The actual term is "effective range". That is the range where a trained shooter can consistently hit the target. For example- a 9mm pistol has an effective range of about 50 meters. However, it can shoot a bullet about 960 meters. But at that range, you will not consistently hit anything- except the earth.
It gives an indication of the spread in the values: are they all very close to the mean value or scattered across a wide range of values? That is important in determining how accurate your point estimate of the mean is.
It will be accurate at any range- however, I think you mean at what range will the point of aim and point of impact be the same. It will vary depending on the cartridge you use, barrel length, and scope height- BUT- assuming an average 30-06 load, with a scoped rifle, a 35 yard zero will have point of impact meeting point of aim at ABOUT 200 yards.

There is no such thing as a "killing range" for a firearm.
For long range and/or very accurate shooting yes, sort of. You take a deep breath, let about half of it out, then fire the gun. If you are shooting close range self defense shooting, this is not as important because you don't have to be quite that accurate.
The velocity, weight and shape of the bullet, and the density of air through which the bullet moves changes a firearm's range.
The practice itself is legal. If you're looking for a range which offers firearm rentals for their range, see the related link.
Up and down range.
The rifle greatly increased the usable range of a firearm over that of the smoothbore musket. This made changes in both the military use of firearms, and in the use of firearms for hunting. Where a smoothbore musket has an accurate range of about 50 yards, the rifle, in the hands of an experienced marksman, had a usable range of about 400 yards.
Generally, yes, although it really depends on the tolerances of the firearm.
The range of a thermometer refers to the range of temperatures it can measure accurately. For example, a thermometer with a range of -20°C to 100°C can accurately measure temperatures within that range, but may not be accurate outside of it.
No. A background check is required to purchase a firearm from a dealer. If you are renting a firearm to use at a range, they may choose to run a background check.
