Answer:
The gene, or sequence of DNA, ultimately determines the unique sequence of amino acids in each peptide chain. A change in nucleotide sequence of the gene's coding region may lead to a different amino acid being added to the growing polypeptide chain, causing a change in protein structure and therefore function
Explanation:
The answer to this would be layer D because temperatures in the mantle range from 500-900 degrees celsius
I think only w and 5 can attract a magnet but not sure
Because a hypothesis is different from the research question, research is usually required before you make a hypothesis. A hypothesis is a prediction of the test that is about to incur. Without the research the people doing the test would not know what to be looking for or how to setup the test. Because of the reason;
I assume the answer is, after generating an idea from an observation.
"Viruses straddle the definition of life. They lie somewhere between supra molecular complexes and very simple biological entities. Viruses contain some of the structures and exhibit some of the activities that are common to organic life, but they are missing many of the others. In general, viruses are entirely composed of a single strand of genetic information encased within a protein capsule. Viruses lack most of the internal structure and machinery which characterize 'life', including the biosynthetic machinery that is necessary for reproduction. In order for a virus to replicate it must infect a suitable host cell".
