Explanation:The tetrahedral shape is formed by the electrons repulsing one another, which forms the tetrahedron—the shape in which all the electrons are as far away from one another as possible.
Examples include methane (CH4) and ammonium(NH4+).
Methane has a central carbon atom ringed by four hydrogens, which form the "spokes" of the tetrahedral molecule.
Tetrahedral molecules are nonpolar if the four surrounding atoms are the same, in the cases of methane and ammonium, and have a bond angle of 109.5˚.
However, tetrahedral molecules can also be polar if they are like chloroform (CHCl3). The central atom has four electron domains, but they are differently sized.
<span>This is a clear example of anabolism, which is the process of producing complex molecules from much simpler ones. This process needs energy consume, and without it it could not be done. This energy is obtained from catabolic reactions</span>

Over time, the toxins from inhaled cigarette smoke break the thin walls of alveoli, leaving larger, less efficient air sacs. The sacs also begin to lose their bounce, making it harder to bring in the oxygen and expel carbon dioxide. 3 Both can become partially trapped in the lungs.
