Chapter 11, Problem 12SQ

Scientists discover a new characteristic in some organisms in Kingdom X. They decide this characteristic is important enough to place these organisms in a new kingdom: Kingdom Y. Which sentence accurately describes the other levels of organization in this new kingdom? O The phyla would be new, but the classes, orders, and families would not be new. O The phyla and classes would be new, but the orders and families would not be new. O The phyla, classes, orders, and families would all be new. O The phyla, classes, orders, and families would not be new.

You have now studied three different types of anatomical structures. Homologous structures show individual variations on a common anatomical theme. These are seen in organisms that are closely related. 1. Give an example of a homologous structure from this activity: Analogous structures have very different anatomies but similar functions. These are seen in organismsthat are not necessarily closely related but live in similar environments and have similar adaptations. 2. Give an example of an analogous structure from this activity: Vestigial structures are anatomical remnants that were important in the organism's ancestors but are nolonger used in the same way. 3. Give an example of a vestigial structure from this activity:

b. the fossil record d. Čell theory 18. Which of these evolves? C. genes d. all of these a. individuals b. populations minate Education TM, Inc.

Figure 1.8 Which of the following statements is false? A. Tissues exist within organs which exist within organ systems. B. Communities exist within populations which exist within ecosystems. C. Organelles exist within cells which exist within tissues. D. Communities exist within ecosystems which exist in the biosphere.

You are photojournalist in a science magazine. For its next issue, you have been assigned to feature the difference between 3- Domain Scheme from 5-Kingdom Scheme of classification of living things. Using your knowledge and concept of taxonomy. a. the 3-domain scheme, description of each and sample organisms;b. the 5-kingdom scheme, description of each and sample organisms; andc. includes the technologies used as basis in the shifting of the classification from the kingdom scheme to domain scheme.

Which of the following is not a characteristic of all living organisms? Group of answer choices A. Have a brain B. Has systems of related parts C. Reproduces D. Grow and develops

17) Multicellularity is an important evolutionary innovation in the history of life on Earth. For the following statements, designate which is true (T) and which is false (F). Correct the false.    Multicellularity has evolved independently a few times in the history of life.   Multicellular members of domain Eukarya arose through the process of endosymbiosis.   Multicellular organisms have cells specialized for different functions, with each cell     type having a unique genetic sequence.   Cell differentiation occurs in unicellular organisms but not in multicellular organisms.   Multicellular organisms are absent from the domain Archaea.

The most inclusive level of classification isa. species.b. kingdom.c. domain.d. phylum.

A unicellular organism has a cell wall, a nucleus, chloroplasts, and several flagella. Which classification best matches this organism? O A. prokaryotic eubacteria O B. eukaryotic protist C. prokaryotic archaebacteria O D. eukaryotic plant
