B.

Explanation:

Which of the following describes the outer core?

A. The solid, rocky layer on the outside

B. A layer of liquid metal that spins

C. A dense layer of solid metal

D. Hot, partially melted rock that flows

Because the outer core is the third layer of the Earth. It is the only liquid layer, of metals irons and nickel Also its responsible  for Earths  magnetic field as earth spins on its Axis the substances move  also move around during that

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.
