  1. A Adeno virus
  2. B DNA retrovirus
  3. C RNA retrovirus
  4. D Adeno retrovirus
Show answer & explanation

Correct answer: C

3
A disease which can be transferred from mother to child through placenta is
  1. A German measles
  2. B Syphilis
  3. C AIDS
  4. D All of these
Show answer & explanation

A person who met with road accident is likely to develop tetanus. He is immunised by administering
  1. A Weakened germs
  2. B Dead germs
  3. C Preformed antibodies
  4. D Wide spectrum antibiotics
Show answer & explanation

Correct answer: C

Preformed antibodies are injected in such injury as pathogen i.e., Clostridium tetani produces a neurotoxintetanospasmin and a quick response is required to stop the action of antigen which is not done by the formation of our own antibodies as it takes time.
Weakened germs and dead germs are used in vaccine to develop immunity against them.
Wide spectrum antibiotics are used when a person is suffering from many bacterial diseases or infections but not for a single disease/infection.

Correct answer: D

Cocaine and its derivatives are stimulants, canabinoids are hallucinogens.
6
A non-specific type of defense that is present at the time of birth is
  1. A Acquired immunity
  2. B Humoral immune response
  3. C Cell mediated immunity
  4. D Innate immunity
Show answer & explanation

Correct answer: D

It is non-specific as it acts against any type of foreign agent.
Acquired Immunity- It is pathogen specific and its initiated when a host encounters pathogen during first attack
Humoral Immunity- Type of acquired immunity- B-lymphocyte mediated in which antibodies are produced.
Cell mediated immunity-T-lymphocyte mediated.
7

  1. A Radiation therapy
  2. B Use of $\alpha$-interferon
  3. C Surgery
  4. D Use of mitotic inhibitors
Show answer & explanation

Correct answer: B

$\alpha$-interferous are biological response modifiers which help in destroying the tumor by activating the immune system.
