  1. 2nd Six Weeks Review

  2. Photosynthesis converts ____ energy into ______energy. Photosynthesis converts light energy into chemical energy.

  3. What is the high-energy molecule that stores energy from food? ATP

  4. What molecule is broken down through the process of cellular respiration to release energy? Glucose

  5. List the phases of mitosis in order. PMATC Prophase, Metaphase, Anaphase, telophase, cytokinesis

  6. Which phase of mitosis does formation of the nuclear membrane occur? Telophase

  7. Which phase of mitosis are the chromosomes moving away toward the pole of the cell? Anaphase

  8. What scientific instrument would you use to observe the stages of mitosis in a cell? microscope

  9. What is the significance of meiosis to a species? It creates genetic variation.

  10. How many chromosomes do human gametes contain? 23 (half the number of chromosomes from body cells)

  11. Do the daughter cells produced from mitosis have the same number or half the number of chromosomes as the parent cell? Same number (Mitosis makes two identical cells)

  12. If body cells of a dog have 72 chromosomes, how many chromosomes will the egg cells have? 36 chromosomes Meiosis makes four genetically different haploid cells. HALF THE NUMBER OF CHROMOSOMES.

  13. If the above cell is permeable only to water, what will happen to the cell when it is put into a beaker of distilled water? It will swell aka get bigger

  14. What would happen to a cell that was put into a 100% sugar solution? It will shrink.

  15. If 2 parents that were both dominant for the widow’s peak trait produced a child with no widow’s peak, what would the genotypes of the parents be? W w Ww x Ww W WW Ww ww w Ww

  16. In rabbits, black (B) is dominant to white (b). If a rabbit has a litter of 8, of which 4 are black and 4 are white. What would the genotypes of the parent rabbits be? B b Bb x bb b Bb bb bb b Bb

  17. In a monohybrid cross, if you cross two parents that are heterozygous for a trait, what is the expected phenotypic ratio? A a 3:1 A AA Aa aa a Aa

  18. In a dihybrid cross, what would be the expected phenotypic ratio if you crossed two heterozygous parents? 9:3:3:1

  19. In humans, "unattached" earlobes are dominant over "attached" earlobes. "Widows peak" hairline is dominant over "non-widows peak" hairline. Use E and e for the earlobe phenotype alleles, and W and w for the hairline phenotype alleles.A female and a male, both with genotype EeWw have a child with attached earlobes and widow’s peak hairline. What is the genotype of the child? eeWw or eeWW

  20. A female and a male, both with genotype EeWw have a child. What is the probability it will have attached earlobes and a widows peak hairline? A) 1/6B) 3/16 C) 1/16 D) 1/32 E) 3/32 B) 3/16 9:3:3:1

  21. In humans, "unattached" earlobes are dominant over "attached" earlobes. "Widows peak" hairline is dominant over "non-widows peak" hairline. Use E and e for the earlobe phenotype alleles, and W and w for the hairline phenotype alleles.A female with unattached earlobes and a widows peak hairline and a male with attached earlobes and a widows peak hairline have a child. The child has attached earlobes and a non-widows peak hairline. What are the genotypes of the parents? EeWw x eeww
