Answer:
Georgia is the world's leading producer of Kaolin (china clay).
Explanation:
Kaolin or china clay contains the mineral kaolinite mainly. It also contains varying amounts of other minerals like muscovite, feldspar, quartz, etc. In order to prepare it for commercial use, the clay in its natural form is then chemically treated and washed with water to remove the other minerals.
Kaolin is extensively used in the ceramic industry and the paper-coating industry. The high fusion temperature and white burning characteristics are used in the ceramic industry for the manufacture of chinaware, porcelain, and refractories. In the paper-coating industry, the kaolin is mixed with the cellulose fiber in the paper sheet. This gives the paper its color, opacity, and printability. It is also used as a pigment additive in paints, as a filler in plastic and rubber compounds, and in pharmaceuticals.
Natural selection is the process by which individuals who are best suited to the environment tend to leave (on average) more offspring than others.
Evolutionary changes take place over many generations and through millions of years of natural selection. For the genes to survive, they must be among the strongest.
Answer:
abiotic components or abiotic factors are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems.
Answer:
The order of events would be:
4.Threshold stimulus, Na+ channels open. This is the first event
5.Na+ influx, Depolarization. Second event
2.Na+ channels close, K+ channels open. This is the third event
1.K+ efflux, Repolarization. Fourth event
3.Hyperpolarization, K+ channels close
Explanation:
In resting state, the membrane is negative inside, and K+ concentration is higher than outside. Na+ concentration is higher outside instead.
Sodium influx is responsible for membrane depolarization. It's the event to produce the action potential. When sodium channels are closing, potassium channels open and K+ go outside until repolarization occurs. But now we have both ions in different sides of the membrane, and this can't be stimulated again to produce other action potential. The membrane will remain refractory to respond to the adequate stimulus until ions migrate to their original sites. This is Na+ outside, and K+ inside. This is responsibility of the Na+/ K+ pump, that uses ATP to pump Na+ out, and K+ in. Once both ions had been relocated in the membrane, this is ready to receive a correct stimulus to produce a new action potential.

idk if that is what u wanted
