   • Biological names are generally in Latin and written in italics.

   • The first word in a biological name represents the genus.

   • Both words in a biological name, when handwritten, are underlined to indicate their vernacular origin.

   • The first word denoting the genus starts with a capital letter.
     (Correct answer: The underlining is not for vernacular origin, but to denote Latin names)

   (1) The exact definition of species is still controversial
   (2) The mechanisms of speciation are not known
   (Correct answer: 1)

10. Describe the mechanism of countercurrent exchange in the nephron and its significance in urine concentration.

Tips for NEET Preparation

• Focus on NCERT textbooks, as many questions are directly based on them, especially in Biology.

• Practice previous years’ question papers and mock tests to understand the exam pattern and frequently asked concepts.

• Pay attention to “trap words” in questions such as always, only, never, except.

• Strengthen your understanding of high-yield topics: Human Physiology, Genetics, Ecology (Biology); Mechanics, Optics, Modern Physics (Physics); Organic and Inorganic Chemistry, Thermodynamics (Chemistry).

Practicing these types of questions and mastering core concepts will help you perform well in the NEET exam.

The NEET (National Eligibility cum Entrance Test) is a highly competitive exam for medical aspirants in India, testing knowledge in Physics, Chemistry, and Biology (Botany and Zoology). Below is a curated list of 10 important types of questions, covering key concepts frequently tested in NEET, based on trends and patterns from previous years. These are not specific questions but rather representative question types with examples, as providing exact questions requires access to copyrighted material or specific papers. Each question type is aligned with the NEET 2025 syllabus and reflects high-yield topics.

Physics

1. Mechanics – Projectile Motion
   Example: A projectile is launched at an angle of 30° with a velocity of 20 m/s. Calculate the maximum height reached.
   Why important: Projectile motion is a recurring topic in NEET, testing concepts like kinematic equations and energy conservation. Focus on resolving vectors and applying formulas like h=u2sin⁡2θ2g h = \frac{u^2 \sin^2\theta}{2g} h=2gu2sin2θ​.
2. Electrodynamics – Electric Field and Potential
   Example: What is the electric potential at a point 2 m away from a charge of 5 μC?
   Why important: Questions on electric fields, potential, and capacitance appear frequently. Understand formulas like V=kqr V = \frac{kq}{r} V=rkq​ and practice numericals involving point charges.
3. Optics – Ray Optics
   Example: A convex lens has a focal length of 20 cm. If an object is placed 30 cm from the lens, find the image distance.
   Why important: Ray optics (lenses, mirrors) is a high-weightage topic. Master the lens formula (1f=1v−1u \frac{1}{f} = \frac{1}{v} – \frac{1}{u} f1​=v1​−u1​) and sign conventions.

Chemistry

4. Physical Chemistry – Chemical Equilibrium
   Example: For the reaction N2+3H2↔2NH3 N_2 + 3H_2 \leftrightarrow 2NH_3 N2​+3H2​↔2NH3​, calculate the equilibrium constant if the concentrations are given.
   Why important: Equilibrium questions, including Le Chatelier’s principle, are common. Focus on Kc K_c Kc​, Kp K_p Kp​, and their relationship (Kp=Kc(RT)Δn K_p = K_c (RT)^{\Delta n} Kp​=Kc​(RT)Δn).
5. Organic Chemistry – Name Reactions
   Example: Identify the product of the reaction when benzene undergoes nitration.
   Why important: Organic chemistry emphasizes reactions like nitration, halogenation, and aldol condensation. Memorize key name reactions and their mechanisms.
6. Inorganic Chemistry – Coordination Compounds
   Example: What is the oxidation state and coordination number of the central metal in [Co(NH3)6]Cl3 [Co(NH_3)_6]Cl_3 [Co(NH3​)6​]Cl3​?
   Why important: Coordination chemistry is a favorite NEET topic. Practice nomenclature, isomerism, and crystal field theory.

Biology

7. Genetics – Mendelian Inheritance
   Example: In a monohybrid cross between two heterozygous tall plants (Tt), what is the phenotypic ratio of the offspring?
   Why important: Genetics questions, especially Punnett squares and inheritance patterns, are heavily tested. Understand dominant-recessive traits and ratios (e.g., 3:1 for monohybrid).
8. Human Physiology – Respiratory System
   Example: Which of the following statements is true about the role of hemoglobin in oxygen transport?
   Why important: Physiology, especially respiration and circulation, is high-yield. Focus on oxygen dissociation curves and Bohr’s effect.
9. Plant Physiology – Photosynthesis
   Example: Which molecule is the final electron acceptor in the light-dependent reactions of photosynthesis?
   Why important: Photosynthesis and plant physiology are NEET staples. Study light and dark reactions, including the roles of NADP+ and ATP.
10. Ecology – Ecosystem Dynamics
    Example: In a food chain, what percentage of energy is transferred from one trophic level to the next?
    Why important: Ecology questions on energy flow (10% rule) and biogeochemical cycles are common. Understand pyramids of energy and biomass.

Tips for Preparation

• Practice NCERT-based questions: NEET heavily relies on NCERT textbooks, so prioritize them.
• Solve previous year papers: Analyze trends using past papers available from sources like SelfStudys or Shiksha.
• Use free resources: Download chapter-wise important questions from Vedantu or Educart for targeted practice.
• Focus on assertion-reason and diagram-based questions: These are increasingly common in NEET.
