The evolutionary relationships and heredity of a group of organisms is called its phylogeny. Phylogenetic studies attempt to discover phylogenies. The basic approach is to use similarities based on shared inheritance to determine relationships. As an example, species of Pereskia are trees or bushes with prominent leaves. They do not obviously resemble a typical leafless cactus such as an Echinocactus. However, both Pereskia and Echinocactus have spines produced from areoles (highly specialised pad-like structures) suggesting that the two genera are indeed related.
What does the phylogeny of a group represent?
A: relationships and heredity

The New Haven Division buses follow routes that had originally been covered by trolley service. Horse-drawn steetcars began operating in New Haven in the 1860s, and by the mid-1890s all the lines had become electric. In the 1920s and 1930s, some of the trolley lines began to be replaced by bus lines, with the last trolley route converted to bus in 1948. The City of New Haven is in the very early stages of considering the restoration of streetcar (light-rail) service, which has been absent since the postwar period.
What advancement was made to New Haven trolley lines in the mid 1890's?
A: all the lines had become electric

Due to historically close ties with France, French literature came to constitute the major Western influence on Ottoman literature throughout the latter half of the 19th century. As a result, many of the same movements prevalent in France during this period also had their Ottoman equivalents: in the developing Ottoman prose tradition, for instance, the influence of Romanticism can be seen during the Tanzimat period, and that of the Realist and Naturalist movements in subsequent periods; in the poetic tradition, on the other hand, it was the influence of the Symbolist and Parnassian movements that became paramount.
The poetic tradition had its biggest influence on what Ottoman literary movements?
A: the Symbolist and Parnassian movements

There are four categories of terra nullius, land that is unclaimed by any state: the small unclaimed territory of Bir Tawil between Egypt and Sudan, Antarctica, the oceans, and celestial bodies such as the Moon or Mars. In the last three of these, international treaties (the Antarctic Treaty, the United Nations Convention on the Law of the Sea, and the Outer Space Treaty respectively) prevent colonization and potential statehood of any of these uninhabited (and, given current technology, not permanently inhabitable) territories.
Where was the United Nations Convention located?
A:
unanswerable
