1 Example Items iology iology Example Items are a representative set of items for the P. Teachers may use this set of items along with the test blueprint as guides to prepare students for the P. On the last page, the correct answer, content SE and SE justification are listed for each item. The specific part of an SE that an Example Item measures is NOT necessarily the only part of the SE that is assessed on the P. None of these Example Items will appear on the P. Teachers may provide feedback regarding Example Items. (1) ownload the Example Feedback Form and it. The form is located on the homepage of ssessment.dallasisd.org. OR (2) To submit directly, click Example Feedback after you login to the ssessment website. First Semester ode #: 3091

2 EXMPLE ITEMS iology, Sem 1 Use the diagram to answer the next question. 1 The process that is labeled with an is replication, which is the formation of new alleles translation, which is the process that converts mrn transcription, which is the process of copying a sequence of N to RN recombination, which ensures that each cell has one complete set of instructions Use the image to answer the next question. 2 In this photomicrograph of an onion root tip, what phase of mitosis is cell in? naphase Interphase Prophase Telophase allas IS - Example Items

3 EXMPLE ITEMS iology, Sem 1 3 On the hemoglobin gene, glutamic acid is sometimes replaced by valine. Source: ptbeach.com What is the significance of this change? point mutation causes sickle cell anemia, which results in disfigured red blood cells. chromosomal mutation causes Klinefelter s syndrome, which results in reduced fertility. translocation mutation causes chronic myeloid leukemia, which affects blood circulation. deletion mutation causes muscular dystrophy, which results in muscle degeneration and death. 4 To maintain homeostasis, cells absorb and excrete substances through the phospholipid bilayer of the cell membrane. In which process do cells use vesicles to excrete substances? Facilitated diffusion Endocytosis Exocytosis Simple diffusion allas IS - Example Items

4 EXMPLE ITEMS iology, Sem 1 5 Which statement is true about the process of photosynthesis? arbon dioxide is produced. Sugar is produced. TP is produced. Water is produced. 6 Which statement is incorrect? iffusion is a form of passive transport. Osmosis is a form of passive transport. ctive transport moves molecules from a lower to a higher concentration. Facilitated diffusion contains transport proteins that make transport across a membrane harder. Use the diagram to answer the next question. 7 omponents of N include a phosphate backbone and base pairs connected by a hydrogen bond carbon bond nitrogen bond phosphate bond allas IS - Example Items

5 EXMPLE ITEMS iology, Sem 1 8 Which biomolecule is correctly paired with its function? Lipids express genes Proteins form enzymes arbohydrates create hormones Nucleic acids insulate animal tissue Use the image to answer the next question. Source: my.hrw.com 9 n anticancer drug stops a cancer cell from dividing after the 2nd checkpoint. uring which stage is this drug most effective in the cell cycle? Gap 1 (G1) Synthesis (S) Gap 2 (G2) Mitosis (M) allas IS - Example Items

6 EXMPLE ITEMS iology, Sem 1 10 Which process is not a role of N? Expression of genes Mutation and recombination Encoding genetic information ontrolling environmental conditions 11 Some bacteria are able to digest milk because lactase helps to break down the sugar, lactose, in milk. Source: slideshare.net To code for the production of lactase in prokaryotes, the promoter and operator work as switches to activate or deactivate genes for lactase. This occurs during reproduction replication transcription translation allas IS - Example Items

7 EXMPLE ITEMS iology, Sem 1 Use the sequence to answer the next question. rossing Over in Meiosis Source: slideplayer.com 12 How is crossing over during meiosis significant? Genes from mother and father mix to increase the variety of traits expressed by their children. Gametes duplicate to alter the number of chromosomes present at the end of meiosis. Genes replicate in an exact fashion to ensure children have the same traits as the parents. Gametes begin with 48 chromosomes and still have 48 at the end of meiosis. Use the table to answer the next question. Organism 1 Organism 2 Organism 3 Organism 4 Reproduction Mitosis/Meiosis inary Fission Mitosis/Meiosis Sexual/sexual Nuclear membrane Level of organization Photosynthesis in a chloroplast Yes No Yes Yes Multicellular Unicellular Multicellular Most are unicellular Yes No No Yes 13 Which organism is prokaryotic? Organism 1 Organism 2 Organism 3 Organism 4 allas IS - Example Items

8 EXMPLE ITEMS iology, Sem 1 14 Two heterozygous tall (Tt) plants are crossed. What are the possible genotype combinations for the offspring? 100% TT 25% TT, 50% Tt, 25% tt 100% Tt 25% TT, 25% Tt, 50% tt allas IS - Example Items
