Environmental Science 4.09 Mid Term Survey 1. List three natural resources we have studied this semester.

2. What is the difference between renewable and nonrenewable resources?

3. Why is a perpetual resource considered renewable?

4. Briefly describe 3 ways you and your family could minimize solid waste. (Remember: recycle,

reuse and renew!)

5. What accounts for most of the solid waste in a landfill? (See 4.06 Case Study)

What adaptations can prey use to avoid predation

The human genome project is devoted to mapping the general dna sequence of our species. this could lead to the development of new medicines, as well as the possibility of using gene therapy to treat certain diseases. however, there are some ethical issues surrounding the mapping of individual genomes. one concern is a) that your genes may change over time, making the project useless. b) that insurance companies could discriminate based on genetic make-up. c) that since this has never been done before, we should probably not do it now. d) that sequencing our individual genomes is so expensive, it is a counter-productive strategy.
