Identify the wrong statement with reference to immunity.
When exposed to antigen (living or dead) antibodies are produced in the host’s body. It is called “Active immunity”.
When ready-made antibodies are directly given, it is called “Passive immunity”.
Active immunity is quick and gives full response.
Fetus receives some antibodies from mother, it is an example for passive immunity.
Which of the following immune responses is responsible for rejection of kidney graft?
Cell-mediated immune response
Auto-immune response
Humoral immune response
Inflammatory immune response
Colostrum, the yellowish fluid, secreted by mother during the initial days of lactation is very essential to impart immunity to the new born infants because it contains
immunoglobulin A
natural killer cells
monocytes
macrophages.

Psoriasis
Rheumatoid arthritis
Alzheimer’s disease
Vitiligo
MALT constitutes about (NEET 2017) percent of the lymphoid tissue in human body.
20%

Antivenom injection contains preformed antibodies while polio drops that are administered into the body contain
gamma globulin
attenuated pathogens
activated pathogens
harvested antibodies
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 selfcells, then it leads to
autoimmune disease
active immunity
allergic response
graft rejection
If you suspect major deficiency of antibodies in a person, to which of the following would you look for confirmatory evidence?
Haemocytes
Serum globulins
Fibrinogen in plasma
Serum albumins

Which of the following is correct regarding AIDS causative agent HIV?
HIV is enveloped virus containing one molecule of single-stranded RNA and one molecule of reverse transcriptase.
HIV is enveloped virus that contains two identical molecules of single-stranded RNA and two molecules of reverse transcriptase.
HIV is unenveloped retrovirus.
HIV does not escape the immune response.
HIV that causes AIDS, first starts destroying
helper T-lymphocytes
thrombocytes

leucocytes.
At which stage of HIV infection does one usually show symptoms of AIDS?
Within 15 days of sexual contact with an infected person
When the infected retro virus enters host cells

Which one of the following statements is correct with respect to AIDS?
The HIV can be transmitted through eating food together with an infected person.
Drug addicts are least susceptible to HIV infection.
AIDS patients are being fully cured cent per cent with proper care and nutrition.
The causative HIV retrovirus enters helper T-lymphocytes thus reducing their numbers.
Human immuno deficiency virus (HIV) has a protein coat and a genetic material which is
double stranded RNA
double stranded DNA
single stranded DNA
single stranded RNA.
Which of the following statements is not true for cancer cells in relation to mutations?
Mutations inactivate the cell control.
