irakobra [83]

Answer:

Answer: b. developing more efficient methods of mining coal  

Coal is a combustible black or brownish black sedimentary rock. Coal is produced by the dead plant matter. It is a fossil fuels 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, sulfur dioxide and carbon monoxide gases in the environment. These gases are responsible for causing the air pollution.

b. 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.

Ion channels are a versatile group of membrane proteins that can be opened by various stimuli such as ligand binding. Once open,
Mashutka [201]

!!•••••••☆☆ Hey mate ☆☆•••••••!!

Ions are charged atoms or molecules. The plasma membrane is analogous to a capacitor, storing and separating charge. The voltage across the membrane varies from cell to cell, but a typical value is that the inside of the cell is -65 mV (millivolts) relative to the outside.

This may suggest that positive ions will flow into the cell when ion channels open, but, as mentioned in the question, the movement of ions is determined by both concentration and voltage.

This so called "electrochemical potential" can be calculated using the Nernst equation.
