Question

biology exam 4
for questions 1 - 6, use the diagram above.
(hint: the letters are for identification, but do not indicate the order of the process.)

1. what is the name and definition of the process shown in the diagram above?

a. mitosis; cell division resulting in four haploid daughter cells.
b. mitosis; cell division resulting in two diploid daughter cells.
c. meiosis; cell division resulting in four haploid daughter cells.
d. meiosis; cell division resulting in two diploid daughter cells.

1. what is the correct order of the stages in order from first to last?

a. a, c, d, b
b. c, a, d, b
c. b, c, a, d
d. d, c, a, b
for questions 3 - 6, identify the name for each of the following stages in the diagram above
(hint: stages a - d are not in the correct order. be sure to use the diagram and your answer to #2.)

1. stage a:______ a. prophase

b. telophase

1. stage b:______ c. metaphase
2. stage c:______ d. anaphase
3. stage d:______

for questions 7 - 10, identify what is happening in each of the stages in the diagram above.
(hint: stages a - d are not in the correct order. be sure to use the diagram and your answers to #2 and #3.)

1. stage a:______ a. chromosomes move to opposite ends of the cell and two nuclei are formed.
2. stage b:______ b. the spindle fibers help align the chromosomes along the cell equator.
3. stage c:______ c. dna condenses into tightly coiled chromosomes.
4. stage d:______ d. sister chromatids separate and move to opposite ends of the cell.

Explanation:

• Question 1: Mitosis results in two diploid daughter cells. Meiosis results in four haploid daughter cells.
• Question 2: The stages of mitosis in order are Prophase (chromosomes condense), Metaphase (chromosomes align at equator), Anaphase (sister chromatids separate), Telophase (nuclei reform).
• Question 3 - 6: Based on the characteristics of mitosis stages:
• Prophase: DNA condenses into chromosomes.
• Metaphase: Chromosomes align at cell equator.
• Anaphase: Sister chromatids separate.
• Telophase: Chromosomes at poles, nuclei form.
• Question 7 - 10: Matched with the stage - specific events.

Answer:

1. No correct option (assuming the process is mitosis, but the options have errors. If it's mitosis, the correct definition is cell division resulting in two diploid daughter cells. If it's meiosis, it should result in four haploid daughter cells. But the options don't have a completely correct pair).
2. C. B, C, A, D (assuming B is Prophase, C is Metaphase, A is Anaphase, D is Telophase)
3. d. Anaphase
4. a. Prophase
5. c. Metaphase
6. b. Telophase
7. d. Sister chromatids separate and move to opposite ends of the cell.
8. c. DNA condenses into tightly coiled chromosomes.
9. b. The spindle fibers help align the chromosomes along the cell equator.
10. a. Chromosomes move to opposite ends of the cell and two nuclei are formed.
