Answer:

A Mineral is defined as an inorganic, naturally occurring, homogenoussolid, with a definite chemical composition, and ordered (crystalline) atomic structures.

Explanation:

Inorganic: Involving neither organic life nor the products created from or by organic life.

Naturally Occurring: Must be formed by natural processes, meaning a mineral cannot be manmade, manufactured, or created in a laboratory.

Homogeneous Solid: A mineral must be chemically and physically uniform down to the atomic level.

This homogeneity means that the mineral will have absolutely predictable physical properties

including hardness, density, and streak.

Definite Chemical Composition means that all occurrences of that mineral have a chemical

composition that varies within a specific limited range and the atoms that make up the mineral must

occur in specific ratios.

Ordered Atomic structure (Crystalline): The atoms in a mineral are arranged in a systematic and

repeating pattern. Glasses such as obsidian, which are disordered solids, liquids (e.g., water,

mercury), and gases (e.g., air) do not have a crystalline structure and are therefore not minerals.

<h2>Correct answer is option "A"</h2>

Explanation:

The initial concentration of the substrate(Keeping the initial substrate concentration steady permits the specialist to think about the response rates under various natural conditions. The response rates will furnish the scientist with data about the protein's capacity in various situations).
A substrate is a substance that is used to make a final product. It is changed and reformed during the process. Sometimes chemical groups are added or taken away.
In the cell, enzymes bind and change substrates into their final product. When the enzyme is bound to the substrate, it is known as an enzyme-substrate complex.
Substrate concentration is the amount of substrate present that can be turned into a product. The unit of measurement usually assigned to eggs is dozen. Substrate concentration can be measured in various ways. Since the substrates inside the cell are suspended in cellular fluid, the substrate concentration is most commonly measured in molar concentration, or molarity (M), which is moles per liter.
Hence,the correct answer is option A "the initial concentration of the substrate.
