A researcher observes that certain epithelial cells have abundant microvilli on their apical surface. What is the most likely function of these cells?

Accepted Answer

Increasing absorption or secretion

Question 7

Which of the following best explains why stratified squamous epithelium is found in the skin?

Accepted Answer

Impaired attachment of epithelial cells

Question 9

Which of the following statements about connective tissue is correct?

Accepted Answer

It stores energy and supports other tissues

Question 10

A tissue sample is observed to have multiple layers of cells, with the outermost layer being flat and scale-like. Which type of epithelium is this?

Accepted Answer

Stratified squamous epithelium

Question 11

Which of the following best describes the function of tight junctions in epithelial tissue?

Accepted Answer

Preventing the passage of water and solutes between cells

Question 12

A patient with a rare genetic disorder cannot produce keratin. Which of the following consequences is most likely?

Accepted Answer

Increased water loss through the skin

Question 13

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

Accepted Answer

Simple epithelia are specialized for absorption and diffusion; stratified epithelia are specialized for protection

Question 14

Which of the following best explains why the endothelium of blood vessels is composed of simple squamous epithelium?
