At a point during a cell's development, it begins to differentiate. How does differentiation occur? A. A developing cell's function is determined by the number of organelles that are contained in the cell. B. Certain genes are turned on and others are turned off; this action produces adult cells that are specialized. C. As a cell matures, genes that are not necessary to its function are ejected out of the cell through active transport. D. The number of chromosomes in the cell is reduced by half; this action triggers the specialization of the cell.

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.

Where does the information about where each transcription factor binds originate?
