You want to study the oxygen binding ability of hemoglobin at ph 7.21 and ph 7.60. you decide to use a phosphate buffer.
a) how would you make up 500 ml of 50 mm phosphate buffer, ph 7.21, starting with 1.00 m h3po4 and either 10.0 m hcl or 10.0 m naoh?
b) how would you make up 500 ml of 50 mm phosphate buffer, ph 7.60, starting from your 50mm phosphate buffer at ph 7.21?

Scenario 5 1) take 10 red and 10 black beans and place them, mixed, on the table. record the starting phenotype # and frequencies (% of your total population) of your starting population in the table provided (generation 0). 2) act as a predator. “capture” as many organisms as you can until you have reduced the population to three organisms. put them aside. at this point, the predators die. 3) the remaining organisms each produce 2 clonal offspring. multiply your organisms accordingly and allow them to mix on the table. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 1). 4) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 2). 5) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 3).

Based on the law of dominance, we would expect percent of the offspring from this cross to have large teeth.

The picture showed normal blood cells which are around and sickle cells which appear much longer people with sickle-cell suffer from the sickle cell anemia which is inherited diseaseit is caused by a change in gene responsible for production of hemo goblin this type of change is known as an
