AlladinOne [14]

Answer: 8

If EF is a line perpendicular to AB, then it forms four (90 degrees) angles intersecting AB. If AB is parallel to CD, and EF also intersects CD, then it form another four (90 degrees angles again. Total 90 degrees angles formed is 8.

Vesnalui [34]

They grow distinct crystal shapes because they have a loot of room and their growth and movement is not restricted, which enables them to form in whichever way they can, which is why they are so distinct.

Answer: Minerals: gypsum, corundum, graphite, argonite

Mineral Simulant : hematine, cubic zirconia

Non-mineral: menthol, sugar, DNA, glass

Explanation:

Minerals are the inorganic substances that are excavated below the earth crust by the mining process. These are made up of one or more elements combined together by chemical bonds. The examples of minerals are gypsum, corundum, graphite and argonite.

Gypsum: Gypsum is a sulfate mineral made up of calcium sulfate dihydrate. It is used as a fertilizer, used in forms of plaster and chalk preparation.

Corundum: It is a crystalline kind of aluminium oxide. It typically consists of traces of titanium, iron and chromium.

Graphite: It is a crystalline form of carbon. It is used for making pencil lead.

Argonite: It is a gaseous mineral. It is a mixture of nitrogen and argon.

Mineral simulant: It resembles the mineral. The mineral simulant can be artificial or natural.

Hematine : It is an artificial magnetic material.

Cubic zirconia: It is a hard and artificial material which imitate the diamond.

Non-mineral: A non-mineral is a substance which does not satisfy the definition of minerals.

Menthol: It is found in mint plants like peppermint and spermint. It is a nnon-mineral substance.

Sugar: It is a carbohydrate which can be define as a source of food. It is obtained from vegetables, fruits and artificial agents.

DNA: DNA or deoxyribonucleic acid is a non-mineral naturally occurring genetic material found in living beings like plant, animals, insect, humans and others.

Glass: Glass is a non-mineral. It is a supercool liquid which is heated to obtain hard amorphous solid crystalline structure. It is obtain from silica, lime and other derivatives.
