Weekly Quiz Competition

Question 1
1 / -0

Genomic DNA library is

A
Packing of donor DNA in a collection of vectors.

B
A collection of gene vectors.

C
Collection of organisms for extracting DNA.

D
A collection of literature about DNA.

Solution

A genomic library is a collection of total genomic DNA from a single organism. This DNA is packed in a population of identical vectors for storage. Each vector contains a different insert of DNA.

So, the correct option is 'Packing of donor DNA in a collection of vectors.'
Question 2
1 / -0

Let no one species encroach over the right and privileges of other species is the stanza from

A
Atharva Veda

B
Isha Upanishad

C
Kautilyas Arthashastra

D
Bhagvat Geeta

Solution

Isha Upanishad is one of shortest Upanishads, which is embedded as the final chapters of Shukla Yajurveda, the following stanza is found in this upanishad.
So, the correct answer is 'Isha Upanishad'
Question 3
1 / -0

Which one will be searched for obtaining maximum genetic diversity?

A
Recent varieties

B
Old varieties

C
Wild relatives

D
All of the above

Solution
Question 4
1 / -0

Which of the following ecosystems exhibits maximum genetic variations?

A
Tropical rain forests

B
Tropical evergreen forests

C
Coniferous forests

D
Temperate forests

Solution

Species diversity or genetic variation increases as one proceeds from high altitude to low altitude and high latitude to low latitude. Tropical rain forests are wet and dense. They exhibit maximum genetic variations due to increased temperature and rainfall. They show high animal and plants biodiversity.
Thus, the correct answer is 'Tropical rain forests.'
Question 5
1 / -0

Maximum genetic diversity of crop plants occurs where agriculture is

A
Run on commercial lines

B
Advanced

C
Rainfed

D
Primitive

Solution
Question 6
1 / -0

Species diversity increases as one proceeds from

A
High altitude to low altitude and high latitude to low latitude

B
Low altitude to high altitude and high latitude to low latitude

C
Low altitude to high altitude and low latitude to high latitude

D
High altitude to low altitude and low latitude to high latitude
Solution
- Species diversity increases as one proceeds from high altitude to low altitude and high latitude to low latitude. The temperature and seasonal variability increases with increased altitude and decreased latitude. Hence, this results in higher species diversity in these areas.
Thus, the correct answer is 'High altitude to low altitude and high latitude to low latitude.'
Question 7
1 / -0

Reason for diversity in living beings is __________________.

A
Short term evolutionary changes

B
Long term evolutionary changes

C
Mutations

D
Gradual change
Question 8
1 / -0

Tropical region occurs

A
At 2 $3^0$ N and 2 $3^0$ S

B
Between 2 $3^0$ N and 2 $3^0$ S

C
Between $0^0$ and 2 $3^0$ N

D
Between $0^0$ and 2 $3^0$ S

Solution

Tropical region occurs at 23 $^o$ N and 23 $^o$ S. The region is present at the equator. It is limited in latitude by the tropic of cancer in the north and the tropic of capricorn in the south.
Thus, the correct answer is '23 $^o$ N and 23 $^o$ S.'
Question 9
1 / -0

Number of known species of organisms on this earth is

A
5.0 million

B
3.2 million

C
1.7 million

D
1.32 million

Solution

A great biodiversity exists on our planet. Millions of living plants and animal species are flourishing on Earth. An approximate of 1.7 million organisms are known to exist. New species are getting discovered and recorded every year.
So, the correct answer is '1.7 million'.
Question 10
1 / -0

Bald Eagle had been at high risk of extinction due to its

A
Large size

B
Low reproductive potential

C
High trophic level

D
Change in migratory route

Solution

When there are no more individuals of a species (plant or animal) alive anywhere in the world, the species is said to be extinct. Extinction is also known as the process of dying out. The process is a completely natural part of evolution. But sometimes extinctions happen at a higher and a faster rate than usual. Factors such as large body size, small population, and position at a higher trophic level favour extinction.
So, the correct answer is 'High trophic level'.
