Answer:
Atoms are the smallest units of matter that still retain the fundamental chemical properties of an element. Much of the study of chemistry, however, involves looking at what happens when atoms combine with other atoms to form compounds. A compound is a distinct group of atoms held together by chemical bonds. Just as the structure of the atom is held together by the electrostatic attraction between the positively charged nucleus and the negatively charged electrons surrounding it, the stability within chemical bonds is also due to electrostatic attractions. To illustrate further, consider the two major types of chemical bonds: covalent bonds and ionic bonds. In covalent bonds, two atoms share pairs of electrons, while in ionic bonds, electrons are fully transferred between two atoms so that ions are formed. Let’s consider both types of bonds in detail.

Answer:
Bronchoconstriction may be defined as the constriction of the lung airways that might occur due to the tightening of the smooth muscle. This might result in the sneezing and coughing.
The anti - inflammatory drugs are taken against the symptoms of the constriction. These drugs causes the relaxation of the airways and also result in the decrease of the airway hyper reactions with the different stimuli that might result in the constriction symptoms.
The dialysis bag will remain the same size in a isotonic solution.
