Answer:

Promoter:

Promoter may be defined as the region of DNA that are responsible for the transcription initiation of a gene. Promoters are located on the upstream region of DNA. RNA polymerase binds to the site of promoter.

Activator:

Activators are the factors that are responsible for the activation of transcription initiation. These factors helps in the binding of polymerase with the promoter region.

Repressor:

Repressors are the factors that decreases the rate of transcription. The presence of a repressor inhibits the binding of the RNA polymerase with the promoter.

In what way does the endocrine system cause homeostasis
kap26 [50]

Answer:

Explanation:

The endocrine system plays an important role in homeostasis because hormones regulate the activity of body cells. The release of hormones into the blood is controlled by a stimulus. For example, the stimulus either causes an increase or a decrease in the amount of hormone secreted. Then, the response to a stimulus changes the internal conditions and may itself become a new stimulus. This self-adjusting mechanism is called feedback regulation.
