Question Discussion & Solution

Judge is the head in the court while the Principal is the head in a college.

Explanation:

• Plants that grow in the desert have to withstand long dry spells of summer and extreme weather condition
• Hence their leaves stem and roots get modified to prevent loss of excess water and to store water
• Some common adaptation seen in desert plants are:
• 'they have a long root that goes deep in search of water
• they have reduced or very few leaves
• The stem is modified to store water
• Additionally, leaves may turn into spines to protect from predators

Additional Information

• Desert Oak is a tree that is found in  Australia.
• It is found in the dry and arid regions of Australia
• It grows almost 10 ft tall
• It has very few leaves
• Its roots go very deep in search of water
• This water is stored in the tree trunk. Local people use a thin pipe to drink this water.

• Scientific Name: Allocasuarina decaisneana 

• The suspensions that hand from branches are nothing but modifies leaves in order to reduce water loss

Fawn is young one of deer.

Similarly, Larvae are young one of insect.

Concept:

• Newton's Second Law of motion states that the rate of change of momentum of an object is proportional to the applied force in the direction of the force.
•  \(F = \frac{{dp}}{{dt}} = \frac{d}{{dt}}\left( {mv} \right)\;\left( \because {p = mv} \right)\) 

i.e., Force = ma ⇒ Force (F) ∝ a

Where,

F = the force applied, m = the mass of the body, a = the acceleration produced. p = linear momentum, v = velocity of particle at some instance

Explanation:

Given that;

Mass = 100 kg

Acceleration (a) = 10 m/s2

External force on body (F) = ma = 100 × 10 = 1000 N

The pattern followed here is:

Hence, ‘JGW’ complete the series.
