Calculate the pH of a 1 L solution containing 0.100 M formic acid and 0.100 M sodium formate before and after the addition of 1.00 mL of 5.00 M NaOH. How much would the pH change if the NaOH were added to 1.00 L of pure water? (pKa for formic acid is 3.75)

#Unit 5. Developmental Biology

Programmed cell death, or apoptosis, is an essential part of animal development. In the nematode, with its invariant cell lineage, particular cell lineages or particular cells within specific lineages are destined to end in programmed cell death, and it was this feature that allowed the identification of the process and the analysis of its genetic control.
