Which statement is true?
stomata, when closed, allow co2 to diffuse into plants. stomata are important in terrestrial plants because they allow co2 to diffuse into the plant. stomata are not important in algae because they do not need co2. stomata are important in terrestrial plants because they allow the roots to absorb water and nutrients from the soil.

The 3rd answer that they allow the roots to absorb water & nutrients from the soil.

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.
