The gray squirrel, Eastern fox squirrel, and red squirrel are all different species of squirrels. Why is having a scientific name for each species of an organism important?
To prevent existing named organisms from having their names changed as they become extinct
To keep the classification system from being altered as new organisms are discovered
To allow organisms to be placed in many classification levels at the same time
To standardize the naming and organization of organisms to avoid confusion
Organisms are classified today using the Linnaean system, and the following table shows the taxonomic classification of two marine organisms living along the Pacific Coast.
Taxonomic classification is important to marine biologists because it provides a way to -
prove that marine evolution occurs
discover and name every marine organism on Earth
designate Latin as the universal language of marine biology
identify marine organisms and find evolutionary relationships between them
Scientists around the world use a standardized taxonomic system. Scientists use a standardized taxonomic system because
(a)
Adult mountain lions (Puma concolor) are almost 2 meters long. They have a black spot over each eye. The common names used throughout the United States for this species are listed below.
Why is it best for scientists to use the name from the standardized taxonomic system?
The standardized name differentiates mountain lions and pumas.
The standardized name is less descriptive of the animal that has been observed.
Communication with other scientists about mountain lions will be reduced.
All scientists will be using one name for mountain lions.
The Linnaean taxonomic system classifies organisms into divisions called taxa. If two organisms belong to the same taxonomic group, they are related. Similarity at which of these levels indicates the closest relationship?
(a)
A dichotomous key for identifying fish is shown.
Based on this key, which two fish have eyes located on either side of their head and are not spotted?
Glassy sweeper and squirrelfish
Glasseye snapper and spotted eagle ray
Spotted goatfish and bandtail puffer
Peacock flounder and glassy sweeper
Many tree frog populations are threatened due to habitat loss. In an effort to promote conservation, tree frogs may be bred in captivity. A zoo acquired male and female tree frogs from two different populations. In the zoo, the tree frogs were able to successfully mate within their own population, but breeding attempts between the two populations were unsuccessful.
Based on this information, which statement correctly describes the relationship between the two populations of tree frogs.
They are in the same species but different kingdoms.
They are in the same class but different phyla.
They are in the same family but different orders.
They are in the same genus but different species.
A student used a microscope to study four members of the phylum Ciliophora. Members of this phylum move when propelled by hundreds of tiny cilia.
Although these organisms belong to the same phylum, they are classified as different -
families
species
kingdoms
orders
The relationships among different orders of millipedes are shown in the cladogram.
Based on this cladogram, which statement best describes relationships among millipede orders?
Stemmiulida is more closely related to Merocheta than Penicillata is to Merocheta.
Spirostreptida is more closely related to Glomerida than Sphaerotheriida is to Glomerida.
Polyzoniida is more closely related to Glomeridesmida than Sphaerotheriida is to Glomeridesmida.
Merocheta is more closely related to Glomeridesmida than Glomerida is to Glomeridesmida.
Simple leaves have a single leaf on a petiole, or stem, while compound leaves have more than one leaflet on a petiole. This unknown leaf can be identified using the dichotomous key.
Which tree does the unknown leaf come from?
Ungnadia speciosa
Sophora secundiflora
Salix nigra
Quercus laceyi
A team of students encounters an unknown organism in a field while conducting a biodiversity study. Some students think the organism is a plant, while others think it is a fungus.
Which question should the students investigate to classify the organism correctly?
Is there a cell wall around the cells of the organism?
Does the organism perform photosynthesis?
Is there nervous tissue present in the organism?
Does the organism reproduce sexually?
Which list correctly identifies characteristics that protists share with animals?
Five general characteristics of organisms in kingdoms Plantae or Fungi are listed in the box.
Which table correctly lists the characteristics of the organisms in the two kingdoms?
A student wants to use the Venn diagram below to show the characteristics of two kingdoms of organisms. The characteristics that the two kingdoms share will be listed in the shaded area where the circles intersect.
Which of these is a characteristic that the student should list in the shaded part of the diagram?
Heterotrophic
Mobile
Prokaryotic
Multicellular
The diagram shows taxonomic groups and a major distinguishing characteristic of all but two of them.
Which characteristic will be used to complete the chart ?
