Choose the correct statement with reference to organic evolution. I. Flippers of whale and wing of bat exhibit analogy. II. Wing of butterfly ,and wing of bird exhibit homology. III. Organs with dissimilar structure are called analogous organs. IV. Organs with similar structure and origin arc called homologius organs.A. I and IIB. II and lVC. I and IIID. III and IV |
|
Answer» Correct Answer - D Homologous structure have the same embroynic origin and basic structure but they do not perform same function . Flippers of whale and wings of bat exbhilit homology The analgous organs are the structure which are different in their basic structure and development origin , but appear similar and perform similar function . Wings of buttergly and wings of bird exbhilit analogy |

Choose the wrong statementA. Louis Pasteur demonstrated that life comes only from pre-existing lifeB. SL , Miller observed that electric discharger in a flask containg `CH_4,H_2,NH_3` and water vapour at `800^@C` formed amino acidsC. Flippers of penguins and dolphins are examples for homologyD. Homology indicates common ancestry |
|
Answer» Correct Answer - C All the statementts given are correct expect (c ) . Flippers of penguins and dolphins are analgous organs because these are functionlly similar , but are anatiomaclly different . This results in the convergent evolution |

Asseration Amphibians have evolved from fishes Reason Archaeopteryx is a fossil linking fishes and amphibiansA. Both Assertion and Reason are true, but Reason is the correct explanation of AssertionB. Both Assertion and Reason are true, but Reason is not the correct explanation of AsserationC. Assertion is true, but Reason is falseD. Asseration is false , but Reason is true |
|
Answer» Correct Answer - C Amphibians have envolved from fishes . Long fishes are the connecting link between fishes and amphbians Archaeoptery is a connecting link or transitional stage between the replities and birds , as it processes both replittian as well as aian characters |

Assertion : From evolutionary point of view, human gestation period is believed to be shortening. Reason : One major evolutionary trend in humans has been the larger head undergoing relatively faster growth rate in the foetal stage.A. Both Assertion and Reason are true, but Reason is the correct explanation of AssertionB. Both Assertion and Reason are true, but Reason is not the correct explanation of AsserationC. Assertion is true, but Reason is falseD. Both Asseration and Reason are false |
|
Answer» Correct Answer - D The human would require more getation period (should have been 21 months as compared to 9 months and will increase ). Similarly , the head size is increasing (especially the frontal brain) , hence growth rate needs to increase , but surprisingly , most of the brain growth occurs after birth till two years (when the anterior fotanellac close at 18 months ) and some till 30 years when finally the cranial structures close Thus, an increase in brain/skull size would require increase in gestation period |

| 57. |
Evidence form biochemistry and physiology can be seen formA. metabolismB. enzymesC. hormonesD. All of these |
| Answer» Correct Answer - D | |
| 58. |
Assertion : Comparative biochemistry provides a strong eviednce in favour of common ancestory of living beings. Reason : Genetic code is universal.A. Both Assertion and Reason are true, but Reason is the correct explanation of AssertionB. Both Assertion and Reason are true, but Reason is not the correct explanation of AsserationC. Assertion is true, but Reason is falseD. Asseration is false , but Reason is true |
|
Answer» Correct Answer - B Genetic codes are applicable universally because a codon specifies the same amino acid from a virus to a treee or human beings . Convincing evidence of common ancestry also comes from the similarties in the biochemical composition , reaction and physiological activities of living beings like metaboic process , enzyme , cytochomace-c, hormones haemoglobin , lymph, etc |
