Dog and cat (real facts)
level dog cat domain Eukarya Eukarya kingdom Animalia Animalia phylum Chordata Chordata class Mammalia Mammalia order Carnivora Carnivora family Canidae a different family Jun counts the levels that a dog and a cat share. How many levels do they share?
- Six: domain to family
- Four: domain to class
- Three: domain to phylum
- Five: domain to order
Model plants P and Q (model data)
level P Q domain Eukarya Eukarya kingdom Plantae Plantae phylum Veldia Veldia class Orrin Orrin order Tamba Tamba family Dorix Dorix genus Pelor Mirel species rubra alba Kira counts the levels that two model plants share. How many of the eight levels do P and Q share?
- Seven: domain to genus
- Two: genus and species, where they differ
- Eight: domain to species
- Six: domain to family
Model animals R and S (model data)
level R S domain Eukarya Eukarya kingdom Animalia Animalia phylum Zorn Zorn class Plenk Brix order Kalo Sorn family Tavi Dree genus Mela Quill species nuri vera Luz counts the levels that two model animals share. How many of the eight levels do R and S share?
- Eight: domain to species
- Three: domain to phylum
- Five: class to species, where they differ
- Four: domain to class
Three prokaryotes (real facts)
organism nucleus peptidoglycan in the wall Escherichia coli no yes Deinococcus radiodurans no yes Haloarcula marismortui no no Milo sorts three prokaryotes into domains. Which organism is in a different domain from the other two?
- Deinococcus radiodurans, because it alone is a prokaryote
- Escherichia coli, because it alone has a wall with peptidoglycan
- Haloarcula marismortui, because its wall has no peptidoglycan
- No organism here, because without a nucleus the three are Bacteria
Three organisms (real facts)
organism what it is Escherichia coli a bacterium fern a plant garden pea a plant Noah sorts three organisms into domains. Which sorting is correct?
- Fern, pea and Escherichia coli in Eukarya, since each has a nucleus
- Fern and pea in Eukarya, Escherichia coli in Bacteria
- Fern and pea in Bacteria, Escherichia coli in Eukarya
- Fern and pea in Eukarya, Escherichia coli in Archaea
Model plants M and N (model data)
level M N domain Eukarya Eukarya kingdom Plantae Plantae phylum Veldia Veldia class Orrin Orrin order Tamba Kalo family Dorix Sorn genus Pelor Mirel species rubra alba Ren reads a card for two model plants. Which statement follows from the card?
- They share a class, so they share the phylum, kingdom and domain too
- They share a class, so they must share an order too
- They differ in order, so they cannot share a domain
- They share a class, so they must share a genus too
The dog's groups from largest to smallest (real facts)
step group of the dog 1 Eukarya 2 Animalia 3 Chordata 4 Mammalia 5 Carnivora 6 Canidae 7 Canis 8 lupus Tala knows that a dog and a cat share the class Mammalia. Which group must they also share?
- Canidae, the family below class
- Plantae, a kingdom that holds both
- Chordata, the phylum above class
- Canis, the genus below class
“Tree (real groups, not to scale):” Zee reads a nested tree. What is the smallest named group on it that holds both the dog and the garden pea?
- Eukarya, the domain that holds both
- Mammalia, the class of the dog
- Plantae, the kingdom of the garden pea
- Animalia, the kingdom of the dog
