Which of the following is wrongly matched?

zoology biodiversity and conservation hotspots and methods of conservation biodiversity: conservation conservation of biodiversity basis of classification in animals basis of the classification of animals criteria for animal classification five kingdoms of living organisms biodiversity and need of classification biodiversity and classification

  1. Temperate zone - $20^{\circ}\, -\, 40^{\circ}$ latitude

  2. Hypolimnion -Thermal stratifications in lakes

  3. Ozone layer - Stratosphere

  4. Profundal zone - Dark zone

Show answer
Correct Option: A
Explanation:

The north temperate climate extends from the 'Tropic of Cancer' (approximately 23.5 north latitude) to the arctic circle (approximately 66.5 north latitude). The south temperate zone extends from the tropic of capricorn (approximately 23.5 south latitude) to the antarctic circle (at approximately 66.5 south latitude). 

Ecological amplitude of a species is related to

  1. Zones of stress

  2. Zone of optimum tolerance range of a factor

  3. Area with zones of optimum tolerance ranges of all determining factors

  4. None of the above

Show answer
Correct Option: C

Latitude range with maximum species diversity is

  1. $23.5^0 N -66.5 ^0 N $

  2. $23.5^0 S -66.5 ^0 S $

  3. $23.5^0 N -23.5 ^0 S $

  4. $66.5^0 N -66.5 ^0 S $

Show answer
Correct Option: C
Explanation:
  • Latitudinal gradients of biodiversity are biogeographic patterns that quantify the ways in which taxonomic, phylogenetic, functional, genetic, or phenetic biodiversity change with the latitudinal position on the surface of the earth.
  • Species richness, or biodiversity, increases from the poles to the tropics. So the latitude range with maximum species diversity is the equator region, which is option C.

Rate of photosynthesis is maximum at

zoology biodiversity and conservation hotspots and methods of conservation biodiversity: conservation conservation of biodiversity basis of classification in animals basis of the classification of animals criteria for animal classification five kingdoms of living organisms biodiversity and need of classification biodiversity and classification

  1. Equator

  2. Tropic of Cancer

  3. Tropic of Capricorn

  4. Arctic circle

Show answer
Correct Option: A
Explanation:

The rate of photosynthesis would be maximum at the equator because the the rate of photosynthesis depends on the light intensity. Maximum intensity of light occurs at the equator, and gradually decreases with increasing distance from the equator to the south and north poles. So the correct answer is 'Equator'.

Biological diversity day is

zoology biodiversity and its conservation hotspots and methods of conservation biodiversity: conservation conservation of biodiversity basis of classification in animals basis of the classification of animals criteria for animal classification

  1. 5 June

  2. 21 March

  3. 3 October

  4. 22 May

Show answer
Correct Option: D
Explanation:

Biodiversity day or the Biological diversity day is a UN sanctioned day celebrated internationally. It addresses the promotion of biodiversity issues. Currently, the day is held on May 22. Earlier, it was held on December 29 to celebrate the day in which the Convention on Biological Diversity came into action.

So, the correct answer is '22 May'.

The transgenic animals are those which have 

zoology biotechnology and its applications transgenic animals transgenic organisms applications of biotechnology

  1. Foreign RNA in all its cells

  2. Foreign DNA in some of its cells

  3. Foreign DNA in all its cells

  4. Both A and C

Show answer
Correct Option: C
Explanation:
Transgenic organism is one that has become transformed following the introduction of novel genes into its genome. It is most frequently achieved by integration of doned DNA sequences following their injection into the fertilised egg. This fertilised egg divides mitotically to form the whole organism so that all the cells of the organism will carry the transferred genes. The transferred genes are known as transgenes.
So, the correct answer is 'Foreign DNA in all its cells'.

Given are names of some transgenic animals. Identify the name of transgenic sheep.

Which of the following is not used to transfer the recombinant DNA into the host?

zoology biotechnology and its applications transgenic animals transgenic organisms applications of biotechnology

  1. Micro-injection method

  2. Gene gun method

  3. Bioreactors

  4. Disarmed pathogen vectors

Show answer
Correct Option: C
Explanation:
Bioreactors are considered as vessels in which raw materials are biologically converted into specific products by microbes, plant and animal cells or their enzymes. To produce large quantities of these products, bioreactors are used where large volumes (100-1000 litres) of culture can be processed. Bioreactor provides the optimal conditions for obtaining the desired product by providing optimum growth conditions such as temperature, pH, substrate, vitamins, oxygen and salts.
So, the correct answer is 'Bioreactors'.
