Biology Warm-Ups SEMESTER 2 Biology 2012-2013 Ms. Chabot • Add the Florida Biology Standard to the top of the page. • Write out and answer the question. • Each Friday I will check your Composition Book for the Warm-Ups done during the week. Week 1: Review Standards Mitosis Standard 17-1 Students will describe the cell cycle and explain the process of MITOSIS in the formation of new cells. Standard 17-1 Sketch and Label the Cell Cycle Standard 17-2 Students will describe the purpose of mitosis. Mitosis occurs for: 1) 2) 3) Standard 17-2 Students will describe the purpose of mitosis. Mitosis occurs for: 1) Growth 2) Repair of damaged tissue 3) Production of new offspring in some organisms; ASEXUAL reproduction. Standard 17-3 Students will describe the relationship between the cell cycle and cancer. What controls how often cells perform mitosis? What occurs if this control is not regulated? Standard 17-3 Students will describe the relationship between the cell cycle and cancer. What controls how often cells perform mitosis? Chemicals called CYLCINS are responsible for the rate and timing of cell division. What occurs if this control is not regulated? When these chemicals are not properly controlled (too much or too little) cell division does not occur as programmed. Standard 17-4 Students will describe mutations that can lead to cancer development. What is a mutation? What are examples of mutagens? How do mutations affect cancer development? Standard 17-4 Students will describe mutations that can lead to cancer development. What is a mutation? Mutations are changes that occur in the genetics of an organism, resulting in some physical or chemical change. What are examples of mutagens (chemicals that causes mutations)? UV light, cigarette smoking, poor diet, pollution, alcohol. How do mutations affect cancer development? Mutations in the instructions for cell division can mess with the production or release of cell CYCLINS, resulting in bad mitosis. Students will describe the process of MEIOSIS. How are MITOSIS and MEIOSIS alike? How are they different? Standard 17-5 Students will describe the process of MEIOSIS. How are MITOSIS and MEIOSIS alike? • Both occur in phases • Both produce new cells. • Both occur in a variety of organisms. How are they different? • Mitosis occurs in 1 stage/Meiosis occurs in 2 stages. • Mitosis conserves the amount of DNA of the original cell/Meiosis reduces the amount of DNA to ½. Standard 17-5 Week 2: Standards Meiosis Students will describe the process of meiosis in the formation of HAPLOID cells. What do the following terms mean? • Haploid: • Diploid: Why is REDUCTION-DIVISION so important in the process of meiosis? Standard 18-1 Students will describe the process of meiosis in the formation of HAPLOID cells. What do the following terms mean? • Haploid: cell that contains HALF of the genetic info as another cell; usually a gamete; represented by N. • Diploid: cell that contains the double/full amount of genetic info for an organism; usually a somatic (body) cell; represented by 2N. Why is REDUCTION-DIVISION so important in the process of meiosis? Keeps the amount of genetic information for a specific species of organism CONSTANT. Standard 18-1 Students will describe the processes of INDEPENDENT ASSORTMENT and CROSSING OVER during meiosis. Describe the process of Independent Assortment. How does Crossing Over increase genetic diversity? Standard 18-2 Students will describe the processes of INDEPENDENT ASSORTMENT and CROSSING OVER during meiosis. Describe the process of Independent Assortment. As a cell undergoes MEIOSIS, chromosomes are separated into gametes to create a RANDOM ASSORTMENT of chromosomes within each gamete. How does Crossing Over increase genetic diversity? Swapping mother (maternal) and father (paternal) DNA guarantees each gamete will contain a UNIQUE combination from each parent’s parent. Standard 18-2 Students will describe the reasons inheritance outcomes are expresses as percent, ratios, and fractions. What is PROBABILITY? How does probability apply to genetics? Standard 18-3 Students will describe the reasons inheritance outcomes are expresses as percent, ratios, and fractions. What is PROBABILITY? The chance occurrence of a specific event or combination of events. How does probability apply to genetics? Reproduction with gametes is a chance occurrence; the chance that any 2 gametes will join during conception. Standard 18-3 Students will demonstrate the use of a PUNNETT SQUARE to predict the probability of genetic outcomes. A PUNNETT SQUARE is a tool used by scientists to predict the possible offspring when pairing a male and female organism for reproduction. The result is a PREDICTIVE PROBABILITY of the CHANCE, each time conception occurs, of producing offspring with specific characteristics.
