Mr Rayon

Soz, I can't name 3 differences between RNA and DNA if it is related to school work. Try these sites though:

gl, hope they help.

While on another site reading an article on photographic memory. A simple question came to me. It was "can one improve one's memory without using some sort of trick to it?". For example, without using some sort of mnemonic. So, if one were to constantly memorise things...let's say definitions from a dictionary, will one's ability to remember in that specific way improve as a result of repetition? Or is our ability to memorise things based purely on genetics? Or is it a bit of both?

BTW, I have heard that many people do not believe in the so-called photographic memory. Any theories, or ideas behind it?

Soz, if the first question seems naive, anyway I'd love to hear any thoughts on these. Thanks.

(m) 15- I am totally against abortions even under extreme circumstances. Abortions are wrong and should not be performed. It is unethical. If a problem arises during pregnancy, there is always treatment, it is no excuse to become a murderer.

After a person dies, the muscles stop working (after rigor mortis). I have heard that when the body is put into a constant state where it cannot be moved (for example in a grave), gravity pushes the blood downwards and results in it being located elsewhere in the body. Is this true? If so, how long will it take for the blood to go down? Which route does the blood take to get down?

Thanks

I am doing a biology project on the endoplasmic reticulum; it is on power point and I need some awesome pictures of the organelle. And, when I mean awesome I mean 21st century stuff or if that's too difficult just any clear pictures will do.

Does anyone know where I can get some awesome pictures of them?

All help is appreciated!!!

I understand your situation very well; I want to one day become a doctor as well. I've started studying the basics to it, memorising some medical terms and the kind of stuff you read off textbooks. From doing this I have a slightly more than average knowledge of the subject biology or anything that revolves the human body towards my peers. However, my other subjects remain average and do not stand out as much. As long as you have motivation, ambitions, goals you will probably get to the place you want to be. Make this a time where you put your act together and aim for something you want. Don't waste any more time. You're still young (like me), and at this stage you can choose to be anything you want as long as you are prepared to spend hours studying. And this is coming from a brutally honest person. You will also need a peaceful learning environment to succeed, not an abusive household; this may be your greatest barrier! Good luck.

From your post, I'm guessing you're a night owl. Have you thought of taking advantage of the situation? Night time is a lot more quiet than Day time. Do someting constructive. Read a human body atlas, a science text book, play chess on the net, do a puzzle, or just do some math problems. You'll be surprised by how much you'll learn. I should know that's what I often do when I can't get to sleep. However if you see it more as a problem then why not try slowly sleeping just a little bit later each day until you reach the time where you're supposed to be asleep. Good luck with that by the way.
