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.

This is also necessary to be performed on
workers after a nuclear disaster that resulted to leakage of radioactive materials
from the facility and after visiting a site that is considered to have a highly infectious
organism. Decontamination is used to
remove the material from a person or object and avoid it spreading to unaffected
areas. Decontamination is also practiced in some medical settings. </span>
If it says describe you need to say three points about the source
The genetic variation between humans and orangutans is the greatest is the right option.
Explanation:
A phylogenetic tree is illustration which shows evolutionary relationship between different species. This concept is based on Darwin's descent with modification.
Human and orangutan are 97% similar in their DNA sequences.
The difference in DNA bases shows large genetic variations in both the species.
The species are organized on the basis of traits that are changed over time as compared to their ancestors as they evolve.
Less related species will have more differences in their DNA sequence.
The phylogenetic tree formed indicates that orangutan and human are less related to each other than other species.
