Biology EOC Mega-Review Packet Molecules to Organisms Define carbohydrate, lipid, protein, and nucleic acid. Describe the function of each. Explain how the structure of DNA allows it to store and transmit genetic information. (Released Test Question) Why do enzymes speed up chemical reactions? Describe how cell membranes maintain homeostasis through selective permeability. Cell Cycle and Cellular Processes Compare mitosis and meiosis. Why is meiosis important for sexual reproduction? (Released Test Question) What happens when nondisjunction occurs during meiosis? Define differentiation and explain how different cells perform different functions. Heredity and Genetics Use a Punnett square to predict offspring from two heterozygous parents. Which process produces the most genetic variation? (Released Test Question) Explain how environmental factors can affect gene expression. A DNA mutation occurs in a skin cell. What cells will contain the mutation? (Released Test Question) Evolution and Adaptation Define natural selection. Explain how antibiotic resistance develops in bacteria. (Released Test Question) Describe how genetic variation increases a population’s chance of survival. What evidence supports the theory of evolution? Ecosystems and Ecology Explain how energy flows through an ecosystem. Which model best represents energy transfer in a stable ecosystem? (Released Test Question) Describe the effects of a drought on a food web. Explain how human activities impact ecosystems. Explain why biodiversity is important for ecosystem stability. Questions Bio 1.1 3) Which macromolecule provides structural support and helps send signals within a cell? Bio 1.2 Bio 1.3 1) The diagram below is a plant cell with two parts labeled. . Bio.1.5 Bio 2.3 1) How does the process of photosynthesis in plants provide energy for animals? Bio.6.2 Two haploid cells with identical genetic information Two haploid cells with different genetic information Four haploid cells with identical genetic information Four haploid cells with different genetic information 2) According to Figure 2, how is DNA passed from parents to offspring? By the process of crossing over By the process of asexual reproduction By the process of sexual reproduction By the process of binary fission Use the diagram to answer question 2. The diagram below shows a process that affects chromosomes during meiosis. 2) What function is illustrated by the process shown above? How the process of crossing over leads to varied offspring How the process of crossing over leads to identical offspring How the process of crossing over leads to differentiation How the process of crossing over leads to fertilization Use the information below to answer question 5. The pedigree below shows a family with four children and the known blood types of individuals in the family. 5) What is the blood type of Person #2?
