When writing a research paper, look for credible sources. Science doesn’t show bias, but humans do. Avoid sites and articles that provide facts without citing proper scientific evidence. You must be able to identify reliable sites so that the data in your research paper is credible. Use sources that end in .gov. These government sites are reliable sources. You can also use sites ending in .edu. They’re generally trustworthy, but sometimes students, rather than scientists, write content for .edu websites. Always identify the source’s author. Some .org and .com sites are credible, but it’s important to verify their authenticity. When reviewing a source, ask these questions:

Who is the author?
Is this person an expert on the subject?
What is the document’s purpose?
Does the document state facts that scientists can prove with evidence?
Are there opinions in the document?
How old is the document?
Do other credible sources support the statements in the document?
Search for credible websites and note the information they contain. Write down three sources that you’ll use for your research paper, and cite them using Modern Language Association (MLA) (citation methods) link

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.

explanation:

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
