False. The statement "Last dinosaur disappeared approximately 5 crores years ago" is incorrect. Dinosaurs went extinct around 65 million years ago, not 5 crores (which is equivalent to 50 million) years ago. False. There is no Nobel Prize awarded specifically for the invention and publication of the Journal Radio Carbon. Additionally, "Dr Har Govind Kherane" is not a known recipient of a Nobel Prize.
RNA polymerase is used for the synthesis of mRNA (messenger RNA), so the statement is true.
Living organisms can produce new individuals like themselves due to genes, but there are other factors involved as well. So the statement is partially true.
The theory of natural selection, which mentions the "survival of the fittest," is attributed to Charles Darwin, not "Lanark." So the statement is false.
False. Sickle-cell anemia is caused by a genetic mutation, not crossing-over.
Changes acquired during life cannot be transferred to the next generation according to the principles of genetics. So the statement is false.
The formation of the first living material on Earth is still a subject of scientific research and debate. So the statement is uncertain.
False. The duration of all gradual changes that occurred over time spans much longer than 300 crore years (3 billion years).
False. The appendix is considered a vestigial organ in humans, meaning it has lost its original function. It may have had a role in digestion in early human ancestors, but it is not useful or functionally significant in modern humans. However, it does serve important functions in ruminant animals.
False. The Mesozoic era was not dominated by varieties of human beings. Humans did not exist during the Mesozoic era. Instead, it was the era of the dinosaurs and other prehistoric reptiles.
False. C-12 is a stable isotope of carbon and does not decay. It is commonly found in living organisms and does not undergo radioactive decay.
True. The Paleozoic era was characterized by the dominance of invertebrates, as well as the emergence of reptiles, amphibians, and fish (pisces).
