Evaluate the impact of care in the community for adults with Mental Health problems. Care in the community is where a patient is no longer detained nor sectioned within a hospital institution. However‚ there must be at least three practitioners agreeing that it is necessary for the patient to be released into the community. Adults who may suffer from mental health problems can ask to be cared for within the community. Patients and their families are now more educated with a sense of empowerment

Marine biology is more than the scientific study of marine life. Marine biology is the study of marine organisms‚ their behaviors‚ and interactions with the environment. Marine biologists study oceanography and the associated fields of chemical‚ physical‚ and geological oceanography. Marine biologists are also able to specialize in large aquatic animals‚ all the way down to microscopic and minuscule organisms. Anything else in between‚ marine biologists are able to study. Marine biology is known

Discuss the chain of events that led to the discovery of DNA as the heritable substance and the discovery of the structure of DNA. Ans> The chain of events led to the discovery of DNA as the heritable substance and the discovery of the structure of DNA. In the late nineteenth century‚ a German biochemist Friedrich Miescher found the nucleic acids which are long-chain polymers of nucleotides‚ and are made up of sugar‚ phosphoric acid‚ and several nitrogen-containing bases. Later it was found
