Three part Question
1. There is a standing debate among biologists involved in looking for life on other planets as to how any alien organism should be handled. Some feel that alien organisms should not be introduced on Earth; others feel that investigating these alien organisms will provide important information. What are some of the arguments on both sides?
2. Many studies of potentially useful new drugs involve the use of two groups of people. One group takes the drugs and another group takes a placebo (like a sugar pill). Members of both groups do not know whether they are taking the drug or the placebo. What is the reason for designing these experiments this way?
3. Consider the following statement: Plants violate one of the major characteristics of life because they are immobile. Do you agree or disagree with this statement? Defend your answer.
