BELL WORK: Copy and answer the question below: Why is a standardized taxonomic system helpful to scientists? Turn in your shark and/or alien dichotomous keys from yesterday!!

Set up the next page in your journal… Page: 54 Date: Title: Taxonomy Review NOT Cornell notes!

Taxonomy Recap… MORE INCLUSIVE (INCLUDES MORE STUFF) MORE EXCLUSIVE (INCLUDES LESS)

Taxonomy Recap… ORGANISMS BECOME LESS RELATED ORAGNISMS MORE CLOSELY RELATED

Taxonomy Recap… If an organism is in one Taxon, then it is automatically included in any taxa above it! But not necessarily included in the taxa below it

For today… You will do a walking review. There are TWO copies – set #1 is spread out along the back wall; set #2 is condensed on the side cabinets. They are all the same questions. You have 20 minutes to answer all 20 questions – work quickly!

Explain TWO things you can tell about the relationships between these organisms. buffalo & gazelle are most closely related; all share 3 taxa; zebra is less closely related to the other two

The mushroom sea squirt is in the same class as the common sea grape. The mushroom sea squirt is in the same family as the blue spot ascidian. The mushroom sea squirt is in the same order as the white speck tunicate. The mushroom sea squirt is in the same phylum as the starry skate. The information below describes the most specific taxa that the mushroom sea squirt, Sycozoa gaimardi, shares with four other organisms. 13. To which of the four organisms is the mushroom sea squirt most closely related? Explain your answer blue spot ascidian – family is most specific

14. Which of the beetles pictured must belong to the same family? Explain your answer. same genus means everything above is also the same

15. Four students researched the classifications of the following eight whales: killer whale, Orcinus orca gray whale, Eschrichtius robustus humpback whale, Megaptera novaeangliae pygmy right whale, Caperea marginata fin whale, Balaenoptera physalus minke whale, Balaenoptera acutorostrata North Atlantic right whale, Eubalaena glacialis bowhead whale, Balaena mysticetus The students were asked which two whales are most closely related and why. The table here summarizes the students’ answers. Which student gave the correct answer to the question? Student Whales Most Closely Related Reason 1 killer whale and gray whale They are both mammals. 2 humpback whale and pygmy right whale They are both whales. 3 fin whale and minke whale They are both in the same genus. 4 North Atlantic right whale and bowhead whale They are both in the same family.

16. Identify the organism pictured below

17. Which of the following is NOT a reason why a standardized taxonomic system is important to the scientific community? a.It allows scientists to classify organisms using a universal naming system. b.It allows scientists to study the evolutionary history of organisms based on their classifications. c.It allows scientists in different parts of the world to use their own naming system. d.It helps scientists avoid ambiguity by using a universal naming system.

Scientists compared the DNA sequence of a gene in four mammals. A portion of the gene’s DNA sequence in each mammal is shown below:. 18.
