Final reflection

Please fill out the following form reflecting on the entire year.  Thank you for being a part of an amazing AP Biology year! :)

Final Review




AP Bio Spring 2014 Study guide


Objectives for AP Bio Spring 2014 Final Resources
This is by no means an exhaustive list.  Remember that places like Khan Academy and Education Portal are great resources. 
You can also search adaptive curriculum for lessons that I haven’t assigned. Use these to help in your studying for the final.  :)

Question

Content/Learning Target

I can…
Resources
1)        
refine scientific models and questions about the effect of complex biotic and abiotic interactions on all biological systems, from cells and organisms to populations, communities and ecosystems

2)        
analyze data to identify possible patterns and relationships between a biotic or abiotic factor and a biological system (cells, organisms, populations, communities or ecosystems)
3)        
predict how a change in genotype, when expressed as a phenotype, provides a variation that can be subject to natural selection.
4)        
describe representations and models that illustrate how genetic information is copied for transmission between generations
5)        
use visual representations to analyze situations or solve problems qualitatively to illustrate how interactions among living systems and with their environment result in the movement of matter and energy.
6)        
explain how biological systems use free energy based on empirical data that all organisms require constant energy input to maintain organization, to grow and to reproduce.
7)        
construct explanations of the influence of environmental factors on the phenotype of an organism.
8)        
create representations and models to describe immune responses
9)        
construct an explanation of the multiple processes that increase variation within a population.
10)    
connect how organisms use negative feedback to maintain their internal environments.
11)    
explain the connection between the sequence and the subcomponents of a biological polymer and its properties (specifically DNA structure)
12)    
describe the connection between the regulation of gene expression and observed differences between individuals in a population.
13)    
explain the connection between genetic variations in organisms and phenotypic variations in populations.
14)    
describe representations and models illustrating how genetic information is translated into polypeptides
15)    
predict how a change in a specific DNA or RNA sequence can result in changes in gene expression.
16)    
construct a representation that connects the process of meiosis to the passage of traits from parent to offspring (i.e. pedigree & Punnett Squares)
17)    
predict the effects of a change in the community’s populations on the community.

AP Bubbling

We are going to do all of the pre-bubbling today for the AP test.  If you are absent, please make sure you see me on the block day to bubble your sheet. :)

Energy Dynamics

What factors govern energy capture, allocation, storage, and transfer between producers and consumers in a terrestrial ecosystem?

BACKGROUND
Almost all life on this planet is powered, either directly or indirectly, by sunlight. Energy captured from sunlight drives the production of energy-rich organic compounds during the process of photosynthesis. These organic compounds create biomass. The net amount of energy captured and stored by the producers in a system is the system’s net productivity. Gross productivity is a measure of the total energy captured. In terrestrial systems, plants play the role of producers. Plants allocate that biomass (energy) to power
their life processes or to store energy. Different plants have different strategies of energy allocation that reflect their role in various ecosystems. For example, annual weedy plants allocate a larger percentage of their biomass production to reproductive processes and seeds than do slower growing perennials. As plants, the producers are consumed or decomposed, and their stored chemical energy powers additional individuals, the
consumers, or trophic levels of the biotic community. Biotic systems run on energy much as economic systems run on money. Energy is generally in limited supply in most communities. Energy dynamics in a biotic community is fundamental to understanding ecological interactions.
To model ecosystem energy dynamics, you will estimate the net primary productivity (NPP) of seeds growing under lights and the flow of energy from plants to butterfly larvae (the consumers) as the larvae eat plants.
The following exercises describe skills and methods for estimating energy flow in a terrestrial ecosystem. Note and record any questions that occur to you as you work through this activity.
 

Questions might include the following:
• What kinds of things affect plant productivity, the growth of cabbage white butterfly larvae, or the interactions of these organisms?
• How do you keep track of energy as it moves through the biological system? Can the techniques used for tracking energy be improved?
• What is the role of energy in ecosystems?


One or more of these questions will help guide you through the final part of this laboratory, where you are expected to carry out your own research project based on one of your questions.
