Weekly Quiz Competition

Question 1
1 / -0

First photosynthetic organisms to appear on earth were:

A
Bacteria

B
Green algae

C
Cyanobacteria

D
Bryophytes

Solution

C. Cyanobacteria
Solution : Cyanobacteria or blue green algae were the first organisms that appeared on earth and underwent anoxygenic photosynthesis and gave out oxygen and made the earth oxygenic in a few million years.
So the correct answer is "Cyanobacteria".
Question 2
1 / -0

Which experiment suggests that simplest living organism could not have originated spotaneously from non-living matter?

A
Microbes did not appear in stored meat.

B
Microbes appeared in decaying organic matter.

C
Larvae could appear in decaying organic matter.

D
Meat was not spoiled when heated and kept in sealed vessel.
Question 3
1 / -0

Who gave the theory which is known as primary abiogenesis?

A
Oparin

B
Haldane

C
Miller

D
Urey
Question 4
1 / -0

Which of the following has been basic to origin of life ?

A
Carbohydates

B
Proteins

C
Nucleic acid

D
Nucleoproteins
Question 5
1 / -0

Which is the correct sequence of events in the origin of life :
I. Formation of protobionts
II. Synthesis of organic monomers
III. Synthesis of organic polymers
IV. Formation of DNA based genetic systems

A
II, III, IV, I

B
I, III, III, IV

C
I, III, II, IV

D
II, III, I, IV
Question 6
1 / -0

The term hot dilute soup was given by :

A
Haldane

B
Urey

C
Oparin

D
None of the above
Question 7
1 / -0

What is correct arrangement of periods of palaeozoic era in ascending order in geological time scale))

A
Cambrian $$\rightarrow $$ Devonian $$\rightarrow $$Ordovician $$\rightarrow $$ Silurian $$\rightarrow $$ Carboniferous $$\rightarrow $$ Permian

B
Cambrian $$\rightarrow $$ Ordovician $$\rightarrow $$Silurian $$\rightarrow $$ Devonian $$\rightarrow $$Carboniferous$$\rightarrow $$ Permian

C
Cambrian $$\rightarrow $$ Ordovician Devonian $$\rightarrow $$ Silurian $$\rightarrow $$ Carboniferous $$\rightarrow $$ Permian

D
Silurian $$\rightarrow $$4 Devonian $$\rightarrow $$Cambrian $$\rightarrow $$ Ordovician Permian $$\rightarrow $$ Carboniferous

Solution

A geologic time scale is natural advancement is the event of homologous and minimal organs. Homologous organs are those which have the regular inception and are based on a similar central example yet they perform diverse capacities and have distinctive appearances, e.g. whale's flipper, bat's wings, feline's paws, steed's front legs, fledgling's wings, bull's front legs, and human hands.
So, the correct option is 'Cambrian → Ordovician →Silurian → Devonian →Carboniferous→ Permian'.
Question 8
1 / -0

Jurassic period of mesozoic era is characterized by

A
Flowering plants and first dinosaurs appear

B
Gymnosperms are dominant plants and first birds appear

C
Radiation of reptiles and angiosperms appear

D
Dinosaurs become extinct and angiosperms appear

Solution

The principal crude winged animal, Archaeopteryx, likewise shown up. A Jurassic period is the second topographical time of Mesozoic time. In this period, the gymnosperms were prevailing and the plants included greeneries, cycads, Ginkgo, surges, and conifers.
So, the correct option is 'Gymnosperms are dominant plants and first birds appear'.
Question 9
1 / -0

Oparin and Haldane proposed :

A
Theory of natural selection

B
That mutation caused speciation

C
That migration affects genetic equilibrium

D
That the first form of life could have come from prexisting nonliving organic molecules.

E
That evolution of life forms had been driven by use and disuse of organs.
Question 10
1 / -0

Theory of origin of life was proposed by :

A
Tansley

B
Oparin

C
Darwin

D
Malthus
