The conclusion needs to <u>be backed up by more </u><u>evidences</u> only then scientists make a claim.
Finding one type of bacteria that can survive in an oxygen-free environment does not prove that many other organisms can as well. It is important to understand the biological processes that give <u>organisms the traits that enable them to live in settings devoid of </u><u>oxygen</u>. More data from many groups of species are required to support the statement.
<h3>In what all conditions can bacteria thrive?</h3>
Although bacteria can survive at higher and lower temperatures than humans, they thrive in an environment that is <u>warm, wet, protein-rich, and</u><u> pH neutral</u><u> or </u><u>slightly acidic</u><u>.</u> However, there are several exceptions. While certain bacteria can <u>survive in extremely hot or cold </u><u>environments</u>, others can endure excessively acidic or salty environments. The danger zone, or the temperature range <u>between 41 and 135 degrees Fahrenheit</u>, is where most pathogenic bacteria thrive.
