Answer:

4.index fossils, intrusions, and cross-cutting relationships

Explanation:

There are various geologic features or phenomenon that determines the relative ages of rocks . This geologic features or events includes index fossils , intrusions, cross cutting relationship etc. Note relative ages of rock does not give the actual ages oft the rocks but instead compares the ages of these rocks. Knowing the relative ages of rocks, one can decipher which rock is older or which one is younger. The geologic features give details on the sequence of event that happens through the formation.

Like the principle of cross cutting relationship states that the geologic feature which cut across or intrudes another geologic feature is younger than it surrounding rock.

Index fossils are remains of organisms that are widely spread. The deposition of this remains can give the sequence for deposition of the surrounding rocks which these fossils are found.

Intrusions occurs when geologic features like plutons invades another rock body. Geologically, the plutons will be younger than the surrounding or host rock.

In Pepperland, occupational success (measured by salary) is inversely proportional to the quantitative trait, "BlueMeanie-ness".
shtirl [24]

Answer:

Please see below

Explanation:

First of all we need to examine and rank all BlueMeanie-ness scores from the Pepperlanders who took the test.

Ranked scores (from lowest to highest):  8.85; 10.80; 62.98; 88.07; 90.50.

Since the rationale is: occupational success is inversely proportional to the BlueMeani-ness score, it follows that the lower the score, the higher the occupational success, measured by salary. Therefore, the individuals with their scores on the low end will have a higher salary and the individuals with the higher scores will have a lower salary.

Conclusion: The individuals with scores 8.85 and 10.80 will likely have the higher wages.

What part of the brain is being tested when a police officer asks a DWI suspect to walk a straight line and touch his nose with
Illusion [34]
The part of the brain that is being <span>tested when a police officer asks a DWI suspect to walk a straight line and touch his nose with his finger is the primary motor cortex.
The motor cortex has to do with movement and balance - so obviously, if you need to prove that you can walk a straight line, which involves both of these things, or if you need to move your finger to a certain spot, which also involves both balance and movement, that would be the correct answer.
