In an experiment, a researcher measures the mass of an object and gets the following results: 6.08 g, 6.07 g, 6.13 g, 6.09 g. Th
yawa3891 [41]

Considering the definition of accuracy adn precision, the results are accurate and precise.

<h3>Definition of accuracy and precision</h3>

Accuracy is the degree of closeness of the value of the measurements with respect to the real value of the magnitude. The closer a measurement is to the true value, the more accurate it is.

On the other hand, precision is defined as the proximity between the measured values ​​in repeated measurements, under specified conditions; that is, there is more precision the closer the values ​​of different measurements ar

In summary, accuracy is how close a measurement is to the true value, while precision is how close the values ​​of several measurements are to a point.

Accuracy and precision are independent of each other. The results in the values ​​of a measurement can be precise and not exact (and vice versa).

<h3>This case</h3>

In an experiment, a researcher measures the mass of an object and gets the following results: 6.08 g, 6.07 g, 6.13 g, 6.09 g.

So, the measurement is quite precise, since the results of each individual measurement are quite similar.

Also, the actual mass of the object is known to be 6.10 g, so the measurement can be considered accurate.

In summary, the results are accurate and precise.

Materials move within the cell 's cytosol by diffusion, and certain materials move through the plasma membrane by diffusion. ... Diffusion: Diffusion through a permeable membrane moves a substance from an area of high concentration (extracellular fluid, in this case) down its concentration gradient (into the cytoplasm). Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.The cell membrane controls what goes in and out by having protein channels that act like funnels in some cases and pumps in other cases. ... Active transport requires energy, because protein machines actively grab molecules on one side of the membrane and push them through to the other side
