4 BIOLOGY FOCUS AREAS for 2014 SCIENCE GATEWAY
Adaptations and Ecosystems
What adaptations increase an organisms ability to survive in its environment. For ex.
structural(anatomical), physiological (biochemical: poisons etc.), behavioral (bird migration) or things like
plant tropisms ( phototropism, gravitropism).
Food Webs and Food Chains
How does an organism get its energy/food (autotroph/producer or heterotroph/consumer or decomposer)
Niche (organisms "role" in its environment), habitat, range
Ecological Changes
This could be human intervention( deforestation, types of pollution etc.)
Or it may be more natural changes that occur in an ecosystem ( primary or secondary succession, pioneer
communities, climax communities)
What impact does the loss of one species have on others? example missing link in a food chain.
Genetics (given in fall)
Mendelian Genetics ( punnett squares, genotypes, phenotypes, dominant and recessive alleles,
heterozygous, homozyous)
Molecular Genetics (DNA, double helix, nucleotides, Protein synthesis/translation, transcription, mRNA,
tRNA, rRNA, ribosomes, nucleus, mutations etc); mitosis and meiosis.
Energy Transformation
Law of Conservation of Energy and matter (especially as it applies to food chains, energy pyramids)
The 10% rule (how much energy moves from one level of the pyramid/chain into the next level.
More energy available in producers (plants, algae, cyanobacteria)
Matter is cycled in an ecosystem but energy flows through (like in a food chain).
Please Note:
In addition to these possible 4 topics for the Spring 2014 Gateway is Solutions. Chemistry
students completed this unit and have review guides.
