<span>Her data suggested that DNA is a helical structure that has two strands attached in the middle by the phosphate bases. That was the necessary information, needed to complete an accurate model of the structure of DNA. She also was the first one to announce that the phosphate units are located in the external part of the DNA and that the amount of water found in the molecule is in accordance with other parts of it.</span>
Answer:
b
Explanation:
some are the same while others are different (traits)
The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.
The molecular data are not found here but rabbits and whales are linked with the dogs and pigs in a cladogram due to evolutionary relationships.
<h3>What is a cladogram?</h3>
A cladogram is a graphical representation used to evidence the relationships between organisms due to a common evolutionary origin.
A cladogram is composed of a root that represents the common ancestor of the group and nodes where taxonomic groups diverge.
Cladograms based on molecular data use the homology level of nucleotide sequences of the genome to determine evolutionary relationships among individuals of different species.
In conclusion, rabbits and whales are linked with dogs and pigs in a cladogram due to evolutionary relationships.
