Question

a teacher showed slides of different stages of mitosis to four students and asked them to describe the stage viewed under the microscope. which student correctly described the stage? student 4 student 2 student 1 student 3

Explanation:

Step1: Analyze Student 1

Chromosomes assembling at the equator is metaphase. But the diagram for Student 1 shows chromosomes being pulled apart (anaphase - like movement), so Student 1 is incorrect.

Step2: Analyze Student 2

Nuclear membrane starting to reappear is telophase. The diagram for Student 2 shows early - stage mitosis (chromosomes condensing, not telophase), so Student 2 is incorrect.

Step3: Analyze Student 3

Chromosomes moving away from the poles is incorrect description. Chromosomes move towards the poles in anaphase. The diagram for Student 3 shows chromosomes at the equator (metaphase - like), so Student 3 is incorrect.

Step4: Analyze Student 4

Cytoplasm divides to form two daughter cells is cytokinesis (end of mitosis). The diagram for Student 4 shows two cells being formed (cytokinesis), so Student 4 is correct.

Answer:

Student 4
