What two parts make up a scientific name?
- A.
Species
- B.
Order
- C.
Class
- D.
Genus
Correct Answer(s)
A. Species
D. GenusExplanation
A scientific name is composed of two parts: the genus and the species. The genus is a broader category that groups together closely related species, while the species is a more specific designation that identifies a particular organism within the genus. This naming system, known as binomial nomenclature, was developed by Carl Linnaeus and is used to provide a standardized and universally recognized way of identifying and classifying living organisms. By using both the genus and species, scientists can communicate precisely about a specific organism and avoid confusion caused by common names, which can vary across different languages and regions.Rate this question:

What is a multicellular, nucleated (eukaryotic) heterotroph that always gains nutrition from its environment?
- A.
Animal
- B.
Plant
- C.
Amoeba
- D.
Protist
Correct Answer
A. AnimalExplanation
An animal is a multicellular, nucleated (eukaryotic) heterotroph that always gains nutrition from its environment. Unlike plants, animals cannot produce their own food through photosynthesis and rely on consuming other organisms or organic matter for energy. Amoebas and protists are also heterotrophs, but not all amoebas and protists are multicellular. Therefore, the most accurate answer is animal.Rate this question:

Scientific names are written in what language?
- A.
French
- B.
Latin
- C.
German
- D.
English
Correct Answer
B. LatinExplanation
Scientific names are written in Latin because Latin is a dead language that is no longer evolving. This means that the meaning of Latin words remains consistent over time and across different regions. Using Latin for scientific names ensures that scientists from different countries and backgrounds can understand and communicate effectively about organisms, regardless of their native language. Additionally, Latin provides a standardized system for naming species, which helps avoid confusion and allows for easier categorization and classification in the field of science.Rate this question:

A scientific name always is italicized and has the first name capitalized.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Scientific names are standardized and follow specific formatting rules. They are written in italics to differentiate them from common names and to indicate that they are in Latin or Latinized. Additionally, the first letter of the genus (first name) is always capitalized. Therefore, the statement is true as it accurately describes the formatting conventions for scientific names.Rate this question:

A cladogram shows _________________.
- A.
Defense mechanisms
- B.
The rate at which they evolve
- C.
How big organisms are
- D.
Evolutionary Relationships
Correct Answer
D. Evolutionary RelationshipsExplanation
A cladogram is a diagram that represents the evolutionary relationships among a group of organisms. It shows how different species are related to each other based on their shared characteristics and common ancestors. By analyzing the similarities and differences in traits, scientists can construct a cladogram to understand the evolutionary history and relationships between organisms. Therefore, a cladogram shows evolutionary relationships.Rate this question:

Which classification group is most inclusive?
- A.
Kingdom
- B.
Species
- C.
Class
- D.
Phylum
Correct Answer
A. KingdomExplanation
The classification group that is most inclusive is the Kingdom. In the Linnaean classification system, the Kingdom is the highest and broadest level of classification. It includes a wide range of organisms that share common characteristics and is further divided into smaller, more specific groups such as phylum, class, order, family, genus, and species. The Kingdom encompasses a larger number of species and organisms compared to the other options listed, making it the most inclusive classification group.Rate this question:

Which classification group is least inclusive?
- A.
None
- B.
Genus
- C.
Species
- D.
Kingdom
Correct Answer
C. SpeciesExplanation
The classification group that is least inclusive is the species. In the Linnaean classification system, species is the most specific and narrowest category. It refers to a group of organisms that share similar characteristics and can reproduce with one another. On the other hand, the kingdom is the broadest category, encompassing a wide range of organisms with diverse characteristics. Therefore, species is the least inclusive classification group.Rate this question:

What organism would most likely be prokaryotic, unicellular, heterotrophic, and have a spiral shape?
- A.
Prokaryotic
- B.
Eubacteria
- C.
Eukaryotic
- D.
Archaebacteria
Correct Answer
B. EubacteriaExplanation
Eubacteria would most likely be prokaryotic, unicellular, heterotrophic, and have a spiral shape. Eubacteria are a type of bacteria that lack a nucleus and membrane-bound organelles, making them prokaryotic. They are typically unicellular organisms and can obtain their energy by consuming organic matter, making them heterotrophic. Some species of eubacteria, such as spirilla, have a spiral shape. Therefore, based on the given characteristics, Eubacteria would be the most likely organism fitting the description.Rate this question:
