Chromosome number provides no reference for establishing any relationship between organisms. The number of chromosome cannot depict whether a living species belong to plant kingdom or animal kingdom. It cannot even depict the evolutionary history of any species. Thus, the organism with lesser chromosome has not necessarily evolved from the species having larger number of chromosome or vice versa.
Chromosome number can only depict the quantity of genetic material with in an organism and hence no relationship can be established living species only on the basis of chromosome number.
A hydrogen bond is a form of the electrostatic force of attraction which takes place between the hydrogen atom and a more electronegative atom such as nitrogen, fluorine, and oxygen.
Hydrogen bond falls in the category of weak forces.
In size-exclusion chromatography, the type of interaction that takes place between the proteins and dextran is hydrogen bonding.
The hydrogen bonding is possible because dextran, being a polysaccharide of glucose has several hydroxyl groups and thus, they get involved in the hydrogen bonding.
The correct answer is option A. Carrying the genetic code and determining an organism's structure and function are the functions of DNA. It is the hereditary material in almost all other organisms. The information in a DNA is stored as codes that is composed of chemical bases.
Electromagnet is an electrical component that when powered emits a magnetic field based on the amount of current provided. this is the same principal that runs induction motors
