Answer:
The correct answer is - 1) independent 2) X.
Explanation:
independent variable is the variable or the factor that is altered or made constant or controlled to see or test the effect on the dependent variable in an experiment. Time is used in the experimental protocols in such a manner that it is considered as the independent variable.
In a graph, time is always plotted in the X-axis as independent variables are normally plotted horizontally in a graph.
Thus, the correct answer is option - 1) independent 2) x.

Answer:
Minerals.
Explanation:
Minerals can be defined as any form of naturally occurring, inorganic solid substance characterized by a crystal structure. Also, minerals are homogeneous in nature with a defined chemical composition and characterized by a crystal structure comprising of ions, atoms, or molecules in an orderly arrangement.
Generally, molecules attach on the inside of a mineral to give it shape. Therefore, the molecule of a mineral is a crystal three-dimensional regular structure (arrangement) of chemical particles that are bonded together and determines its shape.
Due to the fact that these molecules are structurally arranged or ordered and are repeated by different symmetrical and translational operations they determine the shape of minerals.
<em>Hence, inorganic, crystalline substances found naturally within earth are known as minerals. Some examples of minerals are iron, copper, aluminum, tin, coal, quartz, feldspar, mica, etc. </em>
