Despite their differences in appearance, all bony fish have common ancestors. their fins develop from similar structures and usually have a prescribed number of bones. because of this, the large rudder-like dorsal fin of a sailfish, the poisonous dorsal fin of a catfish, and the tiny reduced dorsal fin of a puffer fish are said to be structures. a) vestigial b) analagous c) homologous d) evolutionary

The correct answer is C. Homologous

Explanation:

In biology, a homologous structure refers to a structure such as organs that are similar in two different species and that derive from a common ancestor. Also, in homologous structure, the similarity occurs in the traits but not necessarily in the purpose of the structure as each species evolves from a common ancestor and the structures also adapt to different environmental conditions. This type of structure occurs in the bony fish described as they share a common ancestor that made bony fish have similar fins but with different purposes.

yes you are doing it right great gob

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther
