Q. No.Erythroblastosis foetalis occurs when an Rh-negative mother carries an Rh-positive foetus. What happens if this condition is left untreated in a subsequent pregnancy?
1.
The foetus may suffer from severe anaemia and jaundice due to maternal Rh antibodies attacking fetal RBCs.
2.
The mother’s immune system remains unresponsive to Rh-positive RBCs in subsequent pregnancies.
3.
The foetus develops an overproduction of RBCs to counteract maternal antibodies.
4.
The condition only affects the first pregnancy, with no impact on later pregnancies.

Identify the incorrect statement:
| 1. | Neutrophils are the most abundant cells (60-65 per cent) of the total WBCs and basophils are the least (0.5-1 per cent) among them. |
| 2. | Neutrophils and monocytes (6-8 per cent) are phagocytic cells which destroy foreign organisms entering the body. |
| 3. | Basophils secrete histamine, serotonin, heparin, etc., and are involved in inflammatory reactions. |
| 4. | Lymphocytes (2-3 per cent) resist infections and are also associated with allergic reactions. |

What is the function of thrombokinase in blood clotting?
| 1. | Thrombokinase directly converts fibrinogen into fibrin, which forms a clot. |
| 2. | Thrombokinase is an enzyme complex that converts prothrombin into thrombin, which subsequently converts fibrinogen into fibrin. |
| 3. | Thrombokinase prevents clot formation by inhibiting thrombin activity. |
| 4. | Thrombokinase dissolves clots by breaking down fibrin into smaller fragments. |

Why do higher animals like mammals and birds possess a closed circulatory system instead of an open one?
| 1. | Because it allows blood to come in direct contact with tissues for faster absorption of oxygen |
| 2. | Because closed circulation prevents blood from reaching vital organs |
| 3. | Because open circulation is too complex for warm-blooded animals |
| 4. | Because a closed system permits more efficient nutrient and gas exchange through capillaries under controlled pressure |
