What is the total number of chambers in the stomach of domestic animals like cattle, buffalo, goat and sheep?
- A.Four
- B.Two
- C.One
- D.Three
Correct answer
Explanation
The correct answer is A, Four. Cattle, buffaloes, goats and sheep are ruminants, and a ruminant's stomach has four chambers.
The four chambers are the rumen, the reticulum, the omasum and the abomasum. Ruminants swallow grass quickly and store it in the rumen, where bacteria and protozoa break down cellulose. The partly digested food, called cud, is brought back to the mouth and chewed again at leisure, which is rumination. It then passes through the reticulum and the omasum, which absorbs water, to the abomasum, the true stomach, where gastric juice digests it as in humans.
B is wrong because two chambers is not the plan of any of these animals. C is wrong because a single-chambered stomach belongs to non-ruminants such as humans, horses and pigs. D is wrong because three chambers is the arrangement in camels, which are pseudo-ruminants, not in cattle or goats.
Exam tip: Rumen, reticulum, omasum, abomasum; the abomasum is the true stomach.

- A.Urea is produced in liver.
- B.Urea is produced in blood.
- C.Urea is produced from digestion of starch.
- D.Urea is produced in lung and kidney.
Show answer
Liver cells turn the toxic ammonia released from the breakdown of amino acids into urea through the ornithine cycle, also called the urea cycle.

- A.Condenser-Objective lens-Eyepiece-Body tube
- B.Objective lens-Condenser-Body tube-Eyepiece
- C.Condenser-Objective lens-Body tube-Eyepiece
- D.Eyepiece-Objective lens-Body tube-Mirror
Show answer
Light passes through the condenser to the specimen, is picked up by the objective lens, travels up the body tube and reaches the eye through the eyepiece.

- A.Haemoglobin present in RBC can carry only oxygen but not carbon dioxide.
- B.Haemoglobin of RBC can carry both oxygen and carbon dioxide.
- C.Haemoglobin of RBC can carry only carbon dioxide.
- D.Haemoglobin is only used for blood clotting and not for carrying gases.
Show answer
It binds oxygen at its iron-containing haem groups and carries some carbon dioxide on its protein chains. Each haemoglobin molecule has four polypeptide chains and four haem groups, and each haem iron can hold one oxygen molecule, forming oxyhaemoglobin in the lungs.

- A.Histones are proteins that are present in mitochondrial membrane.
- B.Histones are proteins that are present in nucleus in association with DNA.
- C.Histones are proteins associated with lipids in the cytosol.
- D.Histones are proteins associated with carbohydrates in the cytosol.
Show answer
They are the proteins around which DNA winds to form chromatin in the nucleus of eukaryotic cells. Histones are small basic proteins, rich in the positively charged amino acids lysine and arginine, which attract the negatively charged phosphate groups of DNA.
