The least electronegative component in the electron transport chain is the Hydrogen ion.
The more electronegative is NAD+
The other component is H2O,
Next are the energy carrier molecules which are the ADP and ATP
And finally, the most electronegative is O2.
A shows the physical features of the land
Explanation:
A topographic map is a map that shows the physical features of the land area. Rivers, streams, mountains, valleys, hills and other physical features.
- A topographic map is made up of series of contour lines.
- The contour lines are lines that joins places of equal elevation.
- All places on the contour lines have the same elevation.
- Using the contour lines, we can understand the landforms in an area.
- Other map keys are used to delineate settlement patterns, streams, churches, dams and the like.
- Most topographic maps are used as base maps for making other maps.

Answer:
See the answer below, please.
Explanation:
Take as an example a light bulb inside a lamp to illuminate a room. When you plug it in a plug and turn it on, light is generated. More precisely, heat (Joule effect) is produced inside the lamp by its internal filament (conductive material) when it passes through the electrical energy, generated by the friction of the atoms that are inside it when it encounters a resistance.
Answer:
77.14 atm of pressure should be of an acetylene in the tank.
Explanation:

According to reaction, 2 moles of acetylene reacts with 5 moles of oxygen.
Moles of oxygen=
Moles of acetylene =

Volume of large tank with oxygen gas, 
Pressure of the oxygen gas inside the tank = 
..[1]
Volume of small tank with acetylene gas ,
Pressure of the acetylene gas inside the tank = 
..[2]
Considering both the gases having same temperature T, [1]=[2]



77.14 atm of pressure should be of an acetylene in the tank.
