They block communication between enhancers and nontargeted promoters.
Explanation:
Insulator sequences control transcription in multicellular eukaryotes. They are present near the enhancer region of a gene. When required proteins bind to them, they get activated. They interact with the enhancer region and hamper its function. Enhancer sequences increase the rate of transcription by interacting with the promoter region. Insulators block the communication between enhancers and non target promoters by various methods. For example, they can form a loop domain between enhancer and promoter which avoids them form interacting. In this way, transcription is halted.
"Foreshock" and "aftershock" are relative terms. Foreshocks are earthquakes that precede larger earthquakes in the same location. An earthquake cannot be identified as a foreshock until after a larger earthquake in the same area occurs.
The pulmonary circuit transports blood to the lungs. The blood is oxygenated there and then carried back to the heart. Gaseous exchange happens in the lungs:
Carbon dioxide diffuses from the blood into the air in the alveoli.
