Discrepancies in Allen Answer Key and NTA NEET 2020 Solutions: Insights into Chemistry and Biology

The National Testing Agency (NTA) NEET 2020 examination is a significant milestone for medical aspirants in India. It's governed by a set of strict standards and marked by various answer keys released by different coaching centers. Two prominent such centers, Allen and Aakash, have differing answers to certain questions, which has led to considerable discussion among students and educators. This article aims to clarify these discrepancies, particularly in chemistry and biology, drawing from the questions marked as differing in both answer keys.

Chemistry Questions with Discrepancies

In the realm of chemistry, two specific questions show a difference in the answers provided by the Allen and Aakash answer keys.

Question 1: Effect of Increasing Reactant Concentration

Aakash Answer Key: The effect of increasing the reactant concentration is the heat of reaction.

Allen Answer Key: The effect of increasing the reactant concentration is collision frequency.

Analysis: According to Allen and Aakash, the difference in answers primarily revolves around the kinetic explanation of increasing reactant concentration. While Aakash attributes the effect to an increase in the heat of reaction, Allen points towards an increase in the collision frequency between the reactant molecules. The key point here is the kinetic theory of molecules and the two possible ways to describe the behavior.

Biology Questions with Discrepancies

The discrepancies are not limited to chemistry alone and extend into biology as well. Particularly, two questions on the cell cycle (G0 phase) differ in the answers provided by the two answer keys.

Question 2: G0 Phase of the Cell Cycle

Aakash Answer Key: The correct answer for the G0 phase is M phase.

Allen Answer Key: The correct answer for the G0 phase is both G1 and M phase.

Analysis: In Aakash's key, the G0 phase is described as occurring during the M phase, suggesting a direct correlation with the mitotic phase. However, in Allen's key, the G0 phase is recognized as a distinct phase that includes components of the G1 phase and M phase. This differentiation reflects the nuanced understanding and interpretation of the cell cycle by each center.

Implications for NEET Aspirants

The differences in the answer keys by Allen and Aakash indicate varying approaches to teaching and explaining concepts. For NEET aspirants, it is crucial to consolidate their knowledge across multiple resources to ensure a well-rounded understanding. It's essential to consult the official NTA NEET keys whenever available and use these differences as a learning opportunity rather than a source of stress.

Conclusion

The discrepancies between the Allen and Aakash answer keys for NEET 2020 are a testament to the complexity of concepts like the cell cycle and the kinetic behavior of molecules. These differences highlight the importance of multi-angle learning and the need to cross-reference with official resources. Aspirants should leverage these insights to enhance their preparation and gain a thorough understanding of the subject matter.
