If a rifleman's gunsight is adjusted correctly but he has shaky arms, he might shoot bullets scattered widely around the bull's-eye target. draw a sketch of the target with the bullet holes. does this show variation (lack of precision) or bias

Lack of precision

Explanation:

Precision is a term used to describe a situation that is close to a correct measurement, but does not correctly measure that measurement. In addition, for a situation to be precise, it is necessary that this situation be repeated and that every repetition shows the same result.

If a situation is repeated and shows different results, it means that this situation is lacking in precision. An example of this can be seen in the question above where a sniper shoots towards a target, does not hit the target and his shots hit places with different distances. You can see a representation of this in the figure below.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
