The major organs of respiratory system in human beings are: (i) Nose (ii) Nasal Passage (iii) Trachea (iv) Bronchi (v) Lungs and (vi) diaphragm.
In human beings, air is taken into the body through the nostrils, is filtered by fine hairs that line the passage. When air passes through the nasal passage, the dust particles and other impurities present in it are trapped by nasal hair and mucus so that clean air goes into the lungs. From here, the air passes through the throat and into the lungs. Trachea does not collapse even when there is no air in it because it is supported by rings of soft bones called cartilage.
Within the lungs, the passage divides into smaller and smaller tubes which finally terminate in balloon-like structures which are called alveoli. The alveoli provide a surface where the exchange of gases can take place. The walls of the alveoli contain an extensive network of blood-vessels. When we breathe in, the ribs are lift up and the diaphragm flattens which increases the size of the chest cavity. Because of this, air is sucked into the lungs and fills the expanded alveoli. The blood brings carbon dioxide from the rest of the body for release into the alveoli, and the oxygen in the alveolar air is taken up by blood in the alveolar blood vessels to be transported to all the cells in the body. During the breathing cycle, when air is taken in and let out, the lungs always contain a residual volume of air so that there is sufficient time for oxygen to be absorbed and for the carbon dioxide to be released.

Calcium chloride is strongly hygroscopic (absorbs water from its surroundings), so it removes moisture from the air, making it dryer. This results in water in the substance to be dried to evaporate into the drier air, and this cycle repeats until the system reaches an equilibrium. Anhydrous calcium chloride is an inorganic salt that easily forms hydrates which promotes its use for removing water from any organic solution.

:63x²y²-7
= 7(9x2y2- 1)
= 7 [(3xy)2 - (1)2]
= 7(3xy - 1)(3xy+1)

Many forests which supplied valuable timber were declared as reserved forests by the British. The tribals were not allowed to collect wood, fruits, hunt and practice shifting cultivation in these forests. This resulted in the loss of livelihood, poverty and hunger among the tribals. The new Forest Act prevented the hunters and forest dwellers to use the trees and forests for their everyday uses that included the fuel, leaves, fodder, grazing of cattle, cutting down wood for housing and fires, collecting roots and fruits etc. Hunting and fishing were banned and they became illegal.

Let the original speed y km/ hr and total time taken be x h
Distance = xy
[ Distance = time × speed]
(y + ½) (x - 1) = xy
xy - y + x/2 - ½ = xy
x/2 - y = ½ ………………(1)
[Distance covered in each case is same]
(y -1) (x + 3) = xy
xy + 3y -x -3 = xy
-x + 3y = 3……………..(2)
Multiply equation 1 by 3 ,
3x/2 - 3y = 3/2…………(3)
On adding eq 2 and 3,
-x + 3y = 3
3x/2 - 3y = 3/2
---------------------
-x +3x/2 = 3/2 +3
(-2x + 3x)/2 = (3+6)/2
x/2 = 9/2
x = 9
On Putting x = 9 in eq 2
-x + 3y = 3
-9 + 3y = 3
3y = 3 +9
3y = 12
y = 12/3
y = 4
Distance covered by man = xy = 9 × 4 = 36 km
Original speed of walking = y = 4 km/h
Hence, the Distance covered by man is 36 km & Original speed of walking is 4 km/h.

a2 - b2 = (a-b)(a +b)
36(a+b)²-49(a-b)²
= [6(a+b)]²-[7(a-b)]²
= [ 6(a + b) - 7(a-b) ] [ 6(a + b)+ 7(a-b) ]
