Four of the dog's groups, not in order (real facts)
letter group of the dog A Carnivora B Eukarya C Mammalia D Animalia Esme puts four of the dog's groups in order, largest group first. Which order is correct?
- D, B, C, A
- B, C, D, A
- B, D, C, A
- A, C, D, B
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?
- Five: domain to order
- Four: domain to class
- Six: domain to family
- Three: domain to phylum
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?
- Eight: domain to species
- Six: domain to family
- Two: genus and species, where they differ
- Seven: domain to genus
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
- Five: class to species, where they differ
- Four: domain to class
- Three: domain to phylum
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?
- No organism here, because without a nucleus the three are Bacteria
- Haloarcula marismortui, because its wall has no peptidoglycan
- Escherichia coli, because it alone has a wall with peptidoglycan
- Deinococcus radiodurans, because it alone is a prokaryote
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 Bacteria, Escherichia coli in Eukarya
- Fern and pea in Eukarya, Escherichia coli in Bacteria
- Fern and pea in Eukarya, Escherichia coli in Archaea
A new cell card (model data)
feature what the cell has nucleus no peptidoglycan in the wall no lipid link in the membrane ether bond Pia reads a card for a new cell. Which domain fits it?
- Eukarya: its DNA is held inside a nucleus like other cells
- Archaea: no nucleus, no peptidoglycan, ether-linked lipids
- Bacteria: no nucleus, which is enough to place it in Bacteria
- Plantae: a cell like this belongs to the plant kingdom
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 must share a genus too
- 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
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?
- Plantae, a kingdom that holds both
- Chordata, the phylum above class
- Canidae, the family below 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?
- Animalia, the kingdom of the dog
- Plantae, the kingdom of the garden pea
- Mammalia, the class of the dog
- Eukarya, the domain that holds both
