When writing a scientific paper, look for the most credible sources. Science doesnt show bias, but we humans tend to show bias. Beware of sites and articles that provide facts without proper scientific evidence. Avoid using information from such sites. You must be able to identify reliable sites so the data in your paper is credible.Use sources that end in .gov (government sites), such as CDC.gov. They are reliable sources. You can also use sites ending in .edu. They can be deemed trustworthy, but sometimes the information is written by students rather than scientists. Always find out who the author of the article is before proceeding. Some .org and .com sites are credible, but you need to analyze the content to verify their authenticity. As you review a source, try to answer these questions:Who authored the article?Is this person a scientific expert in the species Im researching?What is the purpose of the article?Does the article state facts that scientists can prove with evidence?Are there opinions in the article?How old is the article?Do other credible sources support the statements in this article?(HELP NOW!!!!!)

A multi-dimensional being reaches down to Earth and pulls you out of the universe. You are then thrown back into the universe at a place and time of the being's choosing, and you are permitted to leave only after you have identified your surroundings. This process is repeated several times. Through a scientifically unexplainable miracle, you are able to survive in every one of the places that you find yourself. In each scenario below, identify your surroundings (and potentially your cosmic era) from among the choices given. You find yourself in a place that is unimaginably hot and dense. A rapidly changing gravitational field randomly warps space and time. Gripped by these huge fluctuations, you notice that there is but a single, unified force governing the universe. Required:Where are you?
