A buffer solution is one which resists changes in pH when small quantities of an acid or an alkali are added to it. Acidic buffer solutions. An acidic buffer solution is simply one which has a pH less than 7. Acidic buffer solutions are commonly made from a weak acid and one of its salts-often a sodium salt. A common example would be a mixture of ethanoic acid and sodium ethanoate in solution. In this case, if the solution contained equal molar concentrations of both the acid and the salt, it would have a pH of 4.76.
They are haploid cells, because  they have half the number of chromosomes as an organism. During  fertilization the diploid number is restored. Sperm are single  cells. 3 people found this useful.
On the other hand, sperm cells are the complete opposite of egg cells. Maybe, thatâs where we get the male are opposites of females from. The sperm is one of the smallest cells in the male body. They are a made up of a small nucleus with a small amount of cytoplasm, some mitochondria and a long tail. They have a straight shape, compared to the round one of the egg cell. A sperm cell consists of a head, a mid-piece and a tail.
