A graph of coal reserves in the United States versus time slopes downward. This indicates that coal production could have ______
rjkz [21]
The correct answer is:  [B]:  "decreased" .
________________________________________________________
<u>Note</u>:
________________________________________________________
        In a graph of "coal reserves in the United States" vs. "time" ; 

→ the "time" is the "independent variable" that belongs on the "x-axis" .

→ The quantity or amount of "coal reserves in the United States" is the "dependent variable" that belongs on the "y-axis" . 

       If the graph "slopes downward" ;  this would indicate a "decrease" in the amount/quantity of "coal reserves" over "time" .  

→  As the value of "x" increases — "time" increases — and; as "x" increases, the value of "y" {the amount/quantity of "coal reserves"} decreases.  

→ This would be represented by a "downward sloping" graph;  

→  and, among the answer choices given, could indicate that coal production:
_______________________________________________________
                     →  "decreased" ;    
_______________________________________________________
→  which is:  Answer choice:  [B]:  "decreased" .

PLEASE HELP!!!!!!!

1. The correct answer is; are body cells is going to shrink. <span>Salty seawater is a hyperosmotic solution, meaning that it has more solutes than the cell inside. The water will move (from the cell) via osmosis in order for the solutions to reach equilibrium. Also, salty solution exerts more pressure on the of the cell, so the cell will shrink.</span>
<span>
2. The correct answer cells in the fish will stay the same size. This will occur because both solutions, freshwater lake and river have similar (or equal) solute concentrations. Those solutions are called isosmotic. There is no movement of water or the solutes, so the cell stays the same.</span>

3. The correct answer is to swell. <span>This will happen because sea star egg has the same solute concentration as its first environment-ocean meaning that this solution is hyperosmotic comparing to the lake (ocean is saltier than the lake, it has more solutes). When you put the sea star egg in the lake, the water from the lake will move (via osmosis) into the egg, to reach equilibrium. Water will cause the cell to swell.</span>

mrs_skeptik [129]
<span>The cell has 1% concentration of the salt. The external environment is highly concentrated with 25% saline solution. This will lead to release of water outside the cell, by passive diffusion from a region of high conentration of solvent to lower concentration. Thus, the cell will shrink.</span>
