Q: Which type of epithelial tissue is primarily found in the lining of the stomach and intestine?

Answer: B. Simple columnar — Simple columnar epithelium consists of tall, slender cells and is adapted for secretion and absorption in the gastrointestinal tract.

Q: What is the primary function of fibroblast cells in connective tissue?

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.

Q: Which tissue type is specialized for storage of fat in the body?

Answer: B. Adipose tissue — Adipose tissue is a modified areolar tissue that stores fat in specialized cells called adipocytes.

Q: If an organism has a body cavity that is not completely lined by mesoderm, it is termed as:

Answer: B. Pseudocoelomate — Pseudocoelomates possess a body cavity (pseudocoel) where the mesoderm is present as scattered pouches rather than a continuous lining.
