Which of the following is the correct sequence in the biological method?
Correct answer: B. Observation?hypothesis?deduction?testing of deduction
- A. Observation?hypothesis?law?theory
- B. Observation?hypothesis?deduction?testing of deduction
- C. Hypothesis?observation?deduction?testing of deduction
- D. law?theory?deduction?observation
Explanation
The biological method normally proceeds from observation to a tentative hypothesis, then to deductions or predictions that are tested experimentally. A law or theory is not automatically the next step after every observation, so a is the likely error caused by memorising a simplified hierarchy instead of the testing sequence.

About Concept of Evolution
Evolution is the heritable change in populations over generations, driven by mutation, recombination, natural selection, genetic drift and reproductive isolation. Questions examine variation, adaptation, survival and reproduction, speciation, fossil and anatomical evidence, and the difference between individual acclimatization and evolutionary change in a population.
