Origin and Evolution of life Quiz-17

Dear Readers,

NEET is the most famous and important medical entrance examination held in our country. This exam is an objective type, an offline test which includes 4 sections namely– Physics, Chemistry, Botany, and Zoology. The maximum marks that can be scored are 720 marks and have 180 questions. About half of the paper consists of questions from Biology, as the NEET exam essentially focuses on capacitating students to go for seats in medical courses. One of the most significant and crucial sections in the NEET exam is of Biology. It comprises of theories, descriptions, discoveries, diagrams, definitions, explanations of differences, and relations. The majority of the topics covered in the NEET syllabus are from the NCERT syllabus of Class 11 & 12 and other related sources become part of the rest of the syllabus. Clear Exam curates a list of articles selected by professionals who recommend the highly vital topics for NEET exams. The table below takes you directly to the respective topic where the in-depth article and the MCQs are available for an easy and productive learning experience. Prior to solving NEET question papers or practicing mock tests, you must ensure to study the basic concepts in NEET and practice a few sample questions related to this exam. Students will be covered for all their studies as the topics are available from basics to even the most advanced. .

Q1. Which of the following branch of biology helps in to know the existence of coal?
  •  Palaeobotany
  •  Bacteriol ogy
  •  Economic botany
  •  Ecology
Palaeobotany is the branch of Palaeontolgoy in which we study the fossils of plants. Coal was formed by large pteridophyte in prehistoric time

Q2. A population is in Hardy-Weinberg equilibrium for a gene with only two alleles. If the gene frequency of an allele’A’ is 0.7, genotype frequency of ‘a’ is
  •  0.21
  •  0.42
  •  0.36
  •  0.7

Q3. Who wrote the famous book Origin of Species
  •  Lamarck
  •  Darwin
  •  de Vries
  •  Mendel
Drawin’s work was published with R Wallace’s paper in the “Proceeding’s of Linnean Society’ in 1859, latter on Darwin published his famous book “Origin of Species”.

Q4. The primates nearest to humans in the evolutionary line is
  •  New world monkeys
  •  Apes
  •  Lemurs
  •  Echidna
Humans blood group are as A, AB, B, O. Blood groups A and B are also found in apes, but not in monkeys. This indicates that human beings are more closely related to apes than to monkeys

Q5.The gases condensed under …A… and formed the galaxies of the present day universe. In the solar system of the milky way galaxy, earth was supposed to have been formed about …B… back. There was no atmosphere …C… on the earth. Water vapour, …D… carbon dioxide and ammonia released from molten mass covered the surface. Choose the correct option for A, B, C and D to complete the given paragraph with reference to NCERT textbook
  •  A-Gravitation, B-4.5 billion years, C-Early, D-Methane
  •  A-Acceleration, B-4.5 billion years, C-Early, D-Methane
  •  A-Acceleration, B-4.5 billion years, C-Early, D-Ethane
  •  A-Gravitation, B-4.5 billion years, C-Early, D-Ethane
  A-Gravitation, B-4.5 billion years, C-Early, D-Methane

Q6. Origin of different types of beaks occur due to
  •  Natural selection
  •  Interspecific competition
  • Genetic drift
  •  Interspecific variation
The possibility of the new characters is always present in the organisms. But, it is the condition of nature, which gives the chance of that character to come forward. Therefore any new character is favoured because of natural selection

Q7.Stings of honey bee and the stings of scorpion are I. analogous organs II. heterologous organs III. homologous organs IV. vestigial organs The correct combination is
  •  III and IV
  •  II and III
  •  I and II
  •  I and III
Analogous organs (Convergent evolution). Convergent evolution describes the acquisition of the same biological trait in an unrelated lineages. The wings are the classic example of convergent evolution in action. Flying insects, birds and bats have all evolved the capacity of flight independently. They have ‘convergent’ on this useful trait. The ancestors of both bats and birds were terrestrial quadrupeds, and each of them had independently evolved powered flight via adaptations are superficially ‘wing-shaped’, they are substantially dissimilar in construction. The bat wing is a membrane stretched across four extremely elongated fingers, while the airfoil of the bird wing is made of feathers, which are strongly attached to the forearm the ulna and the highly fused bones of the wrist and hand the carpometacarpus, with only tiny remnants of two fingers remaining, each anchoring a single feather. Both bats and birds have retained the thumb for specialized functions. So, while the wings of bats and birds are functionally convergent, they are not anatomically convergent Analogous organs. Analogous Organs The organs which have similar functions but are different in their details and origin are called analogous organs. The analogous organs shows convergent evolution 


  •  Analogous organs
  •  Homologous organs
  •  Convergent evolution
  •  All of these
Homologous organs. Homologous Organs The organs which have the same fundamental structure but are different in functions are called homologous orangs. These organs follows the same basic plan of organization during development. But in adult condition, these organs are modified to perform different function as an adaptation to the different environment. Homologous organs are the resultant of divergent evolution Implants homologous organs may be a those of Bougainvillea or a tendril of Cucurbita, both arising in the axillary position

Q9.Age of fossils in the past was generally determined by radio-carbon method and other methods involving radioactive elements found in the rocks. More precise methods, which were used recently and led to the revision of the evolutionary period for different groups of organisms, include
  •  Study of carbohydrates/ proteins in fossils
  •  Study of conditions of fossilization
  •  Electron spin resonance (ESR) and fossil DNA
  •  Study of carbohydrates/proteins in rocks
Electrons Spin Resonance (ESR) measures number of charges occupying deep traps in crystal band gap. The basic principle of ESR is same as those for luminescene, i.e., electorns become trapped and stored as a result of ionising radiations, e.g., dating of tooth enamel.

Q10. A baby has been born with a small tail. It is the case of exihibiting
  •  Retrogressive evolution
  •  Mutation
  •  Atavism
  • metamorphosis
The phenomenon of sudden reappearance of some ancestral features is called atavism. Appearance of ancestral characters in the new born such as large canines, thick body hairs, monstral face, short temporary tails, gill slits, additional pairs of nipples, etc, are example of atavism.
