Bile does not contain any enzyme but it is essendal for digestion because bile is alkaline and contain salts which helps to emulsify the fat present in the food. So, the bile perform two functions:

  1. The food coming from the stomach is acidic and has to be made alkaline for the pancreatic enzymes to act.
  2. The bile salts breakdown the fat present in the food into smaller globules. This increases the efficiency of enzymes in the small intestine to digest the food effectively.

x2-5x+k

 Here, a=1, b=-5 and c=k 

Now, α+ β = -b/a= -(-5)/1= 5 

α*β  = c/a= k/7= k

 Now,α - β =1

 Squaring both sides, we get,

 (α - β)2=12 

⇒ α2 + β2 - 2αβ = 1

⇒ (α2 + β2 + 2αβ) - 4αβ = 1

⇒ (α +β)2 -4αβ =1

⇒ (5)2-4k=1

⇒ -4k= 7-25

 ⇒ -4k= -24 

⇒ k=6 So the value of k is 6.

Stomach also contains gastric glands which secrete gastric juices.These juices are pepsin,HCl and mucus.Pepsin helps to break down proteins into pepteoses and peptides.HCl makes the medium acidic,this is helpful as pepsin gets activated in acidic medium.Mucus protects the inner wall of stomach and prevents the acid to damage it.

The major role of the stomach in digestion is to churn the food properly coming from the esophagus so that small intestine can absorb the molecules. In the stomach, food and water are mixed properly to form a slurry known as chyme. After this process, the food is ready to move into the small intestine. The liver, gall bladder, and pancreas are known as the alimentary system of humans and together help in the process of digestion.

The following instances gave rise to civil war in Sri Lanka:

  • After Sri Lanka gaining independence in 1948, the Sinhala community leaders, on the basis of majority, sought to secure dominance over the government.
  • This resulted in establishment of Sinhala supremacy by adopting a series of majoritarian measures.
  • In 1956, an Act passed Sinhala as the only recognised official language of the country.
  • The government favoured the Sinhala applicants in education, jobs and in many fields.
  • Also, the government stipulated that people should foster and protect Buddhism.
  • The Tamils were denied equal political rights and their interests were ignored.
  • As a result, the relations between the Sinhala and the Tamils communities got strained over time.

All these reasons made the Tamils feel discriminated and lead to distrust between the communities.

The main components of the transport system in human beings are the heart, blood, and blood vessels.
a. Heart pumps oxygenated blood throughout the body. It receives deoxygenated blood from the various body parts and sends this impure blood to the lungs for oxygenation.
b. Blood helps in the transport of oxygen, nutrients, CO2, and nitrogenous wastes.
c. The blood vessels (arteries, veins, and capillaries) carry blood either away from the heart to various organs or from various organs back to the heart.
