A pedigree chart, which is most frequently used to represent people, show dogs, and race horses, depicts the incidence and manifestation of phenotypes of a particular gene or species and its descendants from one generation to the next.
As males have only one X chromosome, the trait must be X-linked for a pedigree chart to indicate only men affected in all generations. The characteristic has to be recessive to make sure that all men are impacted. Males only need one recessive allele, whereas females need two to display this characteristic.

Which bond would you expect to pay a higher interest rate: a bond of the U.S. government or a bond of an Eastern European government? Explain.
Due to a higher risk of default, the bond issued by an eastern European government would typically offer a higher interest rate compared to the bond issued by the U.S. government.
The interest rate on a bond is determined by several factors, including the perceived creditworthiness of the issuer. If an eastern European government is considered to have a higher risk of defaulting on its debt obligations than the U.S. government, investors would demand a higher interest rate to compensate for the increased risk.
This is because default risk reflects the likelihood of an issuer not being able to make payments on its debt, which would result in losses for bondholders. Therefore, an investor would require a higher return on investment to hold a bond from an eastern European government compared to the U.S. government to offset the higher risk.

According to the pH scale, as the pH value increases, the level of acidity decreases, and the level of basicity increases.
Titration curve: plotting a graph of pH vs burette
reading of WASB & SASB.
from graph:
1) Equivalence point of WASB volume = 7.90 ML
pH = pKa=at ½ of equivalence volume
pKa= pH at (7.90/2) 3.95 mL = 5.20
2) Equivalence point of SASB volume = 8.47 mL
Therefore, pH = pKa at ½ equivalence = ½x8.47=4,24 mL
pka = pH at 4.24 mL = 5.00
PHol WASB = 5.20 & pH of SASB=5.00
From pH, we can say that pH of SASB is slightly acidic than pH of WASB (slightly basic)
pH of SASB = slightly acidic (5.0)
pH WASB = slightly basic (5.2)
Therefore, acididity decreases as value of pH increases & basicity increases as pH value increases according to pH scale
