8. While playing basketball, Kevin was wounded in his left knee, so he washed the wound and went home. Three days later, he found that the wound had finally healed. In the healing process of Kevin's wound, what sort of cell division took place?
A. mitosis
B. meiosis
C. diakinesis
D. cytokinesis
9. In metaphase I of meiosis, how do homologous chromosomes contribute to greater variation in gametes?
A. Since homologous chromosomes dissociate during metaphase I from the spindle fibers, they transfer to the daughter cells at random.
B. During metaphase I, the homologous chromosomes are paired closely and undergo crossover as a lattice around them forms the synaptonemal complex.
C. In metaphase I, recombination of maternal and paternal chromosomes occurs because at their centromeres the homologous chromosomes are not connected.
D. At the metaphase plate, the random arrangement of homologous chromosomes guarantees the random destination of the chromosomes in the daughter cells.
10. Which of the following would you expect if an animal cell completed telophase?
A. individual chromatids separating
B. chromosomes clustered at the poles
C. formation of two genetically identical cells
D. formation of vesicles at the metaphase plate
