Because as trials go on scientists discover more information and alter the theories and that is why they are referred to as a "theory" instead of a scientific "law"
Explanation:
<h2>Hope my answer helps you</h2>
<u>Answer</u>: D. calcium chloride
<em>Calcium chloride molecules can be ruled out as the mystery molecule</em>
<u>Explanation:</u>
<em>Artificial membranes are also called as the synthetic membranes.</em> It is created synthetically for the <em>special separation purpose in the laboratory. </em>
It is used to separate large molecules like <em>solid particles and big biological molecules like protein, DNA. </em>
They are produced from organic materials. <em>Calcium chloride contains the chloride ion and calcium ion,</em> as the chloride ion easily passes the artificial membrane so we can term <em>calcium chloride as the mystery membrane that passes the artificial membrane easily.</em>
Open systems are the most common in nature
This is a law because the math behind it is simple and makes
sense – is scientifically proven and developed and is designed to be used. If
double the force, you have double acceleration, double the mass, you get half
the acceleration. A theory is an opinion or an idea, this is a law because it
is sound and the only law for this theme, it stands true for every scenario.
<span>a...it is a fixed equation that is true for
every scenario...</span>
