QUESTION 5 Assuming mitosis is divided into prophase, prometaphase, metaphase, anaphase, and telophase, identify the events that take place in metaphase. The chromosomes move toward the equator by action of the kinetochore microtubules. The nucleolus disappears. Centrioles replicate. The nuclear envelope disappears. Microtubules attach to kinetochores. 000 All chromosomes are aligned on the metaphase plate. Sister chromatids split. Chromosomes condense. Spindle fibers form. Centrioles are migrating to opposite sides of the nucleus. QUESTION 6 Assuming mitosis is divided into prophase, prometaphase, metaphase, anaphase, and telophase, identify the events that take place in anaphase. Centrioles are migrating to opposite sides of the nucleus. Chromosomes decondense. The nuclear envelope reforms. The chromosomes move toward the equator by action of the kinetochore microtubules. All chromosomes are aligned on the metaphase plate. The nucleolus disappears. Sister chromatids split. Kinetochore microtubules shorten, pulling chromosomes to opposite poles. Spindle fibers form. Microtubules attach to kinetochores.

Question 4

Question 41 Which of the following statements does BEST compare the processes of mitosis and meiosis? O Mitosis involves two division cycles and results in haploid gametes, while meiosis consists of one division cycle and results in a diploid daughter cell O Mitosis involves two division cycles and results in diploid daughter cells, while meiosis consists of one division cycle and results in haploid gametes. O Mitosis involves one division cycle and results in diploid daughter cells, while meiosis consists of tavo division cycles and results in haploid gametes. O Mitosis involves one division cycle and results in haploid gametes, while meiosis consists of two division cycles and results in diploid daughter cells. Question 42 Why are glycolipids important in the cell membranes? O Glycolipid helps the cell to provide additional surface area. O Glycolipid helps the cell to regulate materials passing through the cell membrane. O Glycolipid helps the cell to store sugar molecules O…

What is the correct answer?

1. How did your results differ from the class data for each phase of mitosis? 2. Write a brief paragraph stating whether or not your hypothesis was supported by the class data that you collected and an explanation of why/why not.
