Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Because there are millions of species of animals, biologists use grouping methods to classify animals. Which of the following characteristics are most important to biologists?
A
the structure of the animal’s body and the color
B
the structure of the animal’s body and the way in which it develops
C
the number of cells the animal has and the color
D
the number of cells the animal has and the way in which it develops
Explanation: 

Detailed explanation-1: -Additional information: Animal kingdom classification is an important aspect for understanding how the living organisms are related to each other. According to the Linnaeus method, species are arranged in groups according to their shared characteristics.

Detailed explanation-2: -The levels of classification are domain, kingdom, phylum, class, order, family, genus, species.

Detailed explanation-3: -Animals have been traditionally classified according to two characteristics: body plan and developmental pathway. The major feature of the body plan is its symmetry: how the body parts are distributed along the major body axis. Symmetrical animals can be divided into roughly equivalent halves along at least one axis.

Detailed explanation-4: -Organisms in the animal kingdom are classified based on their body morphology, their developmental pathways, and their genetic affinities. The relationships between the Eumetazoa and more basal clades (Ctenophora, Porifera, and Placozoa) are still being debated.
