A person applies hydrogen peroxide on his wound. This is to kill

  1. Anaerobic bacteria

  2. Aerobic bacteria

  3. Fungi

  4. Protozoa
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A person applies hydrogen peroxide on his wound. This is to kill anaerobic bacteria. Anaerobic bacteria cannot survive in the presence of oxygen. The hydrogen peroxide bubbling releases oxygen. Hence, due to the released oxygen, anaerobic bacteria will be killed. However, it also affects the healthy cells of the body. This in turn slows down the process of wound healing.

Thus, the correct answer is 'Anaerobic bacteria.'

Antiseptics are

  1. hormones

  2. enzymes

  3. chemical substances

  4. all
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

These are mild chemical substances which, when applied on the body, kill germs. These substances are in such mild concentration that they cause no harm to the skin and body. Lysol, carbolic acid (phenol), Iodine, benzoic acid, Mercurochrome, boric acid etc in dilute solution are good antiseptics. Certain antibiotic creams also serve the same purpose.

Ozone is passed through swimming pool because it

  1. Absorbs UV radiations

  2. Acts as disinfectant
  3. Easily available from $O _2$

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Ozone is an effective disinfectant. It is passed through the swimming pool and is used in water treatment units because of the following reasons:

1. It improves the smell and visibility of the water.
2. It destroys bacteria and viruses by causing their oxidation.
3. It oxidises metals like manganese, iron and sulphur into the soluble particles and so these can be easily filtered out.
4. It has a bleaching effect on the discoloured water.
Hence, the correct answer is 'Acts as disinfectant'.

Multiple choice zoology diseases and immunity active and passive immunity immunity related disorders and problems aids to health

The correct statement about active immunity is:

  1. It provides immediate relief

  2. It is long lasting immunity with no side effects

  3. ATS is used for active immunisation

  4. It cross the placental barrier
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Active immunity is the antibody response produced by the body when exposed to pathogens, vaccines etc. It is a long lasting immunity and has no side effects as these are WBCs produced by the body. 

So, the correct answer is 'it is long lasting immunity with no side effects''

Multiple choice zoology diseases and immunity active and passive immunity immunity related disorders and problems aids to health

Active immunity development is related to ______________.

  1. NK cells

  2. Memory cells
  3. $T _H$ cells
  4. $T _S$ cells
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Active immunity is established when the immune system encounters an antigen and mounts a primary response, leaving behind long-lived memory B and T cells that protect against subsequent infections.

Von Behring was awarded the Nobel Prize for the discovery of passive immunity

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Emil von Behring was awarded the first Nobel Prize in Physiology or Medicine in 1901 for his discovery of serum therapy for diphtheria. He and Shibasaburo Kitasato showed that serum from rabbits immunized with tetanus toxin could prevent tetanus in rabbits. Erlich's work demonstrating that increasing doses of bacterial toxins could provide immunity against lethal doses of toxin was the basis for the serum therapy findings. His work also led to the concepts of active and passive immunization, and to his Nobel Prize in 1908 awarded for establishing the field of humoral immunity. It is fitting to highlight Erlich's contribution to the initial conception of passive immunization in 2015, the 100 year anniversary of his death.


So, the correct option is 'True'.
