I think they are all biotic factors..hmm if not take out whichever sounds the most not fitting.
D. Oxygen and metal
They usually contain some form of metallic cation, given that carbonates are the most distributed minerals in the Earth's crust.
Hope this helped!
Answer:
Amino acid sequences
Explanation:
The proteins perform the vast majority of functions in the cells. If a gene between a human and a mouse is evolutionarily related, it means that the function they do in the cell is quite similar in both species. This is the reason why the amino acid sequence would be the most similar.
In addition, there might be certain mutations in the DNA and therefore in the RNA between this 2 sequences that encode to the same amino acid sequence. More specifically speaking, there are more than one codon that encode to the same aminoacid. Thus, 2 different DNA/RNA sequence can give the same aminoacid sequence.
The statement '(a) there are billions of galaxies in a galaxy cluster' accurately describes a relationship between two parts of the universe.
<h3>What is the solar system?</h3>
The solar system can be defined as a group of billions of galaxies that form a cluster due to gravitational forces that maintain all these celestial bodies linked together. This system contain our Sun.
In conclusion, the statement '(a) there are billions of galaxies in a galaxy cluster' accurately describes a relationship between two parts of the universe.
