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
- Five: domain to order
- Three: domain to phylum
- Four: domain to class
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?
- Four: domain to class
- Five: class to species, where they differ
- Three: domain to phylum
- Eight: domain to species
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 Archaea
- Fern and pea in Bacteria, Escherichia coli in Eukarya
- Fern and pea in Eukarya, Escherichia coli in Bacteria
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?
- 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
- Eukarya: its DNA is held inside a nucleus like other cells
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 an order too
- They share a class, so they share the phylum, kingdom and domain 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
- Chordata, the phylum above class
- Canis, the genus below class
- Plantae, a kingdom that holds both
“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
- Mammalia, the class of the dog
- Eukarya, the domain that holds both
- Plantae, the kingdom of the garden pea
