PLS HELP15. Scientists use a system called binomial nomenclature to classify organisms. For example, the
goldfish is known as Carassius auratus. Each of the two names has a different significance.
Which of the following correctly describes the meaning of the two names?
A. Carassius is a distant evolutionary ancestor of the goldfish, while auratus is a more recent
species.
B. Carassius is a group of organisms with similar behavior, while auratus is a group with
similar structures
C. Carassius is a group of organisms with similar external structures, while auratus is a group
with similar internal structures,
D. Carassius is a group of different organisms with similar structures, while auratus is a
smaller group of members that can only breed with another auratus,

The correct answer is: d. Carassius is a group of different organisms with similar structures, while auratus is a smaller group of members that can only breed with another auratus.

Explanation:

Carassius signifies the name of genus. In binomial terminology it is the generic name shared by the collection of nearby families. In this case, Carassius is a genus in the family of ray-finned fishes. Auratus signifies the types of the fish and it is detailed exclusive epithet within the type. Carassius is a type in the ray-finned fish family Cyprinidae. Maximum types in this genus are usually identified as crucian carps, however this tenure often precisely denotes to C. carassius. The most well known is the goldfish (C. auratus).
