The correct Answer is:
To analyze the statements about evolution, we will evaluate each one step by step. ### Step 1: Evaluate the first statement **Statement:** "Homology is based on convergent evolution whereas analogy refers to a situation exactly opposite." **Analysis:** - Homology refers to structures in different species that share a common ancestry, which is a result of divergent evolution. - Analogy, on the other hand, refers to structures that serve similar functions but do not share a common ancestry, resulting from convergent evolution. - Therefore, the first statement is incorrect because it incorrectly associates homology with convergent evolution. ### Step 2: Evaluate the second statement **Statement:** "Industrial melanism in England is one of the best examples of comparative anatomy." **Analysis:** - Industrial melanism refers to the phenomenon where darker-colored individuals of a species become more common in polluted areas due to natural selection. - This concept is more aligned with natural selection rather than comparative anatomy, which studies the similarities and differences in the anatomy of different species. - Thus, this statement is also incorrect. ### Step 3: Evaluate the third statement **Statement:** "Disturbance in genetic equilibrium in a population indicates that evolution has occurred." **Analysis:** - Genetic equilibrium refers to a state where allele frequencies in a population remain constant over generations, indicating no evolution is occurring (Hardy-Weinberg equilibrium). - A disturbance in this equilibrium suggests changes in allele frequencies, which is a sign that evolutionary processes are at work. - Therefore, this statement is correct. ### Conclusion: - The first statement is false. - The second statement is false. - The third statement is true. Thus, the correct answer is that only the third statement is true. ### Final Answer: The correct evaluation is: - Statement A: False - Statement B: False - Statement C: True

Consider the following three statements and select the correct option stating which one is true (T) and which one is false (F). (i) Oparin of Russia and Haldane of England proposed that the first form of life could have come from pre-existing nonliving organic molecules (e.g, RNA, protein etc.) and that formation of life was preceded by chemical evolution. (ii) Based on observations made during a sea voyage around the world. Charles Darwin concluded that existing living forms share similarities to varying degrees only among themselves. (iii) Evolution by natural selection must have started when cellular forms of life with different metabolic capability originated on Earth.

Read the below Statements about the structure of genetic material and identify the correct ones. I. Adenine and guanine are bases that have a double ring structure , cytosine, thymine and uracil are based with a single ring structure . II. An adenine nucleotide from DNA is the same as an adenine nucleotide from RNA , DNA adenine pairs with uracil and RNA adenine pairs with thymine. III. The base pairing that occurs in a double DNA helix and when RNA is synthesised during transcription follows the rule that a purine pairs with a pyrimidine. IV. The two Polynucleotides on a DNA molecule run in opposite directions so that the double helix formed has two strands that are anti-parallel to each other.
