BIL 150 Lecture Notes - Lecture 1: Chemistry, Deductive Reasoning, Auxin
Document Summary
Bil 150 important concepts (the information you actually need from lecture/website) World population growth is a major concern today. Approximate 13 years to gain another 1 billion people. Large n size= faster growth (j curves) Maximum population that a given environment can support. Earth population may begin stabilizing around 2050, 9. 3 billion. Need to consider immigration, emigration, birth and death. Two population curves for u. s. due to immigration. Each couple has 2. 1-2. 5 kids to exactly replace themselves. In u. s. native population decreasing but immigration increasing. Biology is a natural science like physics and chemistry. Modern biology: recognize cell as basic unit of life. Aim= interpret the properties of living organisms within the structure of their molecules. Ex: na, cl make safe/simple table salt. The scientific method is what scientists do for a living. Business analogy: investor does research, makes a prediction, then buys stocks. Hypothesis not falsified but still a return on investment.
