How is the cell wall different from the cell membrane in plants ? Please help ASAP A)The cell wall is composed of cellulose which makes it thicker and more rigid than the cell membrane .

B)The is composed of , which make it thinner and more flexible than the cell membrane .

C)The cell wall is composed of cellulose , which makes it impermeable to all materials , while the cell membrane is semipermeable

D)The cell waff is composed of lipids , which make it impermeable to all materials , while the cell membrane is semipermeable .

the answer for this question would be d. glaciers

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.
