- A. Simple squamous
- B. Simple columnar
- C. Simple cuboidal
- D. Stratified squamous
Answer: B. Simple columnar

What is the primary function of fibroblast cells in connective tissue?
- A. Secretion of fibers and matrix
- B. Destruction of pathogens
- C. Storage of fat
- D. Contraction of muscle
Answer: A. Secretion of fibers and matrix
Fibroblasts are specialized cells that produce and secrete fibers (collagen and elastin) and the ground substance of connective tissue.

Which tissue type is specialized for storage of fat in the body?
- A. Areolar tissue
- B. Adipose tissue
- C. Dense regular tissue
- D. Reticular tissue
Answer: B. Adipose tissue

If an organism has a body cavity that is not completely lined by mesoderm, it is termed as:
- A. Acoelomate
- B. Pseudocoelomate
- C. Eucoelomate
- D. Hemocoelomate
Answer: B. Pseudocoelomate
Pseudocoelomates possess a body cavity (pseudocoel) where the mesoderm is present as scattered pouches rather than a continuous lining.

A cell that lacks a nucleus and is biconcave in shape is specifically adapted for:
- A. Muscle contraction
- B. Efficient transport of oxygen
- C. Hormone secretion
- D. Nerve impulse transmission
Answer: B. Efficient transport of oxygen
Mature human erythrocytes (RBCs) lack a nucleus and are biconcave to increase surface area for efficient oxygen transport via hemoglobin.
