Origin and Evolution of Life Quiz-12
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.

Q4. Swan-necked flask experiment proved
Solution
Pasteur performed a swan-necked flasked experiment for proving biogenesis, according to biogenesis, all the living oranisms have originated from other living organisms. This experiment disproved the concept of spontaneous generation completely.

Q5.The concept that the species have changed over long period of time is known as
Solution
Organic means living. Evolution means change through time. Ecology is the study of organisms in their environment. Embryology is the study of developing organisms. Spontaneous generation is the theory that living things can arise from the non-living materials

Q6. Identify the phenomenon in which the members of a species do not interbreed with the members of other species or same species
Solution
When the members of a species do not interbreed with the members of other species or same species due to differential modification is called reproductive isolation. The criterion of the reproductive isolation can not be used in asexual organisms

Q7.Darwin in his ‘natural selection theory’, did not believed in any role of which one of the following in organic evolution?
Solution
Natural selection theory of Darwin did not belive in any role ofdiscontinuous variations. Darwin called these variations as ‘sports’, while Hugo de Vries used the term mutation to these variations. These variations are sudden heritable changes, which can occur in any stage of development.

Q8.An important evidence in favour of organic evolution is the occurrence of
Solution
Presence of homologous and vestigial organs are important evidences in favour of organic evolution. They show divergent evolution.

Q9.The main point of Darwin’s theory is
Solution
Main point of Darwin’s theory is Natural Selection.
Main point of Darwin’s theory is Natural Selection.
Q10. The natural selection that acts against change in the form and keeps the population constant through the time is
Solution
Stabilizing selection acts in the absence of large scale environment change, therefore, it keeps a population genetically constant.
