There are two different species of finch that live on the same small island, species a and
species b. both species successfully feed and reproduce on the island. species a nests in
pine trees and eats large seeds. species b nests in hollowed-out dead logs and eats small
insects.
the factor most often acting as a selecting agent for the survival of a species in a particular location is the
(1) strength of the organism (3) speed of the organism
(2) new mutations within the individual (4) environment they inhabit

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.

i wish i could with all of them i can barley see the first one so here's the answer to the first one b
