Question 1
1 / -0

Select the wrong pair.

A
Haldane _____ Hot dilute soup

B
Oparin _____ Protobionts

C
Spallanzani ______ Abiogenesis

D
Fox _____ Coacervates

E
Redi ______ Biogenesis
Question 2
1 / -0

Which is correct order of increasing geological time scale for a hypothetical vertebrate evolution?

A
Cenozoic, Mesozoic, Palaeozoic, precambrain

B
Cenozoic, Palaeozoic, Mesozoic, precambrain

C
Precambrain, cenozoic, Palaeozoic, mesozoic

D
Precambrian, Palaeozoic, Mesozoic, cenozoic
Question 3
1 / -0

If a population has dominant phenotype in 1600 individuals out of 2000 then calculate the frequency of heterozygote.

A
494

B
256

C
128

D
356

Solution

A.Correct option - A
B.Explanation for correct option -A
According to Hardy-Weinberg equilibrium-
p + q=1
Where p is the frequency of dominant frequency and q is the frequency of recessive allele.
Homozygous dominant individuals are-
2000 ×p = 1600
2000×q= 400
$$q^2$$= Total - $$p^2$$
=2000 - 1600
= 400
$$q^2$$ in 2000 sec will be 400/2000
$$q^2$$ = 0.2
$$q^2$$ = 0.447
We know, p + q= 1
p= 1- 0.447
p= 0.553
Frequency of hetrozygote are-
2pq= 2 x 0.447 x 0.553
= 0.494
So, frequency is 494.
Question 4
1 / -0

The theory of special creation was not objected by which of the following statements?

A
Existing life forms share similarities to varying degrees not only among themselves but also with life forms that existed millions of years ago.

B
Many life forms do not exist now.

C
There has been gradual evolution of life forms.

D
The Earth was about 4000 years ago.
Question 5
1 / -0

In laboratory experiments, two species of the protist Paramecium(species $$1$$ and $$2$$) were grown alone and in the presence of the other species. The following graphs show growth of species $$1$$ and $$2$$, both alone and when in mixed culture with the other species.
Which of the following conclusions can be drawn from the graphs?

A
Competitive exclusion occurred in these experiments

B
Both species are affected by interspecific competition but specie $$1$$ is less affected

C
Both species are affected by interspecific competition but specie $$2$$ is less affected

D
Both species are affected equality by interspecific competition
Question 6
1 / -0

Hardy - Weinberg equilibrium cannot operate if:

A
Selective mating occurs and only useful alleles get chance to appear in next generation.

B
Mating is at random and all alleles get equal chance to appear in next generation.

C
Mutations and gene flow are absent.

D
Populations are largely sized.

I and III

B
II and IV

C

A

B
Abiogenesis

C
Both (A) and (B)

D

Question 10
1 / -0

One of the following is not true regarding biological evolution. Identify the wrong one:

A
Evolution through natural selection might have started when cellular forms with difference in metabolic capacity originated.

B
Rate of appearance of new forms is linked to life span and life cycle of organisms.

C
Speciation occurs due to the accumulation of acquired characters.

D
Animals that are better adapted have more resource utilisation and they leave more number of progeny.
