  1. Hi, would anyone be able to give me some help on my biology essay? I have to write 650 words on “ The process of diffusion and its importance in living organisms.” I honestly don’t know where to even start. I’ve described diffusion and then gone on to narrate what happens when an organism has to breathe. I’m doing my A-levels. But I am seriously scraping an E. If it’s possible, would anyone be able to give me a laments version on diffusion? I don’t even know what guidelines I should be following, and what other points I should be branching out on? I’ve looked for information on the internet, on wikipedia and other sites. But everything is just a repeat of itself – or maybe I’m not looking hard enough? Thankyou for your time.. and please, help!
  2. Sorry about the wording. Here it is reworded: If I fell 100ft into a deep pool, I would hit the floor QUICKER if it was filled with: a. Plastic balls (like a kid's playroom) b. Polystyrene balls (in beanbags) Sorry if I caused any confusion. It's just me and my friend had a disagreement, she thought that falling in polystyrene would get you 'down' quicker, whereas I thought the opposite .
  3. Question: If I fell 100 feet into a large, deep pool, which of the following would take LONGER to touch the bottom of the pool. 1. Plastic balls (like a kid's playroom) 2. Polystyrene balls (in beanbags) Thanks!
