Diagram-based questions in previous years' NEET exams

There have been several diagram-based questions in previous years' NEET exams that have tested students' understanding and interpretation skills. These questions often require students to analyze and interpret the given diagrams or figures, and then answer the related questions. Here are some examples of such questions:

1. Anatomy-based questions:
- Identify the labeled parts of the human heart in the given diagram.
- Study the labeled figure of the respiratory system and answer the questions related to the pathway of air during inhalation and exhalation.
- Interpret the given diagram of the digestive system and identify the parts responsible for the secretion of specific enzymes.

2. Genetics-based questions:
- Analyze the given Punnett square and determine the probability of offspring inheriting a specific trait.
- Examine the diagram illustrating the process of meiosis and identify the stages where genetic recombination occurs.
- Interpret the diagram of a karyotype and identify any chromosomal abnormalities present.

3. Ecology-based questions:
- Study the food web diagram and determine the trophic levels of the different organisms.
- Analyze the given ecosystem diagram and identify the primary producers, consumers, and decomposers.
- Interpret the population pyramid and analyze the age structure of a given population.

4. Physics-based questions:
- Examine the given ray diagram and determine the position and nature of the image formed by a concave mirror.
- Study the circuit diagram and identify the components responsible for controlling the flow of current.
- Analyze the given wave diagram and determine the frequency and wavelength of the wave.

These are just a few examples of the diagram-based questions that have been repeatedly asked in previous years' NEET exams. It is important for students to practice analyzing and interpreting diagrams or figures in order to effectively answer such questions. By understanding the key concepts and principles behind the diagrams, students can improve their chances of scoring well in these types of questions.
