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.
In meiosis, the chromosome count is reduced from diploid to haploid; the union of two haploid gametes in fertilization restores the diploid chromosome count. Dog sperm contain 39 chromosomes. What are the haploid number and diploid number for dogs. Haploid number (n) is 39; diploid number is (2n) is 78. What process (meiosis or mitosis) is more directly involved in the production of gametes in animals? In plants and most fungi.
