Weekly Quiz Competition

Question 1
1 / -0

Animals are protected from poachers in:

A
Zoological Parks

B
Botanical Parks

C
Both (a) and (b)

D
None of these

Solution

A zoological park is a concept of keeping the animals in a confined area which is more or less similar to their natural environment, here the animals are provided with shelter, food and veterinary care. They are also open for public display. Here, animals are not harmed in any manner nor is poaching allowed.
So, the correct answer is 'Zoological Parks'
Question 2
1 / -0

Degradation of biodiversity occurs because of -

A
hunting of animals

B
deforestation

C
pollution

D
all of the above

Solution

degradation of biodiversity occurs because of ;
Hunting of animals: Many animals are hunted for their teeth, skin, bone, tusks, horns,meat etc. due to this not only does the existence of these organisms become endangered but also other organisms that are dependent on them.
Deforestation: Indiscriminate felling of trees for ubanisation, industrialization, using wood for fuel and furniture also results in loss of trees and habitat for many other organisms.
pollution: The flora and fauna of a region are adversely affected due to pollution of soil, water and air. Major contributors to pollution being industries and sewage.
So, the correct answer is 'all of the above'
Question 3
1 / -0

In our national park, protection is provided to -

A
Flora only

B
Flora and fauna

C
Fauna only

D
Entire ecosystem

Solution

In National parks protect is provided not only to the flora and fauna but also to the tribes, monuments etc that fall within the boundaries of the park.
So, the correct answer is 'Entire ecosystem'
Question 4
1 / -0

Conservation means-

A
we have to stop the use of resources completely.

B
we have to use the resources wisely and judiciously

C
we have to protect the resources by just not using it as per our demands.

D
all of the above.

Solution

Conservation means using of resources wisely and judiciously so that the non-renewable resources like coal and petroleum do not get extinct, the trees in forests are not felled indiscriminately for construction, for fuel and furniture and other forest products. This will not only limit the amount of pollution, the magnitude of natural calamities like floods but also provide these resources for the forthcoming generations.
So, the correct answer is 'we have to use the resources wisely and judiciously'
Question 5
1 / -0

Which of the following countries has the highest biodiversity

A
Brazil

B
South Africa

C
Russia

D
India

Solution

Brazil falls in the area of Amazon rainforest which is having the highest biodiversity in the world.
So, the correct answer is 'Brazil'
Question 6
1 / -0

Which one of the following is not a feature of biodiversity hot spots?

A
Large number of species

B
Abundance of endemic species

C
Mostly located in the polar regions

D
Mostly located in the tropics

Solution

Polar regions have poorest biodiversity because of low sunlight, very low temperature and negligible precipitation.
So, the correct answer is 'Mostly located in the polar regions'
Question 7
1 / -0

The three top most major crops of the world in terms of major staple food are?

A
Maize > Rice >Wheat

B
Rice > Wheat > Maize

C
Wheat > Maize > Rice

D
Rice > Maize >Wheat

Solution

A staple food, sometimes simply referred to as a staple, is a food that is eaten routinely, and in such quantities that it constitutes a dominant portion of a standard diet in a given population, supplying a large fraction of the needs for energy-rich materials and generally a significant proportion of the intake of other nutrients as well. Most people live on a diet based on just a small number of staples.
Staple foods vary from place to place, but typically they are inexpensive or readily available foods that supply one or more of the three organic macronutrients needed for survival and health: carbohydrates, proteins, and fats.
Wheat (Triticum spp.) is a cereal grain, originally from the levant region of the Near East but now cultivated worldwide. In 2013, world production of wheat was 713 million tons, making it the third most-produced cereal after maize (1,016 million tons) and rice (745 million tons).
Question 8
1 / -0

Co-varieties of sugarcane obtained red rot resistance from

A
Saccharum munja

B
S. spontaneum

C
S. arundinaceum

D
S. edula

Solution

S.spontaneum has been the chief source of resistance to red rot and these forms are usually resistant to Pythium root rot and largely susceptible to smut. It is widely used in crosses as source of disease resistance in many present day hybrids
Question 9
1 / -0

Dwarf variety of wheat was developed by

A
M.S. Swaminathan

B
Vavilov

C
Borlaug

D
Both A and C

Solution

Norman Borlaug developed a special breed of dwarf wheat that resisted a wide spectrum of plant pests and diseases and produced two to three times more grain than the traditional varieties. During the period from 1949-55, M S Swaminathan undertook research on potato, wheat, rice and jute genetics, after which he worked on Mexican dwarf wheat varieties.
Question 10
1 / -0

Cryopreservation is carried out at

A
-10 to -20$$^{0}$$C

B
-50 to -60$$^{0}$$C

C
-196$$^{0}$$C

D
-100$$^{0}$$C

Solution

Cryopreservation is the preservation of cells and tissue by freezing.
Cryopreservation is based on the ability of certain small molecules to enter cells and prevent dehydration and formation of intracellular ice crystals, which can cause cell death and destruction of cell organelles during the freezing process.
Most systems of cellular cryopreservation use a controlled-rate freezer. This freezing system delivers liquid nitrogen into a closed chamber into which the cell suspension is placed. Careful monitoring of the rate of freezing helps to prevent rapid cellular dehydration and ice-crystal formation. In general, the cells are taken from room temperature to approximately $$−190^0$$C in a controlled-rate freezer. The frozen cell suspension is then transferred into a liquid-nitrogen freezer maintained at extremely cold temperatures with nitrogen in either the vapour or the liquid phase. Cryopreservation based on freeze-drying does not require use of liquid-nitrogen freezers.
