Answer:
Explanation:
The most common method for testing individuals for COVID-19 involves the use of a polymerase chain reaction (PCR) test, which detects the genetic material of the SARS-CoV-2 virus. To perform this test, a healthcare professional takes a swab of mucus from the individual's nose or throat and sends it to a laboratory for analysis. The laboratory uses a special chemical process to amplify any viral genetic material that may be present in the sample, allowing it to be detected and identified. If the virus is present in the sample, the individual is considered to be COVID-19 positive; if it's not present, the individual is considered negative. Other types of COVID-19 tests, such as antigen tests and antibody tests, are also available but may have lower accuracy or sensitivity compared to PCR tests.
Define the term Eustress​
Answer:
Eustress is a term used to describe a positive or beneficial form of stress. Eustress is experienced in situations where an individual perceives the stressor as a challenge that can be met, rather than as a threat that is overwhelming. Eustress is associated with positive emotions, motivation, and increased performance or productivity. Examples of situations that can create eustress include receiving a promotion, getting married, or participating in a competitive sports event. While eustress can still cause physical and emotional arousal, it is generally perceived as a manageable or even enjoyable experience, and can have a positive impact on an individual's overall well-being.
