The island fox shares a common ancestor with the gray fox, Urocyon cinereoargenteus, which is found on the mainland.

A. Both species have similar coloration and a diploid chromosome number of 66.
B. One structural difference between the two species is the reduced size of the island fox, a feature known as dwarfism.
C. The various island subspecies also differ from each other in size, number of tail vertebrae, and other characteristics.
D. The phylogenetic tree below shows the evolutionary relationships between the island fox subspecies and the gray fox.
E. Drag the labels to their appropriate locations on the tree.

Option "B & C"

B: One structural difference between the two species is the reduced size of the island fox, a feature known as dwarfism.

C: The various island subspecies also differ from each other in size, number of tail vertebrae, and other characteristics.

Explanation:

One notable difference between gray foxes and island foxes is the small size of island foxes. This character (dwarfism) was exhibited by the common ancestor of all six island fox subspecies. Note that the northern Channel Island fox subspecies are more closely related to each other than to any of the southern subspecies, and that the southern subspecies are more closely related to each other than to the northern subspecies.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !

i believe it is c: genes for body color and wing size are inherited separately from each parent.
