Based on the attached Image;
The two species that are likely to have the most similar DNA base sequences
are C and D. An evolutionary tree or a phylogenetic tree, like the one shown on the image is used to indicate which ancestors gave rise to which descendants. The tree represents the evolutionary relationships among a set of organisms or groups of organisms, called taxa. The tips of the tree represents groups of descendant taxa and the nodes represents the common ancestors of these descendants.
I only have one reason but hope it helps!
Because without those bases pairing there <span>would be no structure of a DNA.</span>
Samoset and Squanto both speak using the English language.
Answer:
organ systems
Explanation:
cells combine to form tissues, tissues combine to form organs, and organs combine to form organ systems such as the digestive system.
The structure is a helix structure.
The four bases are
adenine (A), guanine (G)
cytosine (C), and thymine (T).
The pairing are
Adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine
