3 Name: COMP REVIEW SCIENCE 8 Comp Rev iew 1 Date: Homeroom: OBJECTIVES: By the end of review, students will be able to SWBAT obtain an 80% or higher on their Science Trimester 3 Comprehensive Exam. DO NOW Direction: Explain why the provided constructed responses are incorrect to the following questions. Then, provide a correct constructed response. 1. The diagram represents a simple animal cell. To the right of the cell, two cell structures have been enlarged and labeled A and B. A portion of structure B has been enlarged and labeled C. A description of each cell structure is provided in the chart below. Complete the chart by identifying each cell structure as DNA, chromosome, or chromatin. Answer: 0/3 Letter Description of Cell Structure Name of Cell Structure A Thread-like structure found in the nucleus that contains many units of hereditary information DNA B A single unit of hereditary information Chromosome Double-stranded molecule composed of genetic C material Chromatin Why is the response incorrect? It is incorrect because Provide a correct response. A correct response would be: 3

4 PRACTICE: CELLULAR BASICS (7 points) 1. List the three statements of the cell theory. Give an example from real life for each. (3 pt) 2. Define the word organelle and identify which controls all the cell s activities. (1 pt) 4

5 3. Identify the three main stages in the cell cycle. Describe the final product for each phase. (3 pts) PRACTICE: Genetic Replication (9 points) 4. Define asexual reproduction and describe the genetic material of the produced offspring. Identify at least advantage to asexual reproduction. (3 pt) 5

6 5. Define sexual reproduction and describe the genetic material of the produced offspring. Identify at least advantage to sexual reproduction. (3 pt) 6. Compare and contrast body cell and sex cells. Explain how sex cells are able to become body cells. (3 pt) 6

7 PRACTICE: Mendelian Heredity (9 points) 7. Spongebob s genotype is Ss for squarepants. State the Law of Segregation and how it relates to the genetic make-up of the plant s sex cells (2 pt) 8. Spongebob s genotype is Yy for yellow color. State the Law of Independent Assortment and how it affects the genotype of the plant s offspring. (2 pt) 7

8 9. Vocab Flashcards. (1pt each = 5 pt total) KEY TERM CONCEPT PICTURE ALLELE HETEROZYGOUS HOMOZYGOUS PHENOTYPE GENOTYPE 8

9 PRACTICE: Punnett Squares and Pedigrees (10 points) 10. The pedigree below shows the inheritance pattern of the recessive trait (h) that results in an unknown genetic condition. Based on the inheritance pattern, identify all the possible genotypes for each individual. Write their genotype on the pedigree. (3 pt) 11. If Ted and Joan decided to have another child, what is the probability that the child will have the condition? Use a Punnett square to justify your answer. (2 pt) 9

10 12. Explain why Ted and Joan s actual children do not exactly match the expected results of their Punnett square. ( 1pt) 13. A female who is heterozygous for dimples, has a baby with a man with dimples. No Dimples: D Dimples: d Complete a Punnett square for the parents to determine the possible genotypes and phenotypes of the baby. State the probability the child having dimples. (4 pt) 10

The allele combination Gg represents: A. Purebred, because it has two identical alleles for a trait. B. Dominant because it has a capital letter. C. Homozygous, because it has two identical alleles for a trait. D. Hybrid, because it has two different alleles for a trait. 14. A heterozygous, hybrid, dominant, tall pea plant would have what genotype? A. Tall B. TT C. Short D. Tt 15. A cross for green and yellow peas produces 25% yellow peas and 75% green peas. If this cross happens 100 times, how many offspring will have green peas? A. 0 B. 25 C. 50 D The Punnett square below shows a cross between two tall pea plants.
