4.
Which one of the following pairs of the kind of cells and their secretion is correctly matched

Oxyntic cells a secretion with pH between 2.0 and 3.0

Alpha cells of islets of Langerhans secretion that decreases blood sugar level

Kupffer cells a digestive enzyme that hydrolyses nucleic acids

Sebaceous glands a secretion that evaporates for cooling

Sebaceous glands

a secretion that evaporates for cooling

Oxyntic (or parietal) cell is present in the wall of the stomach that produce HCI which forms the part of gastric juice. Oxyntic cell also produce intrinsic factor which is involved in the absorption of vitamin B₁₂ in the small intestine. The pH of gastric acid is 2-3 in the stomach of the lumen. The acidity being maintained by the proton pump, a H⁺/ K⁺ ATPase.

Alpha cell ofislets of langerhans secrete glucagon hormone which raises blood glucose level by stimulating liver to convert glycogen to glucose and by stimulating the conservation of fatty acids and amino acids to glucose.

Kupffer cells arc specialized macrophages that disposes of old blood cells and particulate matter. Kupffer cells, named after Karl Wilhem Von Kupffer, are found in the bloodstreams and in the liver, attached to the walls of the sinusoids.

Sebaceous gland is a simple or branched glands in the skin that secrete an oily substance, sebum which is fatty mildly antiseptic material that protects, lubricates, and waterproofs the skin and hair and help prevent dessication.

Examine the diagram of the two cell types A and B given below and select the correct option

A B

Cell A is the rod cell found evenly all over retina
Cell A is the cone cell more concentrated in the fovea central is
Cell B is concerned with colour vision in bright light
Cell A is sensitive to low light intensities

A cricket player is fast chasing a ball in the field. Which one of the following groups of bones are directly contributing in this movement

Femur, malleus, tibia, metatarsals
Pelvis, ulna, patella, tarsals
Sternum, femur, tibia, fibula

Hemidactylus showing sexual dimorphism
Varamus showing mimicry
garden lizard (Calotes) showing camouflage
Chamaeleon showing protective colouration
