For a student to have inherited left handedness from parents who are both right handed, it means that the left-handed trait is recessive in both parents.

The pattern of inheritance of handedness can, thus, said to be simple dominant/recessive with the right handedness trait being dominant while the left handedness is recessive.

Let us assume that right-handedness is represented by the allele A and left-handedness by the allele a.

The two parents are heterozygous, hence, their genotypes each would be Aa.

                Aa   x   Aa

            AA   Aa   Aa   aa

From the cross, 3/4 of their children would be right handed (AA or Aa) while 1/4 would be left handed (aa). The student in question must have been from the 1/4.

bicarbonate ions in blood can absorb hydrogen ions, keeping pH balanced. bicarbonate is acting as a ________  in blood?
Veseljchak [2.6K]
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 are responsible for regulating blood pH: the bicarbonate buffer system, 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 system
