What is the name for wegener's theory that describes how all of the continents used to belong to one landmass but randomly moved over time?
a.) the theory of coastline similarities
b.)the theory of continental drift
c.)the theory of contraction
d.)the theory of natural selection

The right option is; B.)The theory of continental drift

The theory of continental drift is the theory of Wegener that describes how all of the continents used to belong to one landmass but randomly moved over time.  

The theory of continental drift was set forth by Alfred Wegener; a geophysicist and meteorologist in 1912. The theory explains that all the earth’s continents were once connected together before they separated and randomly moved to their current position on the earth’s surface over geologic time.

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.
