Compare and contrast adaptive and assistive technology. Give examples.
Both types of technology help living organisms live better lives. However, adaptive technology changes the living organism while assistive technology does not. Examples of assistive: eyeglasses, hearing aids, etc. Examples of adaptive: cochlear implant, artificial heart, other artificial organs

Contrast theory and law.
A theory is an explanation of why something happened the way it did. Theories are repeatedly tested and can be supported by test results. A law is a theory that has been tested and now explains how things work, but not why.

A group of environmental scientists suspects that acid precipitation is beginning to affect certain lakes in Tennessee. What tools and procedures could they use to test their hypothesis? A. Use research studies and research the harmful effects of acid precipitation in lakes. B. Collect acid precipitation in containers and experiment on water plants native to Tennessee. C. Use a field guide and count the number of water plant species found in a Tennessee lake. D. Use sterile containers and equipment, collect lake water samples, and test the pH of each sample.
