Liver is the largest digestive gland of the body which is reddish brown in colour. It is divided into two main lobes, right and left lobes. On the undeside of the liver, the gall bladder is present. It stores the bile which is secreted by the liver. The bile is secreted into the smll intestine when food enters it. Bile helps in the digestion of fats.

Functions of Liver:

• Controls blood sugar and amino acid levels
• Synthesizes foetal red blood cells
• Produces fibrinogen and prothrombin, used for clotting of blood
• Destroys red blood cells
• Stores iron, copper, vitamins A and D.
• Produces heparin (an anticoagulant)
• Excretes toxic and metallic poisons
• Detoxifies substances including drugs and alcohol

Since there are only four bases which code for twenty amino acids, the code should be made up of three bases, i.e., (4 × 4 × 4) = 64 codons; a number more than the required.

If the codon consists of four letters, only (4 × 4), only sixteen codons are possible, which is less than the required. Hence the codon is a triplet. 

As the ribosome moves on mRNA, continuously without break, the codons are read in a contiguous manner.

The small intestine is the longest part of the alimentary canal. 

It comprises of 3 parts – duodenum, jejunum and ileum.

• Duodenum is C-shaped and receives the bile duct (from liver) and pancreatic duct (from pancreas).
• Jejunum is the middle part of the small intestine. It is a short region. It contains the enzymes like sucrase, maltase, lactase and lipase.
• Ileum forms the lower part of the small intestine. It is the longest part of the small intestine. It contains minute finger like projections called villi. Absorption of food takes place here.

Correct answer is D.

Alleles, the abbreviated form of term allelomorphs indicates alternative forms of the same gene.

The process of formation of sperms is called spermatogenesis.

Taking RHS

X + X'Z + YZ

= (X + X') . (X + Z) +YZ (Distribution Law)

= 1.(X + Z) + YZ                        (A + A' = 1)

= X + Z + YZ

= X + Z (1 + Y)

= X + Z             (1 + A =1; 1.A =A)

= Hence Verified

(i)  

Hence, X + 0 = X

(ii)

Hence,X + X' = 1

A + C = A + A 'C + BC

Solve R.H.S

A + A'C + BC

(A + A').(A + C) + BC      (Using distributive law)

1.(A + C) + BC                   [Q.A + = 1]

= A + C + BC

= A + C(1 + B)

= A + C.1 = A + C = L.H.S. (Hence, verified)

(i)   

 (ii)

The boolean expression is :

I=[(A+b).(A’+C’)].(B+C)

When kidneys lose their filtering efficiency, an excessive amounts of fluid and toxic waste accumulate in the body. This condition is known as kidney (renal) failure. For this, an artificial kidney is used to filter the blood of the patient. The patient is said to be put on dialysis and the process of purifying blood by an artificial kidney is called hemodialysis. When renal failure cannot be treated by drug or dialysis, the patients are advised for kidney transplantation
