The amino acid prolinehas a pk1 of 1.99, pk2 of 10.60. the amino acid serine has pk1 of 2.21 and a of pk2 of 9.15. if these two amino acids bind together by peptide bond creating the peptide sequence pro-ser . what will be the overall charge of this peptide at the physiological ph of 7?
a) overall charge will be neutral
b) overall charge will be neutral on pro and negatively charged on the ser
c) overall charge will be negative
d) overall charge will be positive due to the presence of the peptide bond

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?

the pseudoscience are like beliefs, theories, or like practices that are considered scientific

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
