A species may become prone to extinction due to which probable characteristics ?

Which one of the following has not changed for the last several thousand years?

The species or taxa which are in danger of extinction and whose survival is unlikely if the causal factors continue to be operating, such a species or taxa will belong to which of the category ?

Changes in land use policy have endangered reptiles and amphibians. Identify those species with the help by interviewing and environment list. Explain how biosphere reserve can make conservation efforts successful.

A large number of oxides can be formed with O^(2-) species but not with O^(-) species-explain. [Given, Delta_(eg)H_(OtoO-)=-141kJcdotmol^(-1) ,Delta_(eg)H_(OtoO^(2-))=702kJcdotmol^(-1) ]

The colour of high yieldding mexican wheats were not liked by the indian. It was originally red grained. Their cultivation was adopted in india on large scale only when exposure to gamma radiations converted them to amber grained. Which of following methods of plant breeding has been put into practise in the given case?

Study the following carefully and explain why mutation (A) did not cause any sickle cell anemia in spite of change in the molecular structure of the gene which codes for Haemoglobin, when as a similar mutation (B) did. (The question is based on properties of the genetic code. c= codon, a = amino acid, Hb = Haemoglobin) Codons for Hb: C_1 - C_2 -C_3 -C_4 - C_5 -G AA -GAA- C_8 ... Amino acids in Hb : a_1-a_2-a_3-a_4-a_5 - Glutamic acid- Glutamic acid - a_8 ...... (Normal Haemoglobin ) Mutation (A) : C_1 -C_2 - C_3 -C_4 -C_5-GAG-"GAA"-C_8...... a_1-a_2 - a_3-a_4-a_5 -Glutamic acid -Glutamic acid - a_8 .... (Normal Haemoglobin ) Mutation (B) : C_1 -C_2 - C_3 -C_4 -C_5-GAG-"GAA"-C_8...... a_1-a_2 - a_3-a_4-a_5 -Valine-Glutamic acid - a_8 .... (Sickle cell Haemoglobin )
