Answers:

D) According to the graph, obesity and diabetes are intertwined, which could be why obesity and diabetes are linked.

E) Diabetes had the greatest rise in prevalence in 1997 until 2000, with prevalence percentages between about 76% to 78%.

Explanation: Explanation for these answers are below:

D) Looking at the graph, obesity and diabetes had similar prevalences in 1997 and 1998, and started to part ways a little in 1999.  In fact, even without the graph, scientists have known for a long time that people who have obesity also have diabetes.  This graph supports that claim because of how closely linked diabetes and obesity are and how similar the prevalence percentages are.

E) Diabetes had the greatest rise in 1997 to 2000, which had a 78% prevalence by 2000.  Obesity had very similar prevalence percentages from 75.5% to 77% in 1997 to 2000.

Tresset [83]

Answer:

An Enhancer

Explanation:

Enhancers are the regulatory sequences and are generally located 80-160 base pairs upstream of the transcription start site. Enhancers have bidirectional elements that are involved in the initiation of transcription. Enhancers serve as the binding sites for activators to increase the concentration of activators in the vicinity of the promoter and thereby increase the rate of transcription of the gene.

According to the given information, the loss of a regulatory sequence led to a reduced level of transcription of the gene. This means that the regulatory sequence was involved in the upregulation of transcription. The presence of the sequence far away from the promoter makes it an enhancer.
