Yes, they are.
Minerals are the result of rock metamorphic cycles and other volcanic activities that result to these mixture of different minerals. Minerals can also be the cause of some biogeochemical cycles that occurs on the earth's different spheres.

Answer:
OH LOL I DID THIS IN 7TH GRADE
Explanation:
so if i remember when the trees where white the pepper moths that where white survived more often that the black ones, then when the industrial war came the trees where covered in ash, so the white moths survived
MY SENTENCE
It shows how a change in an environment can effect a species natural selection, for example the white moths survived more than the black moths so the reproduced while the black moths where eaten by predator's, then when the environment changed and favored the black moths they survived and reproduced while the white moth got picked off by predators.
Hope this helped mate :>

Answer:
Explanation:
Carbon Bonding
The four covalent bonding positions of the carbon atom can give rise to a wide diversity of compounds with many functions, accounting for the importance of carbon in living things.
Carbon contains four electrons in its outer shell. Therefore, it can form four covalent bonds with other atoms or molecules. The simplest organic carbon molecule is methane (CH4), in which four hydrogen atoms bind to a carbon atom.
However, structures that are more complex are made using carbon. Any of the hydrogen atoms can be replaced with another carbon atom covalent bonded to the first carbon atom. In this way, long and branching chains of carbon compounds can be made . The carbon atoms may bond with atoms of other elements, such as nitrogen, oxygen, and phosphorus . The molecules may also form rings, which themselves can link with other rings . This diversity of molecular forms accounts for the diversity of functions of the biological macro molecules and is based to a large degree on the ability of carbon to form multiple bonds with itself and other atoms.
