Which of these choices is a positive consequence of the endangered species act with respect to gray wolves? a. the law has been expensive to enforce. b. the wolf population has recovered after being near extinction. c. the law has angered many ranchers. d. the reintroduced wolves are more aggressive than the original wolves.

The correct answer is-

B. The wolf population has recovered after being near extinction.

Grey wolves became endangered ( came in a danger of getting eliminated completely/ extinct) because people considered them pests as they thought that they were destroying their livestocks. So, people took their lands and killed them.

The population of gray wolf was declined to the extent that it was declared endangered by the mid 1900s in the lower 48 states of the US (United States). Due to Endangered Species Act ( that provided protection to increase their number), the wolf population has recovered after being near extinction.

Thus, option B) is the right answer.

the correct answer is phenotype

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.
