When an individual receives a blood transfusion, the blood types must be matched appropriately. If the blood types are incorrectly matched, an allergic reaction can occur. These types of reactions are best defined as .

type II hypersensitivity

This is an process in which specific antibodies bind to antigens that causes tissue damage or destruction, and mainly occurs when an individual is given the wrong blood type.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
