Atopography map is used to study the changes in vegetation associated with different elevations. which individual most likely uses them for this purpose?
a scientist
a businessman
a government official
a construction engineer

Answer: a scientist

Explanation:

The study of vegetation is done by botanists, which are plant scientists. Thus, a topography map will be used by a scientist.

Engineers may also used topographic maps. However, it is highly unlikely that  an engineer will ever use such a map to study changes in vegetation associated with different elevations.

creative diagnostics provides a protocol for total protein extraction based on ripa which is widely used.

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.
