Biology - November 18th 2010, 01:45 AM

No matter what, I just can't hold any information in my head for biology. I try so hard to pass but it's slowly becoming harder and harder. I think if it gets any worse than I'm going to go to my counseler and change it to bio 1-2 for second semester. But I don't want to have to do that. Part of the problem is that I have a really hard time focusing when I'm studying for tests, does anyone know how I can focus better so that I can pass?

Re: Biology - November 18th 2010, 07:17 AM

Biology was my favourite (and best) subject in high-school and what I'm doing in university. I'll make up an example just to explain a way I use. Suppose I'm going to learn the steps of mitosis. I would think what has to happen at the end: 2 daughter cells, splitting of cytoplasm and DNA (and necessary protein) replication. When I first learned it, the way I memorized it was prophase has the fewest letters in it, so it's at the start, and in the first phase, chromatin condense. I know there's a metaphase but to prepare for it, there's the prometaphase where everything gets ready in the nucleus, which means its membrane must be degraded. Then, in the metaphase I know there's a plate where chromosomes line up at. Last, in the telophase, I think "telephone", meaning a separate speaker and talking area, so it's when the cell is splitting (can only happen if cytoplasm has already divided). Before telophase, is anaphase and I remembered this because the chromosomes looked like little "A"'s when lined up and the cell was expanding, meaning the "telephone" or telophase was about to begin. I remember anaphase comes before telophase because when you put a normal house phone on its holder, the holder has somewhat a "V" shape, so that reminds me of "A".

You need to use memory but need strategies, whether it's mnemonics (i.e. knowing all the cranial nerves) I use "Oh Once One Takes The Anatomy Final, Very Good Vacations Are Heavenly". Conveniently, this is also roughly the order in which they appear on the brain and brainstem, which made it easier on lab questions of identifying a certain cranial nerve on a brain. The function of each was often easy to know by the nerve's actual name, such as olfactory is for smell, facial is for the face, trigeminal had three branches (hence "tri"-) and vagus was to the heart, lungs, etc... (I thought of Vegas, where there's tons of stuff, so vagus nerve does tons of important stuff).

These examples may not fit with what you're doing or how you learn the best, so expanding on those can help to give you more relevant information.

But it's just colouring in D=

But seriously? Just keep over and over everthing and make analogies for the important things.

Haha, actually, I had my cellular respiration test today and afterwards we got a worksheet ALL about mitosis. xD
And I'll be sure to try and make some mnemonics to help out.
Thank you so much

Biology is so interesting So PM me if you need help and I'll help you
Enzymes (yay) , human bio (yay) Cells (yay) Photosynthesis (WOO)
I love it , didn't take it for post 16 , wonder why?~
BTW mitosis looks hard , but really it's just about cells dividing and duplicating. You have to learn the stages , but mnomics will help




I'm a superstar because I do pageants!
