Show Answer
Answer: Connect bones to bones
Explanation: Ligaments connect bones to each other and provide joint stability.
Q12. Which epithelium is responsible for absorption in the intestine?
Columnar epithelium with microvilli
Cuboidal epithelium
Squamous epithelium
Ciliated epithelium
Show Answer
Answer: Columnar epithelium with microvilli
Explanation: Columnar epithelium with microvilli increases surface area for absorption in intestines.
Q13. Which type of connective tissue contains fat-storing cells?
Adipose tissue
Areolar tissue
Cartilage
Bone
Show Answer
Answer: Adipose tissue
Explanation: Adipose tissue stores fat and acts as insulation and cushioning for organs.
Q14. Which cells in cockroaches are associated with excretion?
Uricose glands
Malpighian tubules
Nephridia
Hepatocytes
Show Answer
Answer: Malpighian tubules
Explanation: Malpighian tubules are excretory organs in cockroaches responsible for removing nitrogenous waste.
Q15. The nerve cord of an earthworm is located:
Ventrally
Dorsally
Laterally
Obliquely
Show Answer
Answer: Ventrally
Explanation: In earthworms, the nerve cord runs along the ventral side of the body.
Q16. The excretory organs in earthworms are:
Nephridia
Kidneys
Malpighian tubules
Ureters
Show Answer
Answer: Nephridia
Explanation: Nephridia are segmentally arranged tubular structures that help in osmoregulation and excretion.
Q17. Which animal shows segmentation in its body structure?
Earthworm
Frog
Cockroach
Hydra
Show Answer
Answer: Earthworm
Explanation: Earthworms have a segmented body divided into repeated units called metameres.
Q18. What distinguishes pseudostratified epithelium from stratified epithelium?
All cells touch the basement membrane
Multiple layers of cells
Keratinization
Presence of cilia
Show Answer
Answer: All cells touch the basement membrane
Explanation: In pseudostratified epithelium, all cells contact the basement membrane despite appearing multilayered.
