BIOLOGY 1ST SEMESTER EXAM REVIEW NOTE: Please understand that I have done my best to put together a Study Guide for the exam. However, if there is something on the exam that is not on this study guide but it was covered this semester, then it has the possibility of being on the exam. You should not be using this as your only source of studying for the exam. It is my strong suggestion that you use your old tests to study for the exam as well as looking through each chapter thoroughly. Anything covered this semester could be on the exam. Chapters covered this semester: 1 – 4, 6 – 8, and 10 – 11 Chapter 1 Terms: biology reproduction development organism species stimulus response organization growth law adaptation homeostasis environment hypothesis theory experiment control group observations What are the characteristics of living things? Experiments: You will be given information and data about an experiment. You will have to identify the experimental group, the control group, the hypothesis, and draw conclusions based upon the data. Graphing Data: You will be given some data for which you will have to make a graph 1 graph: You will have to answer a few questions about a graph on population growth. These questions will deal with carrying capacity, the effect of altering various factors, the effect of introducing a new predator or prey. Also be able to identify a limiting factor as being density-dependent or density-independent. Be able to determine the independent and dependent variables and then answer some questions about the graph. Chapter 2 Terms: ecology biosphere abiotic factors biotic factors niche autotroph heterotroph decomposer omnivore herbivore carnivore scavenger food web food chain habitat Know the levels of organization of life. (page 40) Know the 3 types of symbiosis and be able to identify an example of each. (pages 44-45) Know the various levels of a food chain and be able to analyze a food chain. 1 food web: You will need to answer some multiple choice questions about this. Chapter 3, Section 1 Terms: limiting factors primary succession secondary succession climax community When do primary and secondary succession occur? Chapter 4 Terms: exponential growth J-shaped curve S-shaped curve prey carrying capacity competition predator immigration emigration demography What are the effects of crowding and stress? What is meant by density-dependent and density-independent factors? What are some examples of each? Chapter 6 Terms: molecule atom amino acids nucleic acids lipids starches carbohydrates proteins acids bases pH metabolism What are the 3 particles found in an atom, what is their charge, and location? What are the two types of bonding? Describe each. Be able to recognize each type. Be sure you know the differences b/w lipids, carbohydrates, nucleic acids, & proteins. What can be used to test for fats, simple sugars, and proteins. What are the pH values for acids, bases, & neutral substances? What does litmus do in each substance? Chapter 7 Be sure you know the following pats of the cell. What are the structure /function of each? These will be in the T/F, Multiple choice, etc. Cytoplasm DNA lysosomes nucleus Mitochondria vacuole chlorophyll ribosomes Golgo Apparatus cell wall plasma membrane endoplasmic reticulum Nucleolus cilia flagella Know the difference b/w multicellular & unicellular organisms Know the difference b/w prokaryotes & eukaryotes Be able to identify the parts of an animal cell and a plant cell on a diagram. Chapter 8 Terms: active transport passive transport hypotonic hypertonic isotonic plasmolysis selective permeability diffusion osmosis facilitated diffusion transport proteins fluid mosaic model mitosis centromeres centrioles chromosomes cell cycle spindle cancer What is the structure of the phospholipid bilayer? What are some causes of cancer? Be able to identify the phases of the cell cycle and what happens in each phase. What factors limit a cell’s size? Why? Osmosis and diffusion: You will be given a diagram showing an experiment dealing with hypertonic, isotonic, and hypotonic solutions. You will have to answer a few questions about this experiment. This is similar to the experiment you did in class with iodine and starch and selectively permeable membranes. Chapter 10 Terms: dominant recessive homozygous heterozygous alleles genetics genotype phenotype Gregor Mendel traits meiosis Be able to perform monohybrid and dihybrid crosses and give the genotype and phenotype ratios. Be able to identify the phases of meiosis and the characteristics of meiosis. Be able to compare it with mitosis. The cell cycle and meiosis: Be sure that you can recognize diagrams of the cell cycle and meiosis. Be sure you can compare & contrast the 2 processes. This will be in the form of a chart. Chapter 11 Terms: mutation frameshift mutation point mutation deletions insertions inversions translocations aneuploidy triploidy trisomy monosomy transcription translocation amino acids What is the structure of DNA? Be able to identify the different types of mutations by description or illustration. What are the 3 types of RNA? How are they similar? Different? Be able to transcribe & translate a segment of DNA to determine the amino acid sequence of the protein. You need to know how to use the chart on p. 292.
