Homology is simply known to be similar as a result of shared ancestry. The type of evidence for the theory of evolution is homologous structures.
- There are two types of homologous structures. They are phylogenetic/evolutionary between species and serial/iterative or homonomy that takes place within individuals.
A good example of homologous structures are the limbs of humans, cats, whales etc. These structures are due to divergent evolution.

The taxonomic classification that is the same for a humpback whale and a basking shark is Phylum.
<h3>What is Taxonomic Classification?</h3>
We want to find Which taxonomy classification are the same for a humpback whale and a basking shark.
A chordate in the animal kingdom is referred to as Kingdom Animalia of the phylum Chordata. This phylum is one that includes all the vertebrates and subphyla tunicates and cephalochordates.
Chordates have peculiar characteristics such as notochord, pharyngeal slits, nerve cord, and a tail.
Therefore, we can conclude that the taxonomic classification that is the same for a humpback whale and a basking shark is Phylum.

The resultant displacement that John Traveled is; 5 meters
<h3>How to find the displacement?</h3>
We are told that;
- He walked 3 meters north
- Then he walked 4 meters east
Distance is defined as the total movement of an object without any regard to direction. Whereas, Displacement is defined as the change in position of an object.
Thus, distance would have been 3 + 4 = 7 m. However, we are dealing with direction here as regards displacement and as such this will be gotten by Pythagoras theorem.
Displacement = √(3² + 4²)
Displacement = 5 meters
Complete question is;
John walks 3 m north and then 4 m east. What is the resultant displacement?
