Agroup of nursing students are reviewing the pain-relieving action of nsaids. the students demonstrate understanding of the information when they identify which actions as being blocked to achieve pain relief?

The blocking of the activity of cyclooxygenase- 2.

Explanation:

The NSAIDs or nonsteroidal anti-inflammatory drug mainly prevents COX-2 or cyclooxygenase-2 enzymes from functioning. The NSAIDs are generally a group of medicines, which relieve fever and pain and minimize inflammation. The COX-2 enzymes are accountable for discharging prostaglandins post-injury or after infection.  

The prostaglandins exhibit many different effects, of which one is to monitor inflammation. By mainly preventing COX-2 enzymes, the NSAIDs relieve pain and inflammation with less harmful gastrointestinal effects.  

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
