A class of lipids called prostaglandins is typically produced at the sites of injury or infection and is used to treat both disease and injury. They regulate functions like blood flow, blood clot formation, inflammation, as well as labor induction.
Arachidonic acid, from whom prostaglandins are generated, is what causes inflammation:
- In synthetic form, prostaglandins are used to induce labor and give birth.
- They trigger uterine contractions and have a ring structure with at least two or three and perhaps more carbons.
Effects of prostaglandins in the body are
- The hormone that circulates and regulates the kidney's reabsorption of sodium. Prostaglandins, which seem to be present in high concentrations, directly affect nerve terminals to induce pain.
- The production of the inflammatory response is significantly influenced by prostaglandins. Their production is markedly increased in inflamed tissue, therefore they help to produce the essential symptoms of acute inflammation.
- NSAIDs (which inhibit cyclooxygenase) as well as COX-2 selective inhibitors, sometimes known as coxibs, were examples of prostaglandin antagonists. Cyclopentenone prostaglandins as well as corticosteroids, which block the formation of phospholipase A2, might help to reduce inflammation.

Answer:
The answer is (C) studying how is has been affected by erosion
Explanation:
Answer:
The ocean produces oxygen through the plants (phytoplankton, kelp, and algal plankton) that live in it. These plants produce oxygen as a byproduct of photosynthesis, a process which converts carbon dioxide and sunlight into sugars the organism can use for energy.

Answer:
d. regulatory; operator; regulatory
Explanation:
In prokaryotes, the regulation of gene expression is done at the transcription level by operons. Examples are the lac operon and the trp operon. To initiate transcription, RNA polymerase and a DNA segment are required for binding called a promoter.
DNA segments that are close to the promoter serve as binding sites for regulatory, activating or repressing proteins. They are called operons.
The Operon is a regulatory sequence close to prokaryotic DNA that lies between the structural genes and the promoter. It is responsible for controlling the transcription of structural genes. When the repressor, encoded by the regulatory gene, binds to the operator, the promoter is blocked which prevents transcription.
The Promoter is located next to an operator and is the site in the DNA molecule that binds to RNA polymerase (which is a regulatory protein) to initiate transcription.
