The graph shows the results of a famous biological experiment. in the experiment, kettlewell believed that the peppered moth demonstrated how environmental pressures influence evolution. he studied two areas. birmingham was a rural wood, with natural conditions. dorset was an urban, industrial area. the moths use tree trunks to camouflage themselves against birds, which are their major predators. natural gene variations produce a light form of the peppered moth, and a dark form, meaning that they are not equally visible.

all but one statement is supported by kettlewell's data. that is

question 1 options:

light moths had a survival advantage in forested birmingham.

dark moths had a survival disadvantage in forested birmingham.

dark moths had a survival disadvantage in industrial dorset.

light moths had a survival disadvantage in industrial dorset.

C. Dark Moths had a survival disadvantage in industrial Dorset

Explanation:

Looking at the graph, you can see that the Dark Moth, compared to the Light Moth actually had a survival advantage.

I won't be explaining the why's to this phenomena, considering that the question is based solely on the graph.

Compare the two bars of Dorset. The Light Colored moths are represented by the green graph while the Dark colored moths are represented by the orange bar. The orange bar extends further that the green bar, showing that they recovered better than the other. So this means they were at an advantage and NOT at a disadvantage.

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.

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.
