Answer:
in the water, plants and small organisms like plankton take up mercury through passive surface absorption or through food intake. ... Methylmercury biomagnifies through the food chain as predators eat other organisms and absorb the contaminants that their food sources contained.

Answer:
3
Explanation:
The unbalanced combustion reaction of the oxidation of propane is shown below as:-
On the left hand side,
There are 3 carbon atoms and 8 hydrogen atoms and 2 oxygen atoms
On the right hand side,
There are 1 carbon atom and 2 hydrogen atoms and 3 oxygen atoms
Thus,
Right side, must be multiplied by 3 and by 4 so to balance carbon and hydrogen.
Left side, is multiplied by 5 so to balance the whole reaction.
Thus, the balanced reaction is:-
<u>Coefficient in front of the carbon dioxide in the balanced equation - 3</u>
