Introduction to AP Biology
Transcript of Introduction to AP Biology
Advanced Placement Biology?
4 Big Ideas
BIG IDEA #1
The process of evolution drives the diversity and unity of life.
BIG IDEA #2
Biological Systems utilize free energy and molecular building blocks to grow, to reproduce and to maintain dynamic homeostasis.
BIG IDEA #3
Living systems store, retrieve, transmit and respond to information essential to life processes.
BIG IDEA #4
Biological systems interact, and these systems and their interactions possess complex properties.
-- Theodosius Dobzhansky
Geneticist, Columbia University
"Nothing in biology makes sense except in the light of evolution."
7 Science Practices
From AP Biology: A Summary of Course Revisions
13 "Official" Labs
PREPARING FOR THE EXAM
i.e. COMMON CLASS ACTIVITIES
Doing lab work
Writing....and writing more
Practice Test Taking
Reading, a lot!
What is "AP"?
coursework while still in high school
earn college credit
(exempt you from taking a required class in college & bumps you up to taking a more advanced/specialized class)
demonstrates to college admissions officers that you want to
--valuable, even if you don't do well in the course
Audit process ensures AP class aligns with college standards
by taking the
of 4-yr colleges & universities in the US award
college level credit or advanced placement
(or both) for successful exam scores.
shows that students who score a 3 or higher on AP exams typically experience
greater academic success in college
and have higher rates of graduation than otherwise comparable non-AP peers.
5 = highly qualified
equivalent to scoring an A+ or A in college level class.
4 = well qualified
equivalent to scoring an A-, B+ or B in a college level class
3 = qualified
equivalent to scoring a B-, C+ or C in a college level class.
Less focus on recall of factual detail
More focus on enduring conceptual understandings and the content that supports them.
Inquiry based learning will help you develop essential reasoning skills.
Equivalent to a 2-semester
introductory biology course.
Must do 2 inquiry based labs per Big Idea
Will spend >25% of class time doing labs and working on the 7 science practices/building reasoning skills.
Multiple Choice (90 minutes) & Free response (90 minutes)
Each section is weighted equally (50% of score for M/C; 50% for FRQ)
May use 4 fn calculator with square root ONLY
list will be supplied
sex hormones influence phenotype
glowfish are transgenic animals
a jellyfish gene gives the zebrafish a new phenotype
the central dogma of molecular biology
albinism--what happens when the "code" changes
fight or flight response is alive and well
Geological and meteorlogical events affect living organisms
kudzu, an invasive plant, alters ecosystems
many insects and plants have co-evolved so as to depend on one another--many plants rely on insect pollination to sexually reproduce
water molecules and these phospholipid molecules have different properties and so interact in discrete ways
DNA molecule-a molecule of code--the code for building proteins, the workhorse molecules in cells
Evolution explain diversity & unity
Evolution allows us to explore "degrees of relatedness" and patterns of ancestry
Cellular structure can be explained
by historical, evolutionary events
Many lines of evidence, including a universal genetic code for all of life's diversity support the theory of evolution by natural selection
The tools of molecular biology allow us to "see" evolution at the molecular level--patterns of relatedness among organisms can be explored at the level of proteins & DNA
The great diversity among life's many organism can be explained via the theory of evolution by natural selection.
Mathematical models give us another tool to test our ideas about the process of natural selection.
A building block (glucose) for making an energy storage molecule (starch).
"THE" energy molecule that virtually all of life uses as its energy "currency": ATP
Energy transfer can be seen at the level of communities and ecosystems as this graph shows how energy transfer from hares to lynx affect the population sizes of each.
Energy transfer within the muscle cells of this leopard allow her to reach record speeds for mammals.
