Q6: A
Q7:D
Q8:C

Reasoning
Q6: Based on all the other questions talking about common ancestors I deduced that to find a “common” ancestor they need to find things that are the same.

Q7: All arthropod have a exo skeleton for example a lobster or crab. They all have a head, abdomen and thorax for example ants. They all have legs with joints for example a spider.

Q7:So bones are traveled down by ancestors so the types of bones stay the same but natural selection has changed them to better fit their environment.

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.
