Explanation:
Examples could be solar energy, wind energy and hydro energy. Each come from a natural resource.
The first one due to the plants using water for photosynthesis. that then produces sugar for the fruits
Bacteria and Archaea Bacteria.
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>
Answer: D) 
Explanation:
If we assume the shape of algae cell is round or sphere.
Given: The total number of algae cells spanning the field of view = 15
At 40x field of view is 
To calculate the diameter of one algae we need to divide 
by the total number algae calls spanning the field , we get
The diameter of one algae cell :
Hence, the diameter of one algae cell
