Ch 1 Review 1. Define Evolution?- organisms that adapt to the environment that they live in 2. Define Biology? – study of life 3. Define emergent properties and give an example. are created by new arrangements and interactions of parts as complexity increases. For example, photosynthesis can take place only when molecules are arranged in a specific way in an intact chloroplast. 4. How does a reductionist study science? Reductionism is the approach of reducing complex systems to simpler components that are more manageable to study. 5. What is systems biology? The ultimate goal of systems biology is to model the dynamic behavior of whole biological systems based on a study of the interactions among the system’s  parts. 6. What are the levels of biological organization? At the lowest level are atoms that are ordered into complex biological molecules. Biological molecules are organized into structures called organelles, the components of cells. Cells are the fundamental unit of structure and function of living things. 7. Define producers and consumers in an Ecosystem. The chemical energy in sugar is then  passed along by plants and other photosynthetic organisms (producers) to consumers.  Consumers are organisms, such as animals, that feed on producers and other consumers.  8. What is meant by structure suits it’s function? Form fits function; how a device works is correlated with its structure.Applied to biology, this theme is a guide to the anatomy of life at all its structural levels.For example, the thin, flat shape of a leaf maximizes the amount of sunlight that can be captured by its chloroplasts. 9. What is the lowest level of life? Cell 10. What is the difference between Eukaryotic and Prokaryotic cells? Eukaryotic mean nucleus- fungi, plants, protist,animial Prokaryotic means without nucleus- bacteria, Archaea 11. DNA is the genetic information. Explain. 12. What are the three domains of life? Bacteria, Archaea, and Eukarya 13. Name the six kingdoms that all organisms are classified in. Archaebacteria, eubacteria, Protista, fungi, plantae plants, animalia 14. What is the classification system of living organism according to Linnaeus? Categorized birds into three major groups. Linnaeus's system of classification was the first formal system of taxonomic organization. 15. How do scientists look at the dual nature of Unity and Diversity of Life? Life is diverse but unified. It is diverse by species by unified because of common ancestors. Evolution is what makes us come from common ancestors that is why our arm is similar to a bats wing. Also in diversity, the many species that arise from one common ancestor is a way of natural selection at work. Selecting its certain traits per each environment. This is how diversity occurs .

16. What is the two main points Darwin presented in Origin of Species? Darwin’s first point was that contemporary species arose from a succession of ancestors through “descent with modification.” Darwin’s second point was a proposed mechanism for descent with modification:

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
