaves like a metal and reacts with non-metals.
<em>Five to seven valence electrons</em>: The element behaves like a non-metal and reacts with metals.
<em>Four valence electrons</em>: Elements at the top of the Group are non-metals, while those at the bottom are metals.
<em>Eight valence electrons</em>: Elements have a complete octet, so they are generally unreactive.
I think the correct answer from the choices above is the first option. I would say the ink from pentel pen would yield a better chromatogram. This is because it will have the least viscosity among the three choices. Hope this answers the question. Have a nice day.
