When repeated measurements of the same quantity are very close to one another they are termed as precise measurements.
<u>Explanation:
</u>
An experiment is repeated two to three times and the outcomes were checked to have similar values to attain precision of the measurements. The accuracy and precision are the important in attaining correct measurements.
The accuracy is the closest true value obtained from the measuring instrument. But to get precise results, the measurements were taken repeatedly and then analyzed whether the values obtained are similar or varying significantly.
If the repeatedly measured values are very close to one another that means the measured quantities are precisely taken. All the values are precise in nature.
The answer would be D.) Genetic Engineering
Missing question:
<span>a) mass.
b) diameter.
c) distance from the Sun.
d) density.
Answer is: </span>d) density.
Earth has the highest density of all eight planets in the Solar System, density of the Earth is 5.514 g/cm³<span>.
</span>The four inner planets,<span> closest to the Sun, are all </span>terrestrial planets, which means they are composed of silicate rocks and metals and four outer planets<span> are </span>gas giants, they<span> are composed of hydrogen, helium and water.
</span>Earth is third planet from the Sun.
You must perform stoichiometry! always divide by what you already have (this will make since in a moment)
5.2g Carbon | 1 mole/12.01g/mole | 6.02 x 10^23 atoms/1 mole | = atoms in Carbon
above is the basic stoichiometry set up but your calculation should be (5.2g/12.01g) x (6.02 x 10^23) = 2.61 x 10^23 atoms
