Chapter 20: Problem 21

What is the correct way to format a two-word scientific name? a. Italicize both words. Both words are lower case. b. Italicize both words. The first word should be capitalized. The second word should be lower case. c. Italicize both words. Capitalize both words. d. Underline both words. Capitalize both words.

Short Answer

Expert verified
Option b: Italicize both words. The first word is capitalized, and the second word is lower case.

Step by step solution

01

Understand the Binomial Nomenclature

The scientific naming of species follows a system called binomial nomenclature. This system uses two words to name a species.
02

Identify the Formatting Rules for Binomial Nomenclature

In binomial nomenclature, the first word refers to the genus and the second word refers to the species. The correct format requires the genus name to be capitalized and the species name to be in lower case. Both words should be italicized.
03

Analyze Each Option

a. Both words are lower case and italicized, which is incorrect. b. The first word (genus) is capitalized, the second word (species) is lower case, and both are italicized, which is correct.c. Both words are capitalized and italicized, which is incorrect.d. Both words are underlined and capitalized, which is incorrect.
04

Choose the Correct Answer

Based on the analysis in Step 3, option b is the correct way to format a two-word scientific name.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Scientific Names
In biology, every organism is given a unique scientific name. This helps scientists accurately identify and communicate about species worldwide. Scientific names are standardized and agreed upon internationally, avoiding confusion that common names might cause. For instance, a 'panther' could refer to different animals depending on the region, whereas Panthera onca specifically identifies a jaguar.
Scientific names are vital for organizing and understanding biodiversity. They consist of two parts following a set of established rules. Without these names, it would be much harder for scientists to keep track of the millions of species on Earth.
Genus and Species
Scientific names consist of two parts: the genus and species.
This naming system is called binomial nomenclature, and it uniquely identifies each species.

Genus: The first part of the name represents the genus. This groups species that are closely related. For example, in Homo sapiens, 'Homo' is the genus.

Species: The second part identifies the species within the genus. It shows the particular organism. In Homo sapiens, 'sapiens' refers to our specific species within the Homo genus.
Together, this two-part name ensures that each species has a distinct and universally recognized identifier.
Taxonomy Rules
Taxonomy governs the naming and classification of organisms and establishes the rules for formatting scientific names. Here are the key rules:
  • Genus Capitalization: The genus name must always be capitalized.
  • Species Lowercase: The species name should always start with a lowercase letter.
  • Italicization: Both the genus and species names must be italicized when typed. If handwritten, they should be underlined instead.
These rules ensure consistency and clarity in identifying species. By following these guidelines, scientists worldwide can effectively communicate about different life forms without ambiguity.

Scientists apply the concept of maximum parsimony to do what? a. describe phylogenies accurately b. eliminate analogous traits c. identify mutations to DNA codes d. locate homoplasies

How is systematics related to phylogeny? a. Systematics provides guidelines that scientists use to describe the relationships of organisms. b. Scientists use systematics programs to put together the phylogeny of an organism. c. In systematics, scientists use combined data based on evolutionary relationships from many sources to put together the phylogeny of an organism. d. Systematics is a process used to put together the phylogeny of an organism.

Judeo-Christian religious texts explain that the Earth and all the organisms on Earth were created in seven days. Why is this not a valid scientific hypothesis?

Describe how organisms are classified in the taxonomic classification system. a. The taxonomic classification system uses a hierarchical model to organize living organisms. At each sublevel, the organisms are more similar. b. The taxonomic classification system uses a hierarchical model to organize living organisms. At each sublevel, the number of organisms increases. c. The categories in the taxonomic classification system are organized from smaller, more specific categories to larger categories. d. In the hierarchal model for the taxonomic classification system, from the point of origin, the groups become less specific.
