current biologists working to solve? - answerOne of the problems that biologists are trying to solve today is how to cure the illnesses we suffer from, such as viruses (HIV), or diseases where the body is killing itself (cancer, ALS). Other problems that biologists take care of include how to create crops that produce more and are able to live in harsher conditions. How would you describe the difference between something that is alive and something that is nonliving? Be able to explain eac...
