Campbell's Biology, 9e (Reece et al.) Chapter 13 Meiosis and Sexual Life Cycles New questions are mostly at higher skill levels in this chapter. The new questions represent newer material both in the chapter and in the area of biological research. All questions with accompanying art work or questions grouped together as sets have been organized at the end of the chapter. Multiple-Choice Questions 1) If a horticulturist breeding gardenias succeeds in having a single plant with a particularly desirable set of traits, which of the following would be her most probable and efficient route to establishing a line of such plants? A) Backtrack through her previous experiments to obtain another plant with the same traits.

Campbell's Biology, 9e (Reece et al.) Chapter 12 The Cell Cycle In this chapter, 24 questions are new, and 12 have been altered to incorporate new material from the textbook. As in the other chapters, any questions that depend on figures or introductory scenarios have been placed at the end of the chapter rather than in concept sequence. Multiple-Choice Questions 1) The centromere is a region in which A) chromatids remain attached to one another until anaphase. B) metaphase chromosomes become aligned at the metaphase plate. C) chromosomes are grouped during telophase. D) the nucleus is located prior to mitosis. E) new spindle microtubules form at either end. Answer: A Topic: Concept 12.1 Skill: Knowledge/Comprehension

Chapter 4: Biodiversity and Evolution 4-1 What is biodiversity and why is it important? Biodiversity is a Crucial Part of the Earth?s Natural Capital Biological Diversity (Biodiversity) is the variety of the earth?s species. The genes they contain, the ecosystem in which they live, and the ecosystem processes such as energy flow nutrient cycling that sustain all life. Genetic Diversity enables life on earth to adapt and survive dramatic environmental changes. Ecosystem diversity are storehouses of genetic and species diversity Functional diversity is the variety of processes such as matter cycling and energy flow taking place within ecosystems. 4-2 Where Do Species Come From? Biological Evolution by Natural Selection Explains How Life Changes Over Time

Gurjit Singh Mitosis and meiosis Karen McLeary Produce an annotated word document or draw an annotated poster showing and explain the stages of mitosis and meiosis, explain how the behaviour of chromosomes leads to variation in cells. In mitosis the new cells being produce will be identically same to their parent cell. The DNA is exactly the same as the parent cell. There are five phases that it occurs in ? prophase, prometaphase, metaphase, anaphase and telophase. In prophase, the chromosomes become condensed, and discrete. The nucleoli disappear with each chromosome appears as two identical sister chromatids joined at the centromere.

Campbell's Biology, 9e (Reece et al.) Chapter 20 Biotechnology The new questions in Chapter 20 cover all of the chapter?s concepts and are primarily at the higher skill levels. In addition, the chapter presents several scenarios that are accompanied by a series of questions. Multiple-Choice Questions 1) Assume that you are trying to insert a gene into a plasmid. Someone gives you a preparation of genomic DNA that has been cut with restriction enzyme X. The gene you wish to insert has sites on both ends for cutting by restriction enzyme Y. You have a plasmid with a single site for Y, but not for X. Your strategy should be to A) insert the fragments cut with restriction enzyme X directly into the plasmid without cutting the plasmid.

Is the Ability to Write the Defining Aspect of Civilization? Toady five billion people can read and write. That is about eighty five percent of the world?s population. If it was not for the creation of writing by the early people we would still be living like them. Sumerians, Egyptians, Greeks, Romans, and the Chinese people all invented some type of unique writing form. Writing is a defining part in many civilizations histories.

39.2 Plant hormones 131095 SunHa Lee cytokinins - 2) apical dominance Apical dominance: ability of the apical bud to suppress the development of axillary buds Direct inhibition hypothesis: auxin & cytokinins act antagonistically in regulating axillary bud growth - auxin: sent from apical bud, directly inhibits axillary growth - cytokinins: sent from roots, signals axillary growth Ratio of auxin and cytokinins is important 2) apical dominance Apical bud removed: no inhibition of axillary buds, more lateral branches Auxin added: lateral bud growth repressed Overload of cytokinins: more lateral branches, bushier 3) anti-aging effects Slow aging - inhibit protein breakdown - stimulate RNA and protein synthesis - mobilize nutrients from nearby tissues

Chapter 43 TheImmuneSystem 43-3,4 Active/Passive Immunization Active immunity : defenses that arise when a pathogen infects the body and prompts a primary or secondary immune response Passive immunity : antibodies guard against pathogens that have never infected them (lasts as long as antibodies last) ? Example: mother?s IgG & IgA antibodies to baby Artificial active immunity: immunization (vaccination) Antigens used to make vaccines Artificial passive immunity: inject antibodies from an animal already immune into another animal ? Short-term but immediate Polyclonal/Monoclonal Antibodies : Polyclonal or monoclonal Polyclonal : products of many different clones of plasma cells Monoclonal : made from a single clone of B cells grown in culture
