it synthesized information from diverse scientific fields in order to document evolutionary change.
The correct answer for the question that is being presented above is this one: "<span>Urochordata." </span>Lancelets have all chordate characteristics and segmentation in the adult. Tunicates (Sea Squirts), Subphylum: Urochordata Gill slits are the only chordate feature retained by the adult form.
Given what we know, the three sentences in this question all describe the properties of oceanic crust.
<h3>What is the oceanic crust?</h3>
- The oceanic crust is the outer layer of the earth, located at the bottom of the oceans.
- It contains three layers, ordered by number.
- During subduction, this remains the topmost crust.
- It is formed by the solidification of magma.
- The oceanic crust is known to be very dense.
Therefore, we can confirm that the sentences in the question describe oceanic crust given that this is the topmost crust during subduction, formed by the solidifying of magma, making it a much denser rock than the other forms of crust.
