BIL 150 Important Concepts (The information you ACTUALLY need from lecture/website)
Lectures 1 and 2
Lecture 1
World population growth is a major concern today
Approximate 13 years to gain another 1 billion people
Exponential growth
Large N size= faster growth (j curves)
Consider the carrying capacity
Maximum population that a given environment can support
Forms sigmoid growth curve (S shape)
Earth population may begin stabilizing around 2050, 9.3 billion
Global annual percent increase is decreasing
Need to consider immigration, emigration, birth and death
Two population curves for U.S. due to immigration
Replacement Level Fertility
Each couple has 2.1-2.5 kids to exactly replace themselves
In U.S. native population decreasing but immigration increasing
Population Pyramids (age/sex diagrams)
Show dynamics of a population’s growth
Lecture 2
Biology is a natural science like physics and chemistry
Physics studies atomic particles
Forms predictive formulas

Chemistry applied physics
Biology is the most complicated
Applied chemistry in a cell
Not predictive; rules are infinite
History of the study of biology
Traditional biology: study life/living organisms
Modern biology: recognize cell as basic unit of life
Describe properties of cell
aim= interpret the properties of living organisms within the structure of
their molecules
Understand emergent properties
Not predictive based on individual properties
Ex: Na, Cl make safe/simple table salt
Build upon past discoveries
Mendel’s genetics, Darwin, Watson/Crick
The Scientific Method
Scientific theories have 2 components
1. Describe patterns observed in nature
2. Identify a process responsible for the pattern
Must recognize and state the problem
The scientific method is what scientists do for a living
Common practices
Observations
Accurate description of phenomena
Ask questions, do literature searches
Postulate a question
Design a hypothesis that is falsifiable
Make a testable experimental prediction
Business analogy: investor does research, makes a prediction,
then buys stocks
Experimentation as stock value increases
Hypothesis not falsified but still a return on investment
Designing the experiment
Should FALSIFY hypothesis
