Describe 2 conclusions that can be made from this information.

10 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 levels of classification that the mushroom sea squirt, Sycozoa gaimardi, shares with four other organisms. 12. To which of the four organisms is the mushroom sea squirt most closely related?

11 13. Which of the beetles above must belong to the same family?

12 14. 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 below summarizes the students’ answers. Based on the classifications, which student gave the correct answer to the question? StudentWhales Most Closely Related Reason 1killer whale and gray whale They are both mammals. 2humpback whale and pygmy right whale They are both whales. 3fin whale and minke whale They are both in the same genus. 4North Atlantic right whale and bowhead whale They are both in the same family.

14 17.The Ursidae family of animals includes the giant panda, the brown bear, the polar bear, and the spectacled bear. Which of the following characteristics best helps classify these bears into genus and species levels? A.eating habits B.gene sequences C.method of reproduction D.location of natural habitat
