Statement I: India possesses a tropical monsoon type of climate across its entire geographical extent uniformly.
Statement II: The presence of the Himalayas prevents the extreme cold winds of northern Asia from affecting the Indian subcontinent.

Q5677. Which of the following is correct regarding the phenomenon of ‘October Heat’?
Explanation
‘October Heat’ refers to the oppressive weather conditions experienced during the retreat of the monsoon. As the rains stop, skies clear and temperatures rise. However, the ground remains moist, leading to high humidity. This combination of high heat and high humidity creates very uncomfortable and sticky conditions for the population, typically occurring during the transition from the rainy to winter season.
Q5678. Which of the following is an exception to the services provided under the Integrated Child Development Services (ICDS) scheme?
Explanation
The Integrated Child Development Services scheme offers a comprehensive package of six services, including supplementary nutrition, immunization, and health check-ups. It also provides non-formal pre-school education to children aged three to six years at Anganwadi centers. However, formal primary school education for classes one to five is not part of ICDS; it is instead covered under the general school system.
Q5679. Identify the correct pair regarding Har Gobind Khorana’s discoveries.
Explanation
Khorana’s work confirmed that the genetic code is read in groups of three nucleotides, known as codons. Each triplet corresponds to a specific amino acid used to build proteins. This discovery was essential for understanding the translation process. While he identified these triplets, AUG is known as the universal start codon, and UAA is one of the standard stop codons.
