<span>molecule
Compounds are composed of molecules. </span><span>Compounds are not necessary to form mixtures. There is an “or” in the said definition and certain authors to support this claim. These includes examples that can state clearly this argument, table salt as a mixture of independent elements, Na and Cl. Brass is composed of zinc and copper. Steel is from carbon and iron. Lastly, you can have gold, nickel and palladium or platinum to form white gold. </span>
Do you have any answer choices?
Answer:
Algae or other microorganisms
Explanation:
Well with the ph above 7 that means the water is more of a base due to the salt within the water. the decrease in the ph is due to gloabal warming and the melting of ice which is somewhat diluting the water more. the wildlife within the ocean has been there since you or i so some creatures have developed a very specific habbitat and less salt withing the water could have effects on them. one such instace is if the organism needs a lot of salt. a decrease in salt would mean that their cells would bloat with water until they explode. this would obviously hurt the species as a whole and in turn effect the whole food chain.
Answer:
Enzymes are catalysts, meaning that they lower the activation energy. Lower activation energy allows for a faster process so enzymes speed up chemical reactions.
Explanation:
Enzymes are usually proteins that act on molecules called substrates and bind to a region of the enzyme, called the active site. This is the site where catalytic function occurs. The catalytic function is to reduce the activation energy necessary to start biochemical reactions, allowing the formation of a product to be quicker.
