Pls help ASAP!! A cell needs to divide because as a cell gets bigger, in interphase (G1), it uses up food and oxygen more quickly, places more demands on its DNA, and has more trouble moving enough materials across the cell and through the cell membrane. The cell then replicates its DNA (S Phase), which means it makes an identical copy of, or SYNTHESIZES, its DNA. The next phase (G2) is preparation for mitosis. Cell Division consists of 2 parts: Mitosis (4 phases that divide the nucleus) and Cytokinesis (the division of cytoplasm and the cell membrane). A cell may enter a resting phase (G0), where it will remain until there is a need for the cell to divide. Cancer cells cannot enter the G0 phase, and therefore repeat the cell cycle continuously.

the answer is b

b. the carbon cycle ensures living things have a source of hydrogen

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
