- Based on their anatomical and behavioral differences, biologists previously placed humans and chimpanzees in different families, but now DNA sequence data suggest that they are closely related and should be placed in the same family. What are some advantages of using DNA sequences to decide how to classify organisms? What might be some disadvantages?BIO 106 – Reading – Unit 1 Name Topic 1: Introduction to Human Life Science – Biology – Section 1.1 What are the characteristics of life? 1. 2. 3. 4. 5. 6. 7. Metabolism – Homeostasis – Section 1.2 How are living organisms grouped? What are the three domains of life? What are the four kingdoms in Eukarya? Classification of humans: Kingdom: Phylum: pg. 11. 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.
- Why do many people, even biologists, find it difficult to define life?WRITE ABOUT A THEME: Organization You have seenmany examples of how form fits function at all levels of thebiological hierarchy. However, we can imagine forms thatwould function better than some forms actually found innature. For example, if the wings of a bird were not formedfrom its forelimbs, such a hypothetical bird could fly yet alsohold objects with its forelimbs. In a short essay (100–150words), use the concept of “evolution as tinkering” to explainwhy there are limits to the functionality of forms in nature.Which of the following is not a characteristic of a dichoto-mous key?(a) The dichotomous key has a “quartet” of statements de-scribing the characteristics of organisms.(b) Each statement is followed by directions to go to an-other pair of statements until the name of the organismis identified.(c) It is the most common type of key used by biologists toidentify organisms based on their characteristics.(d) Paired statements present an “either-or” choice so thatonly one statement is true.(e) a and b.
- 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.1. We have sent two objects into distinct space with information meant to be found by an extraterrestrial intelligence, the Pioneer Plaque and the Voyager Golden Record. Pick one of these objects and describe three things included. 2. In class we discussed the emergence of intelligent life on Earth. Why might or might not this be considered an evolutionary advantage? 3. In biological terms, what is the definition of a species?You have seen many examples of how form fits function at all levels of the biological hierarchy.
