4. Ans: If we add sugar or any solute to a solution it will affect its colligative properties which are properties of solutions that depend upon the ratio of the number of solute particles to the number of solvent molecules in a solution. So after addition the boiling temperature will increase whereas freezing temperature will decrease.
5. Ans: DNA strand A has higher temperature to melt than strand B, because nucleotide pair ‘A-T’ has a weaker bond than the nucleotide pair ‘G-C’.
6. Ans: From the m-RNA with given code AAAAAAAAA will produce the protein with Lys (Lysine) amino acid.. Lys-Lys-Lys.
7. Ans: Type II DM (non-insulin dependent) is a metabolic disorder characterized by increased blood glucose level Type II diabetes is where insulin is produced by beta cells of langerhans (Pancreatic cell) but it is not properly utilized by cells, so insulin shot can’t be effective. Anti-dabetic drugs can be used such as tolbutamide, metformin.
8. Ans: Ethylmethyl propyl ether does not exist because normally ether are the alkylated derivative of alcohol. Thus it can have two alkyl group attached at two ends. So ethers can be dimethyl ether, diethyl ether, ethyl methyl ether, ethyl propyl ether. (oxygen is sp3 hybridized)...
