Q. No.Colostrum, the yellowish fluid, secreted by the mother during the initial days of lactation is very essential to impart immunity to newborn infants because it contains:
| 1. | Immunoglobulin A | 2. | Natural killer cells |
| 3. | Monocytes | 4. | Macrophages |
Short-lived immunity acquired from mother to foetus across the placenta or through mother's milk to the infant is categorised as:
| 1. | Active immunity | 2. | Passive immunity |
| 3. | Cellular immunity | 4. | Innate non-specific immunity |
The yellowish fluid "colostrum" secreted by mammary glands of the mother during the initial days of lactation has abundant antibodies (IgA) to protect the infant. This type of immunity is called as:
| 1. | Passive immunity | 2. | Active immunity |
| 3. | Acquired immunity | 4. | Autoimmunity |

| 1. | Preformed antibodies need to be injected to treat the bite by a viper snake. |
| 2. | The antibodies against smallpox pathogen are produced by T - lymphocytes. |
| 3. | Antibodies are protein molecules, each of which has four light chains. |
| 4. | Rejection of a kidney graft by the recipient is the function of B-lymphocytes. |

| 1. | Injection of snake antivenom against snake bite is an example of active immunisation. |
| 2. | If due to some reason, B-and T-lymphocytes are damaged, the body will not produce antibodies against a pathogen. |
| 3. | Injection of dead/inactivated pathogens causes passive immunity. |
| 4. | Certain protozoans have been used to mass produce hepatitis B vaccine. |
A person Iikey to develop tetanus is immunized administering

2. Preformed antibodies
3. Wide spectrum antibiotics
4. weakened germs

2. Activated pathogens
3. Harvested antibodies
4. Gamma globulin
