Question 1
1 / -0

Which one of the following experiment suggests that simplest living organisms could not have originated spontaneously from non-living matter?

A
Larvae could appear in decaying organic matter

B
Microbes did not appear in stored meat

C
Microbes appeared from unsterilized organic matter

D
Meat was not spoiled, when heated and kept sealed in a vessel
Solution
- The heating of meat killed the pre-existing micro-organisms and then the meat was kept in a sealed vessel, so that no organism can come from outside.
- In these conditions, no new microorganisms could be produced and meat would not be spoiled, because new micro-organisms cannot be produced by dead micro-organisms present in meat, and also no new micro-organisms are allowed from outside.
So, the correct answer is option D.
Question 2
1 / -0

The theory of hot dilute soup was given by

A
Oparin

B
Haldane

C
Urey

D
None of the above

Solution

The theory of hot dilute soup was given by Haldane to refer to prebiotic oceans, where organic bio molecules were produced from simple inorganic compounds
Question 3
1 / -0

Gases found in primitive atmosphere are

A
$$CH_4$$, $$NH_3$$, $$H_2$$, $$H_2O$$ (vapour form)

B
$$CH_4$$, $$NH_3$$, $$CO_2$$, $$H_2O$$

C
$$CH_4$$, $$H_2O$$, $$CO_2$$

D
$$CH_4$$, $$O_2$$, $$CO_2$$

Solution

Primitive atmosphere contained methane, ammonia, hydrogen, water vapours.
Question 4
1 / -0

Theory of catastrophism was supported by

A
Louis Pasteur

B
A.I. Oparin

C
Cuvier

D
Haldane

Solution

George Cuvier was the chief supporter of theory of catastrophism. It states that there had been several creations, each preceded by a catastrophic event due to some geological disturbances like volcanic eruption, upheaveling of earth; unprecedented increase in sea level etc.
Question 5
1 / -0

Coacervates were experimentally produced by

A
Urey and Miller

B
Jacob and Monod

C
Fischer and Huxley

D
Sidney Fox and Oparin
Solution
Correct Option: D

Explanation:
Coacervates were non-living colloidal aggregates of proteins and polysaccharides but did not have the ability to reproduce nor they developed a covering membrane of lipids.
Oparin and Sydney Fox held that large organic molecules synthesized abiotically on the primitive earth.
These molecules later came together spontaneously and due to intermolecular attraction formed large colloidal aggregates called coacervates.
Question 6
1 / -0

Most primitive living mammals which provide an evidence of organic evolution
from geographical distribution are found in

A
China

B
India

C
Australia

D
Africa

Solution

Prototherians the most primitive mammals which provide an evidence of
organic evolution from geographical distribution are found is Australia.
Question 7
1 / -0

The idea that life originates from preexisting life is referred as

A
Biogenesis theory

B
Special creation theory

C
Abiogenesis theory

D
Extraterrestrial theory

Solution

Biogenesis means life comes from pre existing life, as in modern earth. Now life comes from pre-existing life only but life actually evolved from non living components abiogenetically.
Question 8
1 / -0

Big bang theory was proposed by

A
Kant

B
Lemaitre

C
K. Bahadur

D
Weismann

Solution

Big bang theory was proposed by Lemaitre in 1931.
Question 9
1 / -0

Hardy-Weinberg equilibrium is known to be affected by gene flow, genetic drift, mutation, genetic recombination and

A
Evolution

B
Limiting factors

C
Saltation

D
Natural selection

E
Over production
Solution
- Any factor, which can disturb the frequency of alleles in a population is likely to affect the Hardy-Weinberg equilibrium.
- The alleles in a population can be altered by mutation, migration, genetic drift, recombination, and natural selection.
So, the correct answer is 'Natural selection'.
Question 10
1 / -0

The theory of evolution indicates that

A
Man evolved from monkeys

B
Monkey evolved from man

C
Man evolved from dinosaur

D
Man and apes had common ancestors

Solution

The theory of evolution states that the organism change gradually in order to adapt easily to the environment. The process by which an organism changes its heritable characteristics for better adjustment to the environment is known as evolution.
Man and apes had common ancestors known as chimpanzees. The chimpanzees during the course of evolution underwent changes and formed a more complex organism like man and apes. They share common mutation rates.
So, the correct answer is option D.
