I'm gonna start reviewing bio and putting up random notes for my references :) while listening to my HSJ/7 music, which I finally figured out how to upload on my iPod. Hopefully I can get through at least a chapter a day and be done in a month, but knowing me, I'm probably going to do the first like 5-10 chapters today and not do it for a while >.<;.
[my comments will be in brackets...]
I. Introduction [this is like 7th grade review >.<]
A. Biology - the study of life, which includes examining the processes that govern how life is maintained and reproduced, and observing how living things interact with each other and their environments.
- 1. Two perspectives from which one can study biology: in vivo, or in vitro
--- in vivo - "done on the body itself"
--- in vitro - "in glass" experiments one in test tubes aka outside the body
[...experimenting on the person him/herself rather than stuffing the person into a testtube, then experimenting! I see the difference xD.]
B. Scientific Method!!
- 1. Asking questions!
- 2. Form hypothesis and make predictions!
- 3. Testing the hypothesis through experiments [yay this is when u get to blow up stuff]
- 4. Repeating investigations and devising new ways to further test the hypothesis (may include modifying the hypothesis)
- 5. Reporting results and drawing conclusions. [drawing is fun...]
Definition: theory - similar to hypothesis, but theory usually explains a broad range of related phenomena, not just one
Note: "There is no beginning and end in science." All hypothesis are based on previous experiments, and all results/conclusions and be further expanded! Sometimes, experiments might even raise more questions than they answer!
C. Characteristics of Life [What makes us living? aka how to prove to Mr. Waldeck that a candle is NOT alive.]
- 1. Order and Organization - All living things have nucleic acids as the storage mechanism for genetic information, and are made up of cells. [Yes candles are made up of cells... but ...I don't think they have DNA... poll on this?]
- 2. Growth and Development - all living things grow and develop during their life, aka grow into a more complex organism or increase size. [...I don't think candels grow but if you think about it, you can add wax onto it and it'll "grow"...]
- 3. Reproduction - This is sorta self-explanatory, but they must reproduce so their species can survive [candle reproduction = Mr. Waldeck cuts off a piece of the candle. Candles can reproduce! Which is why we still have them in our houses... in case the new technology called electricity fails, but then again we also have firewood...]
- 4. Energy metabolism - all living organisms need energy to survive. Those that make their own food are called autotrophs. All others are called heterotrophs. Nutrients are converted into energy [respiration!] and waste products have to be ELIMINATED. [Of course candles use energy... the fire~]
-- 5. Stimuli response and homeostasis - the ability to respond to the environment(internal or external environment). Organisms must adapt to their environments [naturally or what humans do: create their own environment: A/C!!] [Yes candles adapt to their environment very well. When it gets windy, it just blows out!]
-- 6. Evolution - The ability to change/mutate in order to create diversity!! [Azns, White ppl, etc.] [Yes as you can see, we have many different types of candles in our world.]
D. Structure and function
-- The correlation between the structure and its function is very important in biology! [that's basically what this part says......]
E. Using this book
-- "Remeber: the MCAT stresses your problem solving skills and your knowledge of basic biological concepts. Therefore, you will be better prepared for the test by understanding these concepts rather by just memorizing various facts and terms [lol. tis what Kyumin continuously yells at me for]..."
