20166.	Question : Biological classification is a dynamic and ever evolving phenomenon which keeps changing with our understanding of life forms. Justify, the statement taking any two examples.
Answer» Solution :Biological classification keeps CHANGING with our understanding of life forms. Initially, new characters were taken by Aristotle, Theophrastus, John Ray and Linnaeus. Linnaeus divided plants on the basis of sex organs only. As more and more KNOWLEDGE gathered for DELIMITATION of taxa, the ways for natural system of classification became clear. This can be understood by following examples : (i) Two kingdom classification was REPLACED by three kingdom classification when Haeckal (1866) proposed the kingdom of protista. (ii) It was converted into FOUR kingdom classification by copeland when he proposed the Kingdom - Monera. (iii) Whittaker in 1969 proposed five kingdom classification. (iv) As the information about biochemistry of archaebacteria gathered, woese raised another kingdom, Archaea.

Discussion

20167.	Question : Biological classification is a dynamic and ever evolving phenomenon which keeps changing with our understanding of life forms. Justify, the statement taking any two examples . Discuss the changes made in studying biological classification from time to time and also enumerate the need for this changes.
Answer» Solution :Biological CLASSIFICATION is undergoing changes. In the beginning, only few characters were picked up arbitrarily in artificial system of classification. Gradually, more characters were used fro classification . Two kingdom system of classification was revised to three kingdom system of classification . In this kingdom protista was added. It was followed by four kingdom system by Copeland (1955) . Kingdom monera was added in TI. FIVE kingdom system of classification (Whittaker, 1963) CAME into force. Woese has added ANOTHER kingdom called Archaea.

Discussion

20189.	Question : Bile juice contains no digestive enzymes , yet it is important for digestion. Why ?
Answer» Solution : Liver does not secrete digestive enzymes. It contains bile pigments BILIRUBIN and biliverdin which are the break down products of HAEMOGLOBIN of dead RBCs, bile salts, cholesterol and phospholipids. Bile helps in emulsification of FATS Bile salts reduce the SURFACE tension of fat droplets and break them into small globules. Bile also activates lipase to digest LIPIDS.

Discussion

20190.	Question : Bile juice contains no digestive enzymes. Yet it is important for digestion. Why ?
Answer» Solution :Inorganic salts present in bile juice remove the acidity of chyme. Enzymes of pancreatic juice become ACTIVE in alkaline medium and perform DIGESTION. Organic salts present in bile juice convert FAT globules into small globules by emulsification makes digestion easy. Thus not CONTAINING digestive enzyme STILL it is important.

Discussion

20191.	Question : Bile juice contains no digestive enzymes yet it is imoportant for digestion.Why?
