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:
Deletion in a nearby gene, chromosome breakage, and translocation of the gene to a heterochromatic location.
Explanation:
Transposable components (TEs), also known as "jumping genes," are DNA sequences that moves starting with one area on the genome then onto the next, in some cases making or reversing mutation and changing the cell's hereditary character and genome size.
At the point when the transposon is extracted from the original site, it may remove a portion of the gene sections alongside it. This prompts the presence of a serious phenotype. Transposable components can likewise cause chromosome breakage. On the off chance that the whole gene is moved alongside the transposon to a heterochromatic location, the gene gets silenced
Answer: Temperature on monday morning is 319,5K
Explanation: This is an example of Gay Lussac law on gases which states that at constant volume, pressure and temperature are directly related, so if one raises the other one does as well.
The equation that follow the law is :
P1 / T1 = P2/T2 where 1 is the initial pressure and temperature and 2 is the final state.
In this equation, values have to be expressed in atm for pressure and Kelvin for temperature.
The missing value is T2 (monday temperature), so we have to clear it from the equation
T2 =P2.T1/P1
Replacing values:
T2 = 1,073 atm . 338K /1,135 atm
T2 = 319,5 K
