Question 1

Which phase of mitosis is characterized by the alignment of chromosomes along the metaphase plate, preparing them for separation?

Accepted Answer

Metaphase

Question 2

The tissue shown in the second image is most likely which type of epithelial tissue, based on its multiple layers and flattened surface cells?

Accepted Answer

Stratified squamous epithelium

Question 3

During which stage of mitosis do sister chromatids separate and move toward opposite poles of the cell?

Accepted Answer

Anaphase

Question 4

Which of the following best describes the function of stratified squamous epithelium in the human body?

Accepted Answer

Protection against abrasion

Question 5

If a cell has 46 chromosomes before mitosis, how many chromosomes will each daughter cell have after mitosis?

Accepted Answer

46

Question 6

Which equation correctly represents the number of chromosomes in daughter cells after mitosis, given $$n$$ chromosomes in the parent cell?

Accepted Answer

$$n$$

Question 7

A patient has a genetic mutation that disrupts spindle fiber formation during mitosis. Which phase would be most directly affected?

Accepted Answer

Prophase

Question 8

Which of the following is NOT a characteristic of epithelial tissue?

Accepted Answer

Contains abundant extracellular matrix

Question 9

In a histology lab, a student observes a tissue sample with multiple layers of cells, where only the bottom layer touches the basement membrane. What type of tissue is this?

Accepted Answer

Stratified squamous epithelium

Question 10

Which process immediately follows telophase in the cell cycle?

Accepted Answer

Cytokinesis

Question 11

A researcher stains a tissue and observes flattened cells at the surface and cuboidal cells at the base. What is the most likely function of this tissue?

Accepted Answer

Protection

Question 12

Which of the following best explains why stratified squamous epithelium is found in areas subject to friction, such as the skin and esophagus?

Accepted Answer

It provides a thick, protective barrier

Question 13

During mitosis, which structure is responsible for moving chromosomes to opposite poles?

Accepted Answer

Spindle fibers

Question 14

If a tissue sample shows cells undergoing mitosis at a high rate, what can be inferred about the tissue's function?

Accepted Answer

It is likely involved in protection and renewal

Question 15

Which of the following equations represents the total number of cells produced after $$k$$ rounds of mitosis, starting from a single cell?

Accepted Answer

$$2^k$$

Question 16

A biopsy of the esophagus reveals many layers of cells with flattened surface cells. Which histological feature is most important for its function?

Accepted Answer

Multiple cell layers for abrasion resistance

Question 17

Which phase of mitosis is marked by the reformation of the nuclear envelope and the decondensation of chromosomes?

Accepted Answer

Telophase

Question 18

A tissue sample from the skin shows cells at the base actively dividing, while surface cells are dead and flattened. What process is responsible for this renewal?

Accepted Answer

Mitosis

Question 19

Which of the following is a key difference between simple and stratified epithelial tissues?

Accepted Answer

Stratified epithelia have multiple layers; simple have one

Question 20

A patient with a genetic disorder affecting mitosis is likely to have problems with which of the following processes?

Accepted Answer

Tissue repair and growth
