Which regulatory sequences are bound by activator proteins and associated coactivator proteins to form a protein "bridge" that bends the dna and links the complete initiation complex at the promoter to the activator-coactivator complex, ultimately causing an increase in transcription?

The answer is the Enhancer

Explanation:

Because Enhancer sequences bind specific proteins that interact with the proteins bound at gene promoters, and together promoters and enhancers drive transcription of certain genes.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.

if you listed your answers right then i believe your answer is b.
