66\(\degree\) North and South
22\(\bigg(\frac{1}{2}\bigg)\degree\) North and South
40\(\degree\) North and South
42\(\bigg(\frac{1}{2}\bigg)\degree\) North and South
The latitude at which heat gain through insolation approximately equals heat loss through terrestrial radiation is at 66\(\degree\) North and South.
At these latitudes, near the poles, there is a balance between the heat received from the Sun (insolation) during the day and the heat radiated away from the Earth's surface during the night, resulting in a relatively stable temperature regime. This is one of the factors contributing to the formation of the polar climates.
So, the correct option is (A): 66\(\degree\) North and South
A biologist surveyed islands of different sizes and consolidated the results in the form of the data given below. Study the data carefully and answer the questions that follow.
Based on data (Birds decline, Plants % decline, Area decline), interpret two reasons for change in the population of migratory birds. 
Given below are two statements:
Statement I: Transfer RNAs and ribosomal RNA do not interact with mRNA.
Statement II: RNA interference (RNAi) takes place in all eukaryotic organisms as a method of cellular defence.
In the light of the above statements, choose the most appropriate answer from the options given below:
The protection, preservation, and management of ecosystems and natural habitats refers to biodiversity conservation and ensuring that they are healthy and functional.
The protection, upliftment, and scientific management of biodiversity refer to the conservation of biodiversity so as to maintain it at its threshold level and derive sustainable benefits for the present and future generation.
The following are the three main objectives of Biodiversity Conservation-
