Which compound has very important role in prebiotic evolution?
-
SO2
-
NO
-
CH4
-
SO3
Correct Answer
A. CH4Explanation
CH4, also known as methane, has a very important role in prebiotic evolution. Methane is a simple organic compound that can be produced by both geological and biological processes. It is thought to have been abundant on early Earth and may have played a crucial role in the formation of the first organic molecules. Methane can act as a precursor for the synthesis of more complex organic compounds, such as amino acids, which are the building blocks of proteins. Additionally, methane can serve as a source of energy for early life forms, making it an important compound in prebiotic evolution.Rate this question:

According to Oparin, which one of the following was not present in the primitive atmosphere of the earth?
-
Methane
-
Oxygen
-
Hydrogen
-
Water vapour
Correct Answer
A. OxygenExplanation
According to Oparin, oxygen was not present in the primitive atmosphere of the earth. Oparin's theory suggests that the early atmosphere was composed mainly of methane, hydrogen, and water vapor. Oxygen was absent because it was primarily produced by photosynthetic organisms, which evolved later in the history of the earth. This lack of oxygen in the early atmosphere was crucial for the development of life as we know it, as it allowed for the chemical reactions necessary for the formation of organic molecules and the emergence of early life forms.Rate this question:

The age of fossils or dating of fossils can be best estimated by
-
Radioactive carbon (C14) dating method
-
Radioactive nitrogen method
-
Radioactive clock method
-
None of the above
Correct Answer
A. Radioactive carbon (C14) dating methodExplanation
Radioactive carbon (C14) dating method is the best way to estimate the age of fossils. This method is based on the principle that carbon-14 is a radioactive isotope that decays over time. By measuring the amount of carbon-14 remaining in a fossil, scientists can determine how long it has been since the organism died. This method is particularly useful for dating fossils that are less than 50,000 years old. Radioactive nitrogen method and radioactive clock method are not commonly used for dating fossils, making them incorrect options.Rate this question:

The finches of Galapagos islands provide an evidence in favour of
-
Special creation
-
Evolution due to mutation
-
Retrogressive evolution
-
Biogeographical evolution
Correct Answer
A. Biogeographical evolutionExplanation
The finches of the Galapagos islands provide evidence for biogeographical evolution because they have adapted to different environments on different islands, resulting in the development of different beak shapes and sizes. This adaptation is believed to have occurred through natural selection and genetic variation over time, supporting the idea that species can evolve and change in response to their environment.Rate this question:

What is common to whale, seal and shark?
-
Seasonal migration
-
Thick subcutaneous fat
-
Convergent evolution
-
Homeothermy
Correct Answer
A. Convergent evolutionExplanation
Convergent evolution is the process where unrelated species evolve similar traits or characteristics in response to similar environmental pressures. In this case, all three animals (whale, seal, and shark) have evolved similar adaptations for life in the water, such as streamlined bodies, fins, and blubber. This similarity in adaptations is a result of convergent evolution, as these species are not closely related but have independently evolved similar traits to thrive in their aquatic habitats.Rate this question:

When two species of different genealogy come to resemble each other as a result of adaptation, the phenomenon is termed as
-
Divergent evolution
-
Micro-evolution
-
Co-evolution
-
Convergent evolution
Correct Answer
A. Convergent evolutionExplanation
Convergent evolution occurs when two species from different genealogical backgrounds independently evolve similar traits or characteristics due to similar environmental pressures or adaptations. This can result in the species appearing similar in appearance or behavior, even though they are not closely related. This phenomenon is different from divergent evolution, which involves the development of different traits in closely related species, and co-evolution, which refers to the reciprocal evolutionary changes between two or more species.Rate this question:

Thoms of Bougainvillea and tendrils of Cucurbita are examples of
-
Analogous organs
-
Homologous organs
-
Vestigial organs
-
Retrogressive evolution
Correct Answer
A. Homologous organsExplanation
Thorns of Bougainvillea and tendrils of Cucurbita are examples of homologous organs. Homologous organs are those that have a similar structure and origin but may have different functions in different organisms. In this case, both thorns and tendrils are modified structures that have evolved from the same ancestral structure. They may serve different purposes in Bougainvillea and Cucurbita, but their similarity in structure suggests a common evolutionary origin.Rate this question:

Echidna and Ornithorhynchus are the connecting links between
-
Amphibians and aves
-
Mammals and amphibians
-
Reptiles and mammals
-
Reptiles and amphibians
Correct Answer
A. Reptiles and mammalsExplanation
Echidna and Ornithorhynchus, also known as platypus, are unique mammals found in Australia. They possess characteristics that are common to both reptiles and mammals, making them the connecting links between these two groups. These characteristics include laying eggs like reptiles and possessing mammary glands and producing milk like mammals. Therefore, Echidna and Ornithorhynchus serve as evidence of the evolutionary relationship between reptiles and mammals.Rate this question:

Which of the following provides most evident proof of evolution?
-
Fossils
-
Morphology
-
Embryo
-
Vestigial organs
Correct Answer
A. FossilsExplanation
Fossils provide the most evident proof of evolution because they are the preserved remains or traces of ancient organisms. By studying fossils, scientists can observe the changes in species over time, documenting the transition from one form to another. Fossils also provide evidence of extinct species and the development of new species. This tangible evidence supports the theory of evolution and allows scientists to reconstruct the history of life on Earth.Rate this question:

A baby has been born with a small tail. It is the case exhibiting
-
Retrogressive evolution
-
Mutation
-
Atavism
-
Metamorphosis
Correct Answer
A. AtavismExplanation
Atavism refers to the reappearance of a trait that was present in earlier generations but had disappeared in more recent ones. In this case, the baby being born with a small tail is an example of atavism because the trait of having a tail is a characteristic that was present in ancestral species but was lost in humans over time. The reappearance of this trait in the baby suggests a regression to an earlier form, demonstrating atavism.Rate this question:

Which one of the following in birds indicates their reptilian ancestry?
-
Scales on their hind limbs
-
Four-chambered heart
-
Two special chambers crop and gizzards in their digestive tract
-
Egg with a calcareous shell
Correct Answer
A. Egg with a calcareous shellExplanation
The presence of an egg with a calcareous shell in birds indicates their reptilian ancestry. This is because reptiles, like birds, also lay eggs with a hard shell made of calcium carbonate. This similarity suggests a common evolutionary history between birds and reptiles, supporting the idea of reptilian ancestry in birds.Rate this question:

The most apparent change during the evolutionary history of Homo sapiens is traced in
-
Shorting of the jaws
-
Remarkable increase in the brain size
-
Loss of body hair
-
Walking upright
Correct Answer
A. Remarkable increase in the brain sizeExplanation
The most apparent change during the evolutionary history of Homo sapiens is the remarkable increase in brain size. This change is significant because it distinguishes humans from other species and has played a crucial role in our cognitive abilities and development of complex societies. The increase in brain size allowed for the development of advanced thinking, problem-solving skills, language, and cultural advancements. It also led to the expansion of the neocortex, which is responsible for higher cognitive functions such as perception, consciousness, and reasoning. This change in brain size is a defining characteristic of the Homo sapiens species.Rate this question:

-
Stanley Miller
-
Darwin
-
A I Oparin
-
S Fox
Correct Answer
A. A I OparinExplanation
A.I. Oparin is credited with providing the most logical biochemical theory of the origin of life through chemical evolution. Oparin proposed that life on Earth originated from simple organic molecules that formed in the early atmosphere and oceans. He suggested that these molecules underwent a series of chemical reactions, eventually leading to the formation of more complex organic compounds and the emergence of life. Oparin's theory laid the foundation for our understanding of how life could have arisen from non-living matter through natural processes.Rate this question:
