In the context of environmental science and biology, various types of conservation methods are applied to protect species. One key type is taking threatened species out of their natural habitat and placing them in special settings. This process involves:
Based upon these descriptors, this type of conservation is known as Biodiversity conservation. This approach focuses on maintaining and restoring varied forms of life and ensuring they are conserved ex-situ, that is, outside their natural habitats.
Consider a water tank shown in the figure. It has one wall at \(x = L\) and can be taken to be very wide in the z direction. When filled with a liquid of surface tension \(S\) and density \( \rho \), the liquid surface makes angle \( \theta_0 \) (\( \theta_0 < < 1 \)) with the x-axis at \(x = L\). If \(y(x)\) is the height of the surface then the equation for \(y(x)\) is: (take \(g\) as the acceleration due to gravity) 
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 :
