Awesome example of adaptation

Thanks to Ms. Heitzman we have can read a blog and see fantastic photos of an amazing fish with bifocal eye lenses. This fish has one eye with two lenses; one to see above water and one to see below water... at the SAME TIME.

Be warned, the blog it is on is called "Ugly Overload."

Have a great summer.

Final Class Review

Biology Finals:
Friday 6-6-09 for B day
Monday 6-9-09 for A day

Most of the 60 question multiple choice exam will focus on macromolecules, cells, DNA, and evolution. There will be also be some questions about the scientific method, variables and reading charts and graphs. Anything we’ve covered in class may be on the final.

Review chapters 3, 4, 5, 6, 9, and 13 in our AGS biology book. If you took notes on the chapters, as assigned, you will have a much easier time.

Review your notes on the readings and notes from class. QUIZ YOURSELF or work with a partner to quiz each other to see if you know what the terms mean in your own words.

I may make the final open notes so bring your complete notes just incase.

Topics you must make sure you can demonstrate your knowledge about:

Experiments: for example, independent and dependent variables

Macromoleules: for example, lipids, proteins, carbohydrates, nucleic acids

Atomic structure: for example, electrons, protons, neutrons

Homeostasis: for example, osmosis, hypertonic and hypotonic solutions

Cells: for example, organelles such as nucleus, mitochondria, membranes and chloroplasts, as well as photosynthesis and ATP,

DNA: for example, cytosine, guanine, thiamine, adenine, deoxyribose backbone, codons, mutations, replication, base pairing, double helix

Genes: for example, genetic engineering, genotype, transgenic species, mutations

Human Genome: for example, percent of shared DNA with other species

Mitosis: for example, interphase, prophase, metaphase, anaphase, telophase, cytokinesis cell division, cancer

Meiosis: for example, production of gametes

Evolution: for example, natural selection, common descent, common ancestors, Origin of Species, Charles Darwin, Lamarck, evidence, homologous structures, biogeography

HOMEWORK: Write at least 15 test questions with an answers including at least one Q and A for each of the above topics. This is due the day of the final as a review.
