What three conditions must be present for minerals to form through natural processes? why are minerals considered inorganic substances? how do oxides differ from other minerals that contain oxygen atoms? how is a sulfide different from a sulfate? what makes native elements unique?

not 100% percent sure on the first one, but

2. When a mineral is nutritionally inorganic, it means that it is without any organic (carbon-based) molecule. When a mineral is nutritionally organic, it means that it is chelated or bound to organic molecules, such as an amino acid.

3. Oxides are distinguished from other oxygen-bearing compounds such as the silicates, borates, and carbonates, which have a readily definable group containing oxygen atoms covalently bonded to an atom of another element.

4. any compound of sulfur and a metal or other electropositive element or group while sulfate is (organic chemistry) any ester of sulfuric acid.

5.Native element. Even a single native element can occur in widely diverse environments. Native iron ( kamacite ), for example, is found primarily in meteorites. The iron meteorites called hexahedrites are almost completely composed of kamacite, and in those called octahedrites it is the principal constituent.

1.For minerals to form through natural processes, the correct elements must be present in the right amounts. The physical and chemical conditions, such as temperature, pressure, and pH, must be favorable. In addition, there must be enough time for the atoms to become ordered. Otherwise the mineral grains will remain very small.

2.In most cases, minerals are considered inorganic substances because they’re not derived from or made by living matter, such as plants and animals. There are a few minerals, however, that are produced by living organisms.

3.In oxides, the oxygen atoms bond directly to one or more metals. In other minerals, such as carbonates, sulfates, and silicates, the oxygen atoms are part of molecules in which the oxygen is already bonded to another element, such as carbon, sulfur, or silicon. These molecules then bond to other elements.

4.In sulfides, sulfur atoms bond with one or more metals. In sulfates, the sulfur atoms are part of a molecule that also contains oxygen. The sulfate molecule is what bonds to other elements.

5.Native elements are unique in that they’re composed of atoms of a single element. For example, gold is composed only of gold atoms. Silver is composed only of silver atoms.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
