1. I and II only

2. I and III only

3. II and III only

4. I, II and III

Match each disease with its correct type of vaccine.

Codes:

(2) Cell-mediated immune response

(3) Hormonal immune response

(4) Physiological immune response

Which of the following sets of diseases is caused by bacteria?

Which of the following is correct regarding AIDS causative agent HIV?

(2) HIV is enveloped virus that contains two identical molecules of single-stranded RNA and two molecules of reverse transcriptase

(3) HIV is not enveloped retrovirus

Asthma may be attributed to
1. allergic reaction of the mast cells in the lungs
2. inflammation of the trachea
3. accumulation of fluid in the lungs

In higher vertebrates, the immune system can distinguish self-cells and non-self. If this property is lost due to genetic abnormality and it attacks self-cells, then it leads to 
1. graft rejection 
2. auto-immune disease 
3. activate immunity 
4. allergic response
