Plantae, Fungi, Protista, Animalia
Animalia, Protista, Plantae, Fungi
Plantae, Protista, Fungi, Animalia
Fungi, Plantae, Protista, Animalia
During a research project, a scientist collects snails from a beach. He finds several snails that have shells of about the same size and shape. However, the shells have very different patterns and colors. How could the scientist best decide whether the snails belong to different species or to the same species?
He could study how the snails develop
He could examine the snails' RNA and DNA
He could classify the snails according to shell color.
He could look for other physical similarities in the snails.
Some living things are able to tolerate life in hot springs. To which of the following domains would these organisms most likely belong?
Archaea
Protista
Eukarya
Bacteria
As Carolus Linnaeus was growing up, he was interested in botany and in the names of plants. His ideas have influenced generations of biologists. How did Carolus Linnaeus contribute to modern classification systems?
He identified the three domains of life.
He developed two-part scientific names.
He standardized common names of organisms.
He used chemical characteristics to classify organisms.
The pictures show four types of organisms. Which of these would you most expect to be true if these organisms were classified by their physical characteristics only.
organisms 1 and 3 would be in the same species
organisms 2 and 4 would be in the same genus
organisms 1 and 3 would be more closely related than organisms 2 and 4
organisms 2 and 4 would be more closely related than organisms 1 and 3
Kayla listed several important questions that scientists try to answer when they classify organisms. Her list included the following questions: How many living things are there? What are the characteristics that define living things? What additional question would be best for Kayla to add to her list about classification.
How are living things related?
How do living things get energy?
What do living things need to survive?
Where do living things make their home?
Taxonomy is the science of describing, classifying, and naming living things. Which classification includes all protists, fungi, plants, and animals?
Phylum Chordata
Class Mammalia
Domain Eukarya
Order Carnivora
The three domains, Bacteria, Archaea, and Eukarya, represent very different forms of life. Domain Bacteria is made up of prokaryotes. Domain Eukarya is made up of eukaryotes. Which of the following statements correctly describes forms of life found in Domain Eukarya?
The organisms are single or mulitcellular and have complex cell structures.
These one-celled organisms live in harsh environments, such as the deep ocean and hot springs.
The organisms have cell walls, reproduce by cell division, and live and on the human body.
These unicellular organisms lack a nucleus in their cells and are found in almost any environment.
Which kingdom of Domain Eukarya identifies life forms such as algae and slime molds?
Kingdom Plantae
Kingdom Fungi
Kingdom Animalia
Kingdom Protista
Among its many characteristics, which of the following is unique to organisms found in the Kingdom Plantae?
are multicellular
lack chloroplast
have cell walls
are heterotrophs
