Question 3

Which equation correctly represents the relationship between the number of cell layers ($$n) in a $$stratified epithelium and the total thickness ($$T) if $$each layer has an average thickness $$t$$?

Accepted Answer

$$T = n 	imes t$$

Question 4

Accepted Answer

Organization

Question 5

Which connective tissue type is most likely to be found in tendons, and what is its main structural protein?

Accepted Answer

Dense regular connective tissue; collagen

Question 6

Which of the following best explains why stratified squamous epithelium is found on the external part of the skin?

Accepted Answer

It provides protection against abrasion and pathogens.

Question 7

A multicellular exocrine gland with a branched duct and secretory units shaped like sacs is classified as:

Accepted Answer

Compound alveolar gland

Question 8

Which equation best represents the rate of diffusion ($$R) $$across a simple squamous epithelium, given surface area $$A$$, concentration difference $$\Delta C$$, and membrane thickness $$d$$? (Assume $$k is a $$constant)

Accepted Answer

$$R = k \frac{A \Delta C}{d}$$

Question 9

Which of the following is a characteristic unique to cardiac muscle tissue?

Accepted Answer

Connective tissue

Question 15

Which of the following best describes the process of regeneration in tissue repair?

Accepted Answer

Original tissue is replaced by the same type of cells, restoring normal function.

Question 16

Which membrane lines body cavities that are open to the exterior and is composed of an epithelial layer over connective tissue?

Accepted Answer

Mucous membrane

Question 17

Which of the following is a function of adipose tissue?

Accepted Answer

Storing energy and insulating the body

Question 18

Which equation best represents the total volume ($$V) of $$ground substance in connective tissue, given the concentration ($$c) $$and total tissue mass ($$m$$)?

Accepted Answer

$$V = c 	imes m$$
