Buffer is an aqueous solution that resists changes in pH when acids or
bases are added to it. A buffer solution is typically composed of a weak
acid and its conjugate base. There are three major buffer systems that

the phosphate buffer system, and the plasma protein buffer system. Of
the three buffer systems, the bicarbonate buffer system is arguably the
most important as it is the only one that is coupled to the respiratory

<span>Parents can pass on chromosomes to their children that are different than their own when the new gene combinations are created by crossing over. The exchange of genetic material between homologous chromosomes is known as crossing over which occurs in meiosis. When homologous chromosomes pair up and exchange different segments of the genetic material. As the result, a new combination of genes will be formed. If there was not crossing over, all genes on a chromosome would be inherited together.</span>
