Multiple Choice

Why do biologists use Classification?

• To create new species in the lab.
• To study the weather patterns in ecosystems.
• To determine the age of organisms.
• Biologists use classification to organize and categorize living organisms.

Multiple Choice

The scientific study of how living things are classified

• Ecology
• Genetics
• Taxonomy

Multiple Choice

Carolus Linnaeus devised a naming system that placed organisms in groups based on their observable features. What was this naming system called?

• Taxonomic hierarchy
• Genetic classification
• Ecological nomenclature
• Binomial nomenclature

Multiple Choice

What is the first word in an organism's scientific name?

• Species
• Order
• Family
• Genus

Multiple Choice

What is the second word in an organism's scientific name?

• genus name
• kingdom designation
• species

• family classification

Multiple Choice

A group of similar organisms that can mate with each other and produce offspring that can also mate and reproduce

• Species
• Genus
• Order
• Family

Multiple Choice

What language did Linnaeus use?

• French
• Greek
• German
• Latin

Multiple Choice

Why did Linnaeus use Latin for his naming system?

• To ensure clarity and consistency in scientific naming.
• To create a unique language for scientists.
• To simplify the naming process for common people.
• To promote the use of English in science.

Multiple Choice

What basic functions do scientific names serve?

• Scientific names serve to uniquely identify species, provide a universal naming system, and facilitate scientific communication.
• Scientific names are primarily for aesthetic appeal.
• Scientific names are only relevant in local contexts.
• Scientific names are used for marketing purposes.

Multiple Choice

A dichotomous key is

• A system for organizing library books by genre.
• A guide for cooking different types of food.
• A tool for identifying organisms through a series of choices based on characteristics.
• A method for classifying plants based on their height.

Multiple Choice

How many levels are there in the classification of living things?

• 5
• 10
• 12
• 8

Multiple Choice

The more classification levels that two organisms share, the...

• more characteristics they have in common

• greater environmental adaptability
• similarity in evolutionary relationships
• increased genetic diversity

Multiple Choice

List the 8 levels of classification in order from largest to smallest.

• Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
• Domain, Kingdom, Phylum, Order, Class, Family, Species, Genus
• Kingdom, Phylum, Class, Order, Family, Species, Genus, Domain
• Domain, Kingdom, Class, Order, Family, Genus, Species, Subspecies

Multiple Choice

What are the 3 domains of living things?

• Mammals, Reptiles, Birds
• Bacteria, Archaea, Eukarya
• Plants, Fungi, Protista
• Viruses, Bacteria, Fungi

Multiple Choice

How are organisms placed in domains?

• based on cell type, ability to make food, and number of cells.

• based on their diet and behavior.

• by the habitat of the organisms.

• based on their color and size.

Multiple Choice

Bacteria are unicellular

• and multicellular organisms.

• prokaryotic organisms.

• eukaryotic organisms

• protists

Multiple Choice

How many cells does Archaea have?

• Two cells
• Multiple cells

  (multicellular)

• No cells
• One cell

  (unicellular)

Multiple Choice

What does the Greek word Archaea mean?

• Complex or advanced
• Fossilized or extinct
• Modern or contemporary
• Ancient

Multiple Choice

How does domain Archaea differ from bacteria?

• Archaea have a nucleus while bacteria do not.
• Archaea and bacteria have identical genetic sequences.
• Bacteria can survive in extreme conditions while Archaea cannot.
• Archaea differ from bacteria due to their structure & chemical makeup

Multiple Choice

Organisms in the domain Eukarya are eukaryotes, which means they are

• organisms without a nucleus
• exclusively single-celled organisms
• organisms with a nucleus

• bacteria

Multiple Choice

Which domain are protists, fungus, plants, and animals in?

• Prokarya
• Archaea
• Bacteria
• Eukarya

Multiple Choice

Why are protist known as the odds and ends kingdom?

• Protists are primarily bacteria that thrive in extreme environments.
• Protists are a type of plant that produces flowers and seeds.
• Protists are exclusively multicellular organisms that form complex tissues.
• Protists are known as the odds and ends kingdom because they include a diverse array of organisms that do not fit into the other established kingdoms.

Multiple Choice

How do fungi obtain food?

• Fungi obtain food by hunting and trapping small animals.
• Fungi use photosynthesis and are autotrophs.

• Fungi obtain food by absorbing nutrients from their surroundings, which makes them heterotrophs.

• Fungi rely on sunlight to generate energy for growth.

Multiple Choice

How many cells do plants have and how did they obtain food?

• Plants are unicellular and get food from the soil.

• Plants are multicellular and obtain food through photosynthesis (autotrophs).

• Plants are multicellular and obtain food through digestion.

• Plants are multicellular and rely on animals for food (heterotroph).

Multiple Choice

What characteristics do organisms in the animal kingdom share?

• Multicellular, heterotrophic, eukaryotic

• multicellular prokaryote

• multicellular, autotroph, eukaryote
