The buffer resists the changes of the pH in a solution by converting a strong acid to a weak acid or a strong base to a weak base. Physiological as well as chemical buffer systems regulate the stabilization and maintenance of the body pH. Chemical buffer systems: A substance which binds to hydrogen ions and removes them from a solution when the concentration of hydrogen ions begins to increase, or a substance which releases hydrogen ions to the solution when the concentration of hydrogen ions begins to decrease is a chemical buffer. Within a second, the normal pH of the solution is restored by the chemical buffers. The chemical buffer systems are classified into three types, namely the bicarbonate, the phosphate, and the protein systems.

Humans consider themselves amazingly clever and innovative, constantly developing "new" ways of altering the world around us. As material consumption has increased, many have turned to the ideas of recycling and reuse as a means to minimize some negative aspects of our modern consumerism. Mother Nature though is the ultimate innovator and, more importantly, the ultimate recycler.

H gene assorts independently from the I gene. Both on autosomes. One man and one woman, both of HhIAIB genotype. Determine the blood type of progeny and fractions out of 16

Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible. Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…
