Frank saw a wingless animal that was brown on its face and body with white on its belly. It also had a long furry tail with a black tip. Use the dichotomous key to determine which of the following animal Frank saw. (S7L1b)
a striped skunk
a little brown bat

Based on your knowledge about Domains and Kingdoms, which of the following pairs of organisms are most closely related? (S7L1a)
a dog and a horse
a lizard and a bacterium
a cat and an amoeba
a tree and a mushroom
Many people have the misconception that mushrooms belong to the Plant kingdom. To disprove this misconception, you conduct an experiment by growing plants and mushrooms under different amounts of light. The picture shows the data you obtained from your experiment. (S7L1b)
Based upon the data, which of the following is the best conclusion? (S7L1b)
Mushrooms belong to the Plant kingdom because they can grow in light.
Mushrooms belong to the Plant kingdom because they need water.
Mushrooms do NOT belong to the Plant kingdom because they can grow in the dark.
Mushrooms do NOT belong to the Plant kingdom because they need water.
On a recent research trip to the African rainforest, Donna discovered a new organism that is eukaryotic, multicellular, autotrophic, contains chlorophyll and reproduce through sexual reproduction. Which kingdom does the newly discovered organism most likely belong to? (S7L1b)
Animals
Plants
Bacteria
Fungi
Which of the following is a difference between bacteria and protists? (S7L1a)
Protists have cell walls, but bacteria do not.
Protists are prokaryotes, but bacteria are not.
Bacteria have nuclei, but protists do not.
Protists have membrane-bound organelles, but bacteria do not.
The branching diagram illustrates similarities and differences between various groups of organisms. Which two groups of organisms in the diagram are shown to be most closely related? (S7L1a)
Porifera and Echinodermata
Chordata and Platyhelminthes
Mollusca and Annelida
Arthropoda and Coelenterata
Some multicellular and single-celled organisms have been recently discovered around Lake Jackson, Georgia. Scientists observed that some of the organisms produce sexually, a few asexually and the organisms shared similar characteristics. For example, they all are eukaryotic but do not have specialized tissues and some have plant-like characteristic while other have animal-like characteristics. To what kingdom does the organism most likely belong? (S7L1a)
Kingdom Plantae
Kingdom Protista
Kingdom Fungi
Kingdom Animalia
Dil is studying two different type of birds: Polioptila caerulea and Guiraea caerulea. He was amazed by the similar characteristics both birds share. Based on the scientific names, Dil can conclude that the two types of birds (S7L1a)
belong to different genera
belong to different species
belong to different domains
belong to different kingdoms

Kingdom, Phylum, and Class
Order, Kingdom, Class
Genus, Species, Phylum
Based on the information in the table, which two organisms have the most shared characteristics? (S7L1a)
The Aardwolf and Gray Wolf have canine teeth, milk their young and are wolves.
The Lion and the Coyote share more than three characteristics.
The Gray Wolf and Coyote share more characteristics but of different species.
The Blue Whale and Lion belong to the same Kingdom, Phylum, and Class.
