Which would increase the speed of a sound wave? check all that apply. a wave passes from a solid to a liquid while remaining the same temperature. the medium increases in temperature while remaining in the same phase. the medium decreases in temperature while remaining in the same phase. a wave passes from a gas to a liquid while remaining the same temperature. a wave passes from a liquid to a gas while remaining the same temperature.

Correct options are;

B. The medium increases in temperature while remaining in the same phase.

D. A wave passes from a gas to a liquid while remaining the same     temperature.

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.
