What is the difference between evolution and coevolution? a) Evolution of one species only occurs in response to natural selection based on the changing environment that species lives in at a particular time. b) Coevolution is the only way speciation can occur. c) These concepts are not different; they only differ on time scale. d) Coevolution results when two or more species influence adaptation in each other.

d) Coevolution results when two or more species influence adaptation in each other.

Explanation:

The coevolution is a process of evolution in which two or more species affects each other evolution by the process of natural selection. The evolution of one species is dependent upon other species in coevolution process.  The coevolution is affected by the mutualism, predator prey relationships and host parasite relationships.

In the course of evolution of one species adapt to the natural changes occurring in the environment. The changes occurring is one species remain unaffected of the other species.

explanation:

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.
