Problem: Epigenetic changes in eukaryotic biology serve to regulate the process of cellular differentiation. During morphogenesis, totipotent stem cells become the various pluripotent cell lines of the embryo, which in turn become fully differentiated cells. A single fertilized egg cell, the zygote, gives rise to the many different plant cell types including parenchyma, xylem vessel elements, phloem sieve tubes, guard cells of the epidermis, etc. as it continues to divide. The process results from the epigenetic activation of some genes and inhibition of others.
What process causes changes in plant cells?

According to Sahih al-Bukhari, the Quran was recited among Levantines and Iraqis, and discussed by Christians and Jews, before it was standardized. Its language was similar to the Syriac language.[citation needed] The Quran recounts stories of many of the people and events recounted in Jewish and Christian sacred books (Tanakh, Bible) and devotional literature (Apocrypha, Midrash), although it differs in many details. Adam, Enoch, Noah, Eber, Shelah, Abraham, Lot, Ishmael, Isaac, Jacob, Joseph, Job, Jethro, David, Solomon, Elijah, Elisha, Jonah, Aaron, Moses, Zechariah, John the Baptist and Jesus are mentioned in the Quran as prophets of God (see Prophets of Islam). In fact, Moses is mentioned more in the Quran than any other individual. Jesus is mentioned more often in the Quran than Muhammad, while Mary is mentioned in the Quran more than the New Testament. Muslims believe the common elements or resemblances between the Bible and other Jewish and Christian writings and Islamic dispensations is due to their common divine source,[citation needed] and that the original Christian or Jewish texts were authentic divine revelations given to prophets.
What do devout Muslims believe is the reason for no overlap of events and characters in the Bible and Quran?
A: unanswerable

Question: On January 21, 1990, Rukh organized a 300-mile (480 km) human chain between Kiev, Lviv, and Ivano-Frankivsk. Hundreds of thousands joined hands to commemorate the proclamation of Ukrainian independence in 1918 and the reunification of Ukrainian lands one year later (1919 Unification Act). On January 23, 1990, the Ukrainian Greek-Catholic Church held its first synod since its liquidation by the Soviets in 1946 (an act which the gathering declared invalid). On February 9, 1990, the Ukrainian Ministry of Justice officially registered Rukh. However, the registration came too late for Rukh to stand its own candidates for the parliamentary and local elections on March 4. At the 1990 elections of people's deputies to the Supreme Council (Verkhovna Rada), candidates from the Democratic Bloc won landslide victories in western Ukrainian oblasts. A majority of the seats had to hold run-off elections. On March 18, Democratic candidates scored further victories in the run-offs. The Democratic Bloc gained about 90 out of 450 seats in the new parliament.
Is there an answer to this question: What country's independence were the chain members celebrating?

Answer: Ukrainian
