The surface metabolism model evokes mineral
catalysts. Surface metabolism model dissolved gases in contact with
minerals lining the walls of the deep-sea hydrothermal vents and formed more
complex, organic molecules while Prebiotic soup model is molecules in
atmosphere or from meteorites condensed in the ocean which led to the formation
of more complex molecules.
When you immerse an ionic compound<span> in </span>water<span>, the ions are attracted to the </span>water <span>molecules, each of which carries a polar charge. If the attraction between the ions and the </span>water <span>molecules </span>is<span> great enough to break the bonds holding the ions together, the compound </span>dissolves<span>. </span>
He set up his periodic table by the atomic mass
Answer is: <span>the pH value(level) is the independent variable.</span><span>
</span>
Missing question: <span>We conducted an experiment where we added 0.5 g of lactose to 5 different test tubes all containing 5 different pH levels. What is the independent variable?
In this experiment pH level changes, so results depend on different pH values.
Mass of lactose is same during experiment,so t</span>he number of molecules of product formed per minute is the <span>dependent variable.</span>
