The geologic features that help scientists to determine the relative ages of rocks by their positions include index fossils, intrusions, and cross-cutting relationships (Option d).
<h3>What does geological age mean?</h3>
The expression geological age refers to the relative age of a given rock and or fossil (i.e. a piece or trace of dead organism) in a geological time scale.
In conclusion, the geologic features that help scientists to determine the relative ages of rocks by their positions include index fossils, intrusions, and cross-cutting relationships (Option d).

2. The evolutionary process through which new species emerge
Answer:
The thoracic cavity is "Superior" to the abdominopelvic cavity. Superior ... If an incision cuts the heart into right and left parts, a "Sagittal" plane of section was used
Explanation:
The thoracic cavity is mainly located in the chest region which also have neck and the diaphragm in it. In the thoracic cage the thoracic organs are safely placed. The thoracic cavity lies above the abdominopelvic region. The sagittal plane is the vertical plane which runs from the front to back of the body. The sagittal plane helps in splitting of two equal halves like the left and right one.
I believe the answer is restriction organism.
