- You are examining an organism you believe to be an animal. Which of the following would NOT support your hypothesis? O A The organism appears to be heterotrophic. O B The organism appears to be multicellular. O C The organism appears to be motile. O D The organism appears to have cell walls. O E All animals, including sponges, have development directed by Hox genes.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.1. Serial endosymbiosis is the most supported theory on how the first eukaryotic cells evolved from prokaryotic cells. The figure depicts the evolution of eukaryotic cells which include links to prokaryotic cells from early in the history of life. Identify the cellular structures involved in the connection of eukaryotic and prokaryotic cells. Describe the characteristics of the cellular structures that supports the evolutionary connection. а.
- 1. Design a cell/a system of cells using the following to show explicitly. Respiratory system, Energy generation, Forming tissue, and Maintaining order. 2. Sketch and/or design cellular systems to identify the basic features of life. Please show each feature using arrows to point that out in the drawing. 3. Give details on how your body structure resembles with your grandfather. Please use the understanding from DNA and/or RNA structure. 4. From your understanding sketch and explain how the evolution affected Dodo and completely got them towards extinction.1. Distinguish the features of the different kingdoms of life and their respective taxonomic groups according to functional organization, maintenance and integration functions, reproduction, development and ecology. Discuss it thoroughly and do not just copy from somewhere, please.A. Classify the organisms (A-D) based on their oxygen requirements. Name one location where you are most likely to encounter these organisms (1 location/organism).B. Organism C could not grow in the presence of oxygen. Explain the molecular reason behind this observation (What affect did oxygen have on C that caused it not grow)? C. Your friend repeats the above experiment in Question1 and observes growth of all 4 organisms on both plates. Provide an explanation for her results. (You may assume that your results are correct, since you have repeated the experiment several times and gotten the same results).
- 1.List down some fundamental characteristics that are common to ALL cells and fundamental functions that are common to ALL cells. 2.Provide five key comparisons between the structure of prokaryotic and eukaryotic cells. 3.Compare/contrast the following mechanisms of prokaryotic and eukaryotic cells in terms of: •Reproduction •Locomotion •Metabolism1) Name and give a brief account of the theory that explains the evolution of Eukaryotic cells from Prokaryotic cells. 2) Explain the reactions that occur to form polysaccharides, using starch as an example. 3) What do enzymes do? What are their main structural features? Give an example of a biological enzyme. 4) Describe the structure of fats and lipids. Why are some solid at room temperature whereas others, particularly from plants, are liquid? Briefly describe the structure of an animal cell. What are the main differences between animal and plant cells? Briefly outline the steps involved in the synthesis of ATP in eukaryotic cells• Organisms A, B, and C are all in the same family. • Organisms B and C are in the same genus. Given that information, select all the true statements about the relationships among these organisms. organism B is more related to C than to A organisms A, B, and C are in the same domain organism C is more related to A than to organisms A, B, and C are in the same species organisms A, B, and C are in the same phylum organisms A, B, and C are in the same order
- 1.. How are organisms alike and different? 2. How do different organisms meet their needs for survival? 3. How can we use the observable properties of organisms to group them1. Describe the diversity in organisms and the unifying concepts that integrate them. Discuss it thoroughly and do not just copy from somewhere, please.Select two items that biologists agree are necessary in order to consider an organism “alive.” For each, give an example of a nonliving object that otherwise fits the definition of “alive.”
