Answer:
by developing more efficient methods of mining coal
Explanation:
Coal is a combustible black or brownish black sedimentary rock. Coal is produced by the dead plant matter. It is a fossil fuel that is used for generating electricity in the thermal power plants, used as cooking fuel, and fuel in automobiles. The burning of the coal results in the liberation of carbon dioxide, sulphur dioxide and carbon monoxide gases in the environment. These gases are responsible for causing the air pollution.
Developing more efficient methods of mining coal is not a conservation tactic related to coal consumption because the more the efficient mining will promote the excavation of the coal, which will further contribute to its extensive consumption and air pollution.
Classification is subject to change because science is an evolving subject. New things are discovered every year and thus changing the way we understand the world around us.
Answer:
Glycocalyx
Explanation:
Glycocalyx is carbohydrate rich (glycoprotein + glycolipid) coating that is found in outer surface of cell membrane of many prokaryotic and eukaryotic cells specially bacteria.
Glycoprotein=Carbohydrate + Protein
Glycolipids= Carbohydrate + Lipids
Glycocalyx provied a barrier between cell and its surrounding, adhesion and provide protection in bacteria. In eukaryotes it can be used to identify cells.
