branched alkanes have weaker van der waals forces because of the smaller area of contact between the molecules. so less energy is needed to overcome the intermolecular force. Linear alkanes can line up more closer and therefore have stronger van der waals forces than unbranched alkanes. so just remember that van der waals forces are stronger when there is more area of contact between molecules, and obviously area of contact is smaller in branched molecules compared to linear molecules (when they both have the same molecular formula).

It's because when we observed the boiling point of alkane and branched we find that branched has low boiling point which means vanderwaal force is less. That's all i know May be it is due to the open chain has large area and no. of molecules which would add van der waal force. Hope this would help.

The oxide which shows both acidic and basic nature when reacted with acids and base. Eg Al2O3. Al2O3 + HCl ----> AlCl3 + H2O Al2O3 + NaOH ---->NaAlO2 + H2O In first reaction amphoteric oxide is reacted with acid in which it forms a salt and water. Similarly in second reaction it is reacted with a base in which it forms salt and water.

Oxides of metals which have both acidic as well as basic behaviour are known as amphoteric oxides Example:- Acidic medium :-Al2O3+6HCl---> 2AlCl3+3H2O Basic medium :- Al2CO3+2NaOH---> 2NaAlO2+H2O

Bioassay or biological standardization is a type of scientific experiment typically conducted to measure the effects of a substance on a living organism and is essential in the development of new drugs and in monitoring environmental pollutants. Bioassay is used to detect biological hazards or give a quality assessment of a mixture. Bioassay is often used to monitor water quality and also sewage discharge and its impact on surrounding. It is also used to assess the environmental impact and safety of new technologies and facilities.

The term amphibolic  is used to describe a biochemical pathway that involves both catabolism and anabolism. Catabolism is a degradative phase of metabolism in which large molecules are converted into smaller and simpler molecules, which involves two types of reactions. First, hydrolysis reactions, in which catabolism is the breaking apart of molecules into smaller molecules to release energy.  Examples of catabolic reactions are digestion and cellular respiration, where sugars and fats are broken down for energy.
