Answer:
A. Dinosaurs and Birds
Although the living reptiles birds are most closely related to are crocodilians (archosaurs), when it comes to their relation to dinosaurs, birds evolved from theropod dinosaurs. These theropods share over 100 traits with modern birds.
B. The pattern of branching in a phylogenetic tree reflects how species or other groups evolved from a series of common ancestors. In trees, two species are more related if they have a more recent common ancestor and less related if they have a less recent common ancestor.
C. The Jubjub bird is a dangerous creature mentioned in Lewis Carroll's nonsense poems "Jabberwocky" (1871) and "The Hunting of the Snark" (1876).In "Jabberwocky", the only detail given about the bird is that the protagonist should "beware" it. In The Hunting of the Snark, however, the creature is described in much greater depth. It is found in a narrow, dark, depressing and isolated valley. Its voice when heard is described as "a scream, shrill and high" like a pencil squeaking on a slate, and significantly scares those who hear it, including the Beaver, who "turn[s] pale to the tip of its tail" Its character traits include that it is "desperate" and "lives in perpetual passion", it "knows any friend it has met once before" and will not "look at a bribe".
