Answer:
Biology is the science that studies life, but what exactly is life? This may sound like a silly question with an obvious response, but it is not always easy to define life. For example, a branch of biology called virology studies viruses, which exhibit some of the characteristics of living entities but lack others. It turns out that although viruses can attack living organisms, cause diseases, and even reproduce, they do not meet the criteria that biologists use to define life. Consequently, virologists are not biologists, strictly speaking. Similarly, some biologists study the early molecular evolution that gave rise to life; since the events that preceded life are not biological events, these scientists are also excluded from biology in the strict sense of the term.

Answer:
<h2> Mutant 4: can grow on minimal medium supplemented with T, P, or A.</h2>
Explanation:
In minimal medium, those bacteria who lacks some enzyme which are necessary for the synthesis of all their required compounds can not grow. They require these metabolites supplemented in minimal medium. In this case , if any of these 3 metabolites T,P,A which are required for the synthesis of H are absent in minimal medium,then there will be no bacteria growth.
