BIOL 121 – The Unity of Life Instructor: DW Buckalew Office: 305A Sciences Office Hours: M 3:00 – 5:00 pm F 8:00-10:00 am
Welcome aboard! The Biosphere is the limit!!
How to Succeed in Science courses Attendance is a MUST – you will need to take notes! Timeliness is a MUST – you need to be present to take notes! Read the textbook from this day forward…. Begin projects early Don’t be rude – turn off cell phones, refrain from talking Biology I is essentially Intro Biochemistry – look at the topics! You’ve seen/heard much of the info before? Probably so. You’ve had to synthesize the amount req’d for Biology I? Probably not.
How to Succeed in Science courses COMMUNICATE – talk with faculty when problems arise (notice the word “IF” was not used) “ROLL WITH THE PUNCHES” – bounce back from low test/quiz scores DELAY IMMEDIATE GRATIFICATION – the pursuit of the degree is difficult KEEP YOUR EYES ON THE PRIZE – graduation is closer than you think! Work Hard!!

Your name here (‘11) – attending graduate school at…. - attending professional school at… - teaching science at…… -lab/field scientist at/for…. Your future begins today!!
Hot Topics in Biology: Emerging/Re-emerging diseases
Hot Topics in Biology: Global Warming
Hot Topics in Biology: Decline in Biodiversity
Hot Topics in Biology: Fetal Stem Cells
Career options – what’s out there Professional scientists –often immersed in research and development academia government industry –Often requires a Ph.D. or other advanced degree degree Science-trained professionals –Often employed by industry, business, education, and government in different ways –Usually requires a M.S. or equivalent degree
You can enter many science careers with a B.S. Research technician Lab coordinator Regulatory agent Quality control specialist Life science product sales Biology B.S. with additional study: Science journalism Medical technology 1° and 2° education Pharmaceutical/agrichemical sales Bioinformatics including law enforcement Museum curator Biology B.S. combined with other degree (i.e., MBA, JD) High tech business or hospital management Financial analyst of biotechnology firms Patent law/technology transfer/environmental law Environmental engineering
Biology Ph.D. : Average of 5-7 years beyond B.S. College/university teacher Research director in academia, government, and industry M.D.: Average of 4 years beyond PLUS 4+ years of residency/specialized training Other professional medical degrees… P.A. D.V.M PharmD. D.D.S. D.P.T. D.P.M. D.O.M. The number of Biology Ph.D.’s employed in business and industry has increased steadily…over 50% of new Ph.D.’s are employed outside academia (Tobias, 2005) Over 1/3 have moved into management roles Typically obtained via paid assistantships
So let’s get started in the quest…. Chapter 1- The Science of Biology Biology is “the study of life” I. Characteristics of life: –Cellular organization –Order –Sensitivity –Growth, development, and reproduction –Energy utilization –Evolutionary adaptation –Homeostasis
II. The Hierarchical organization of life At the cellular level… Atoms join to form molecules Molecules join to form larger molecules (e.g. organics) Large molecules are assembled to form organelles Organelles are contained within a larger organized cell
II. The Hierarchical organization of life At the organismal level… Cells organized in 3 levels: tissue organ organ system The set of organ systems form the intact organism
II. The Hierarchical organization of life At the population level… Individual organisms form populations All populations of a single type of organism constitute the species All populations of different organisms living together in one place make a community The biological community PLUS the abiotic factors make up an ecosystem
III. The Process of Science (science = L. “to know”) Charles Darwin ( ) sought natural rather than supernatural causes for the unity/diversity of nature and, in doing so, revolutionized biology. Published the then controversial book, On the Origin of Species…etc in 1859.
The Process of Science Science seeks answers to natural phenomena –Activities that can be observed and measured –Activities that can be verified through testing
The Process of Science Science uses 2 ways to approach problem solving… –Inductive reasoning = Generalization that summarizes many observations –Deductive reasoning = Hypothesis testing and “if-then logic” – reasoning flows from general to specific
How Science Is Done Science is a systematic process of testing alternative hypotheses
Unifying Themes of Science Cell theory –Robert Hooke (1665) to Anton van Leeuwenhoek (1700) to Schleiden and Schwann (1839) –All living organisms are made of cells, and all living cells come from other living cells. –Later, it was proposed that all cell came from pre-existing cells. Molecular theory – “central dogma of molecular biology” –DNA is the molecule of inheritance –DNA encodes genes which make-up and control living organisms. –DNA RNA Protein
Unifying Themes of Science Evolutionary change –Life-forms have evolved varying characteristics to adapt to varied environments. Evolutionary conservation –Some characteristics of earlier organisms are preserved and passed on to future generations.
