Document Summary
Lemurs are great because they"re a case study for evolution. Biology is a study of order, because things tend to fall into disorder. Science is derived from the latin word for to know . Eventually establish a theory that others build on. Evolution has been made an enemy of religion, when really they address different questions. Evolution connects to real life, including medicine, agriculture, forensics, conservation. Humans are now influencing the environment in powerful ways. We talkin bout elements, chemical bonds, and water. 4 elements make up 96% of human mass, o c h and n. Isotopes are useful, attach to cancer for pet scan, biochemical rates tracking, dating. We"ve also got a bunch of trace elements. Start with a hypothesis, prove or disprove it. Supported by a large, growing body of evidence that weeds out liars. When atoms are unequal in electronegativity, you get polarity. Plants use cohesion to help transport water without a heart.
