Solution:
Ionic hydrides are compounds form between hydrogen and the most active metals, especially with the alkali and alkaline-earth metals of group one and two elements.

Covalent hydrides are formed when hydrogen reacts group 13 to group 17 elements. All the group 13 elements form electron deficient compounds with hydrogen. All group 14 elements form electron precise compounds. Elements from groups 15 through 17 form such bonds that have excess electrons which are present as lone pairs.

(a) MgH2 is an ionic compound.

(b) GeH4 has sufficient number of electrons required for forming covalent bonds, so it is electron precise compound.

(c) B2H6 is electron deficient compound as it has incomplete octet.

The correct answer is:

Solution:
Mechanism	Definition and Examples

Adaptive radiation	The process of evolution of different species in a given geographical area starting from a point and literally radiating to other areas of geography (habitats) is called adaptive radiation. Example: Darwin finches

Divergent evolution	The structures in different organisms which have similarities in their anatomy or basic plan but serve different functions are known as homologous structures. This is an example of divergent evolution. Example: Bones of forelimbs in man and whale

Convergent evolution	The structures in different organisms which are not similar anatomically though they perform similar functions are called analogous organs. This is an example of convergent evolution. Example: Wings of butterfly and bird

Evolution by anthropogenic action	Herbicide and pesticide resistance developed in the weeds and pests respectively after prolonged use of herbicides and pesticides. This is also an example of natural selection which supports the process of evolution due to anthropogenic action or due to actions of man.

The correct answer is:
(a)−(iv);(b)−(i);(c)−(ii);(d)−(iii)

Solution:
Adaptation	Example

Allen's rule	Mammals from colder climates generally have shorter ears and limbs (extremities) to minimize heat loss. Example: Polar seal

Physiological adaptation	Kangaroo rat is capable of meeting all of its water requirements through its internal fat oxidation where water is released as a by-product. It can also concentrate its urine so that a minimal volume of water is used to remove excretory products. Thus, it is an example of physiological adaptation.

Behavioural adaptation	Desert lizards lack the physiological ability to cope with extreme temperatures but manage the body temperature by behavioural means.

Biochemical adaptation	A large variety of marine invertebrates and fishes are adapted biochemically to survive great depths in the ocean where the pressure (called crushing pressure) could be >100 times the normal atmospheric pressure.

Solution:
$\begin{array}{|l|l|}
\hline \begin{array}{l}
\text{Cartilaginous} \\
\text{Joint}
\end{array} & \begin{array}{l}
\text{- This is a type of amphiarthrosis or imperfectly movable joint.} \\
\text{- Between adjacent vertebrae in vertebral column such joints are} \\
\text{present. This allows little movement.}
\end{array} \\
\hline \begin{array}{l}
\text{Ball and} \\
\text{Socket Joint}
\end{array} & \begin{array}{l}
\text{- This is a synovial joint.} \\
\text{- This allows complete movement of the bones articulating.} \\
\text{- Between Humerus and Pectoral girdle such joint is found.} \\
\text{This joint allows multi-axial movement.}
\end{array} \\
\hline \text{Fibrous Joint} & \begin{array}{l}
\text{- They are non-movable joints.} \\
\text{- They are found between flat skull bones.}
\end{array} \\
\hline \text{Saddle Joint} & \begin{array}{l}
\text{- This is also a type of synovial joint.} \\
\text{- This is found in between carpal and metacarpal of thumb.}
