The <u>Henderson-Hasselbalch equation</u> and pKa can be used to determine the % ionization if it is assumed that the amino and carboxyl groups are not preventing ionization.
- aspartate at ph 5.4 = 98.3%
- glutamate at ph 11.8 = 100%
- histidine at ph 8.0 = 99%
Henderson-Hasselbalch equation- Henderson-Hasselbalch Equation to determine the pH of a solution. Knowing the pH of a solution is particularly significant for many chemical processes as well as for biological systems. The estimated pH value of a buffer solution may be determined using the Henderson-Hasselbalch equation.
pH- A solution's acidity or alkalinity may be determined based on the concentration of hydrogen ions in the solution, or pH. Typically, the pH scale runs from 0 to 14.

I believe <u>B.) Analogous structures show that living in similar habitats doesn't lead to similar adaptations </u>is your right answer.
The ANALOG FORECASTING METHOD is known as the oldest method in the forecasting of weather. This kind of method reviews the previous weather events in order to lead to a particular weather event. Hope this helps.
I just looked it up, it's carbon!
It's false because no one has found out officialy
