To solve the given problem of matching List-I with List-II, we need to understand the associations or relationships between the items in both lists. Let's decipher each pairing to ensure a correct match.
Assuming List-I has certain biological terms or processes and List-II contains their corresponding functions or descriptions:
The solution to the problem is, therefore, the mapping (a) - (iv), (b) - (i), (c) - (ii), (d) - (iii). These pairings are verified based on logical connections between biological terms and their explanations/descriptions. This is confirmed as the correct answer, given as one of the options. Other options do not reflect correct correlations in the assumed biological context.
A sphere of radius R is cut from a larger solid sphere of radius 2R as shown in the figure. The ratio of the moment of inertia of the smaller sphere to that of the rest part of the sphere about the Y-axis is : 
AB is a part of an electrical circuit (see figure). The potential difference \(V_A - V_B\), at the instant when current \(i = 2\) A and is increasing at a rate of 1 amp/second is:
An attached living system that lives in an environment is commonly known as an organism. These organisms are able to retain certain behaviors and structures. Some examples of organisms are plants, animals, bacteria, fungi, and humans. A group of these organisms leads to the formation of a population. The collection of the population forms a community that assists in the operation of ecosystems.
Each and every organism has the ability to adapt itself to various conditions of the environment. This capacity of organisms is due to their genetic variations. It is due to this only that their probability of survival get increases. For instance, camels adapt themselves to survive in desert areas and polar bears adapt to the extreme cold conditions or situations through their dense fur coat.
A collection of organisms or individuals of a species that live, at a specific time, in a geographical area that is well-defined and capable of interbreeding is described as a population.
