Answer:
I think scientists use these types of structures to determine how organisms are related by:
establishing associations between related common ancestors.
Explanation:
The reason behind this answer is that in the first place, scientists can evaluate the source origin of all organisms and find out if they share a common ancestor based on the organization they have. This can be very useful considering certain organisms can share characteristics. So, they might be located near one to the other.
Answer: A mutation Changes by its mistake in the DNA which results in the wrong amino acid being incorporated into a protein because of change, that single DNA sequence change, results in a different amino acid codon which the ribosome recognizes.
Explanation:
A mutation changes the instructions of a gene, which can also change the protein. Sometimes this change makes it so the protein can't do its job as well. And this is what happens with sickle cell anemia. A mutation in the hemoglobin gene changes the hemoglobin protein in a way that causes sickle cell anemia.
Organism and organ system
<span> The highest ranked category or the highest taxonomic rank of organisms is a domain. Carl Woese designed three-domain system of taxonomy which includes Eukarya, Bacteria and Archea, and they differ in rRNA. The first includes all living organisms that have a nucleus and membrane-bound organelles and multicellular organisms. Other two are prokaryotic microorganisms or single-celled organisms whose cells have no nucleus. </span>
