Answer:
In eukaryotic cells you find core and proximal promoters.
Promotors are specific DNA sequences where transcription factors (proteins) and RNA polymerase binds to initiate transcription. Promotors are located upstream the coding sequence
Core promoters are where RNA polymersae binds and proximal promoters are where transcription factors bind.
Enhancer elements are DNA sequences where transcription factors (proteins) bind to increase the rate of expresion of an specific gene. Enhancers can be located either upstream, downstream or thousands of nucleotids away from the of the coding region.
Explanation:
Promoters and enhancer are key elements for controling gene regulation. Transcription begins when chromatin rearranges from a condensed state to a accesible state, this allow to transcrition factors and RNA polymerase to bind specif DNA sequences (promotors). Proteins bind to enhancers , this complex develops a DNA loop, so that the protein that is bound to the enhancer interacts with the RNA polymersase. When this interaction is made, the activity of the RNA polymerase is increased.
Answer:
The bedbugs began to die, but then they mutated to become immune to the chemical being used on them, so then they were able to regain their population. Most of the time, in order to get rid of bedbugs, people just burn their mattress' because bedbugs mutate and become immune fast becase their life cycle is so short.

Answer:
coatis would increase
sloths would increase
fruit bats would increase
Explanation:
The boa constrictor in this food chain is the top predator, thus it is on the top of the food chain. It preys on several of the animals on this list, such as the coati, sloth, and fruit bats, so it is regulating their numbers. If the boa constrictor is removed from the ecosystem, the ecosystem will lose its predator, so the animals on which the boa constrictor preyed upon will have no threat, thus will experience rapid increase in their numbers. The coatis, sloths, and fruit bats, all will be predator free in this scenario, so they will all experience increase in their population, which in turn will have big effect on all other species in the ecosystem.
