Answer:
Hydrogen bonding is caused by the tendency of some atoms in molecules to attract electrons more than their accompanying atom. This gives the molecule a permanent dipole moment – it makes it polar – so it acts like a magnet and attracts the opposite end of other polar molecules.
The resulting two cells will have an identical genetic composition.
Answer:
hydrogen bond
Explanation:
by weak electrical attraction between two polar molecule hydrogen bond is developed between them
the example is water molecule in case of water two water molecules are attracted toward each other by strong hydrogen bond which is developed between highly electronegative oxygen of one water and electropositive hydrogen of another water molecule
Answer:
The main function of the lungs is the process of gas exchange called respiration (or breathing). In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood. A reduced lung function means that the ability of lungs to exchange gases is reduced.
