$$A = 6l^2$, V$$ = $$l^3$$

Question 4

Which of the following is NOT a characteristic commonly found in all types of connective tissue?

Accepted Answer

Cells specialized for contraction

Question 5

A histology slide shows tissue with densely packed collagen fibers and few cells. Which type of connective tissue is most likely present?

Accepted Answer

Dense regular connective tissue

Question 6

Which of the following best explains why stratified squamous epithelium is found lining the esophagus?

A biopsy reveals tissue with intercalated discs and branching fibers. Which tissue is this?

Accepted Answer

Cardiac muscle

Question 12

Which of the following is a key difference between endocrine and exocrine glands?

Accepted Answer

Adipose tissue

Question 14

Which of the following best describes the function of serous membranes?

Accepted Answer

Secreting lubricating fluid to reduce friction between organs

Question 15

Accepted Answer

Cutaneous membrane

Question 17

Which of the following best explains why simple columnar epithelium is found lining the small intestine?

Accepted Answer

It facilitates absorption and secretion due to increased surface area

Question 18
