Minerals are naturally-formed substances that have a specific chemical properties: abiogenic (minerals are not produced by or derived from living organisms, non-organic in origin), stable at room temperature (i.e. at 25 degrees C)
, are represented by a known chemical formula
, have an ordered atomic arrangement/structure. Coal is not classified as a mineral because it is an organic substance. Correct answer: D (coal is formed from the remains of dead plants and animals).
This most definetly false. Science thrives on evidence, and anything science based needs to proven through scientific means. And theories are constantly given evidence for or against.
In essence the key to science is to always keep and open mind. Any scientist who thinks differently is not a scientist.
<h2>Competitive inhibitor </h2>
Explanation:
Competitive inhibitor is the one which binds to the active site on the enzyme, blocking substrate molecules from the site
- Competitive inhibitor is a type of reversible inhibitor in which inhibitor binds with enzyme's active site hence inhibitor competes with substrate for binding site
- The activity of competitive inhibitor is overcome by increasing substrate concentration
- In competitive inhibition,the value of Km(Michaelis Menten constant) increases whereas that of Vmax(maximum velocity) remains unchanged
