Unit 8 Target 1: Classification And Cladograms

The correct answer is Millipede because it matches all the given characteristics. Millipedes have many more than 8 jointed legs on a segmented body, with 2 pairs of legs attached to each body segment. They also lack biting jaws. Dragonflies have 6 legs, sea stars have multiple arms instead of legs, and slugs have a soft body without segmented legs.

According to the cladogram, Species F is the most recent common ancestor to Species A and Species E. This is because Species F is the closest shared ancestor that branches off before the split between Species A and Species E. The cladogram shows that Species F is connected to Species A and Species E through separate branches, indicating that it is the common ancestor to both species.

Chimpanzee and gorilla share the most recent common ancestor because they belong to the same family. Taxonomic classification is based on evolutionary relationships, and organisms that share the same family are more closely related than those in different families.

The organisms that possess these traits are from the kingdom Plantae. This is because they have eukaryotic cells, which means their cells have a nucleus and other membrane-bound organelles. They are also photosynthetic, meaning they can use sunlight to produce their own food through the process of photosynthesis. Additionally, they have cellulose cell walls, which provide structural support to the cells.

Lions, cheetahs, and tigers share the most specific taxonomic level of Family. This is because they all belong to different genera (Panthera for lions and tigers, Achinonyx for cheetahs), but they are all classified under the same family, Felidae.

Based on their scientific names, the most accurate conclusion about the relationship of Homo erectus and Homo neanderthalus is that they are genetically similar. Scientific names are given to organisms based on their similarities in genetic makeup and physical characteristics. Therefore, the fact that both Homo erectus and Homo neanderthalus have similar scientific names suggests that they share genetic similarities and are closely related to each other.

The most likely conclusion about the evolutionary relationship between these organisms is that the wood frog and bullfrog share a more recent common ancestor than the western toad and the spadefoot toad. This can be inferred from the fact that they are all placed in the same class and order, indicating a closer evolutionary relationship between the wood frog and bullfrog.

A multicellular, nonmotile, autotrophic organism would be classified in the kingdom Plantae. This is because the characteristics mentioned are commonly associated with plants. Plants are multicellular organisms that cannot move on their own and are capable of producing their own food through the process of photosynthesis. Therefore, based on these characteristics, it can be concluded that the organism in question belongs to the kingdom Plantae.

The level of biological taxa that includes Chordata, Molluska, Echinodermata, Arthropoda, and Cnidaria is Phylum. Phylum is a taxonomic rank below the kingdom and above the class level. It represents a group of organisms that share certain fundamental characteristics and are classified together based on those characteristics. In this case, Chordata, Molluska, Echinodermata, Arthropoda, and Cnidaria all belong to the same phylum because they share certain structural and developmental characteristics.

Based on the given characteristics of the new invertebrate, it can be determined that it belongs to the arachnid group. Arachnids are characterized by having an exoskeleton, two body segments, eight legs, and jointed appendages. Additionally, the presence of chelicerae and multiple eyes further supports the classification of this new invertebrate as a scorpion, which is a specific type of arachnid. Therefore, the correct answer is Scorpion (Arachnida).

The entomologist should give the beetle a new species name not used in the genus Tenebrio because although the beetle closely resembles other darkling beetles of the genus Tenebrio, it has been identified as a new species. Giving it a new species name will help differentiate it from other species within the same genus and avoid confusion in taxonomy.
