Weekly Quiz Competition

Question 1
1 / -0

Dinosaurs were dominant during

A
Jurassic period

B
Cretaceous period

C
Triassic period

D
Palaeocene period

Solution

Dinosaurs lived somewhere in the range of 230 and 65 million years back, in a period known as the Mesozoic Era. This was a huge number of years before the main present-day people, Homo sapiens, showed up. Researchers partition the Mesozoic Era into three periods: the Triassic, Jurassic, and Cretaceous.
So, the correct answer is 'Jurassic'
Question 2
1 / -0

Organic compounds that first evolved on earth and required for the origin of life were:

A
Urea and amino acids

B
Proteins and nucleic acids

C
Proteins and amino acids

D
Urea and nucleic acid
Solution
- Proteins and nucleic acids are the two most basic compounds required for the sustenance of life.
- Proteins provided a limiting membrane and boundary to primitive entities and nucleic acids are important information molecules, which are required to build self-replicating entities. Option B is correct
Question 3
1 / -0

Experimental proof that some simple molecules like $$H_2 , NH_3 , CH_4 $$ and $$H_2 O $$ gave provided by :

A
Lamarck

B
Darwin

C
Stanley

D
Harold Urey
Question 4
1 / -0

Life originated in :

A
Air

B
Soil

C
Mountains

D
Water
Question 5
1 / -0

The early stage human embryo distinctly possesses

A
Gills

B
Gill slits

C
External ear (pinna)

D
Eye brows

Solution

Early embryos, organisms of various vertebrates, after one another in having certain comparable structures, similar to gill slits, notochord, tail.
So, the correct option is 'Gill slits'.
Question 6
1 / -0

Dinosaurs were present during the

A
Palaeozoic era

B
Coenozoic era

C
Mesozoic era

D
Precambrian

Solution

Dinosaurs lived between around 245 and 66 million years back, in a period known as the Mesozoic Era. This was a huge number of years before the main present-day people, Homo sapiens, showed up.
So, the correct option is 'Mesozoic era'.
Question 7
1 / -0

The classical example of adaptive radiation during formation of new species is

A
Marsupials of Australia

B
Darwin's finches

C
Giant tortoise

D
All of the above

Solution

Darwin's finches are an established case of a versatile radiation. Their regular predecessor touched base on the Galapagos around two million years prior. Amid the time that has passed Darwin's finches have developed into 15 perceived species varying in body estimates, mouth shape, melody and nourishing conduct. Changes in the size and type of the snout have empowered distinctive species to use diverse nourishment assets such us creepy crawlies, seeds, nectar from desert flora blooms and in addition blooded from iguanas, all determined by Darwinian determination.
So, the correct option is 'Marsupials of Australia'.
Question 8
1 / -0

Microspheres were developed artificially by :

A
Oparin

B
Fox

C
Bahadur

D
Daemer
Question 9
1 / -0

Oparin's theory is based on :

A
Artificial synthesis

B
Spontaneous generation

C
God's creation

D
Panspermia
Question 10
1 / -0

Mammals like Whale, Dolphin. Bat. Monkey and Horse have some common characters but also show conspicuous differences. This is due to phenomenon of

A
Divergence

B
Convergence

C
Genetic drift

D
Normalisation

Solution

Divergent evolution is the procedure whereby bunches from a similar normal predecessor develop and collect contrasts, bringing about the arrangement of new species. Dissimilar advancement may happen as a reaction to changes in abiotic factors, for example, a change in ecological conditions, or when another speciality ends up accessible.
So, the correct option is 'Divergence'.
