Some people on here are really rude. I used Nair today, and now I broke out in hives :[[[[[ I didn't do my homework, and I have a biology project due tommorow. I just looked at my legs, it looks like a took a knife to 'em. And I have gym tomm.
Sorry... that sucks... fake sick tomorrow and do your project then you don't have to worry about gym or go and just wear sweatpants
Nair - that's why they say to do a TEST PATCH before you cover your legs in that crap. And if you leave it on for too long, it'll make your skin blechy Bio, well, ya shoulda done the project. Own up to it Gym, eh, you'll be done with that crap soon enough. I haven't had to go to gym class in about 5 years now
Yeah, I'm not going. I got 1 hour and 14 minutes of sleep. And my legs still have hives. And I have a sore throat. This is in the Random Thoughts because it is pointless. Therefore, if you don't like it, don't read it.
I Have my Biology Coursework to Hand in Today... ... Crap... ... It's Not Finished...Need to Do Evaluation... ... Yeah Everyone Has their Bad Days...
I have to draw this poster on Meiosis I. But I keep messing it up. That's what hookie is for. Have a nice day.
My Coursework is Based Upon Potato Chips...O.O This is All I've Done so Far...O.O Also Need Conclusion...And...Everything Else... Experiment: To Examine the Effect of OSMOSIS on two Varieties of Potato Chip (1) From Baking Potato (2) From Sweet Potato. The aim of my experiment is to investigate the effect of Osmosis on two varieties of potato chip. In aid of this experiment I shall be using Molar Sucrose Solution. I shall be observing how the mass of each of the variety of potato chip changes in different amounts of Molar Sucrose Solutions. Simply, will the effect of the action of osmosis be affected by the concentration of the solution? Method For this experiment, I am going to do follow these basic procedures in order: Using a chip cutter, I will cut each potato chip to an exact length of 4.5cm and Cylindrical. I will then weight each chip individually and take note. Each chip variety will be numbered 1-10 and placed into sub group A-B. A chip will then be immersed into each of the following solutions: -Distilled Water -0.2 Molar Sucrose Solution -0.4 Molar Sucrose Solution -0.6 Molar Sucrose Solution -0.8 Molar Sucrose Solution I will time the start of immersion using a stop clock. After 1 hour, I will remove the chips from the solutions. Gently I will blot the excess liquid from the chips and re-weigh each one. I shall then record the differences in masses and calculate the percentage weight changes of the recorded masses when a potato chip has been in different concentrates. Apparatus Set of Scales (accurate 1/100 of a gram) Potato Cutter 12 small glass Beakers 2 beaker Racks Tweezers Whiteboard Paper Towels ---------------------------------------------------------- Prediction I predict that the mass of each variety of potato chip will decrease as the concentration of the Sucrose solution increases. The reasons why I predict this is that a strong solution (from the stand point of water molecules) will have a high concentration of solute molecules, but a low concentration of water molecules. The Potato chips contain a semi-permeable membrane, which contains pores that allow small molecules to pass through, but not large molecules. In Osmosis, the small molecules are water molecules. For this experiment the large molecules will be the solute molecules in the sucrose solutions. Using this theory, I can predict that as the sucrose solution concentration increases, less water molecules will be present, but more solute molecules within the solution. Therefore, the potato chips should, by osmosis, lose mass, as the water molecules pass through the semi-membrane into the high sucrose solution. The potato chips will be unable to gain more mass as there are not enough water molecules present, so overall the mass of each variety of the potato chips should decrease throughout each phase of the experiment. ---------------------------------------------------------- Laugh Away...And Nice Day to You Also... *Dies*
We did something like that before, although we used Sea Monkies. Haa. And we used saline instead of sucrose. But you're in college right? I'm only in 9th grade, though, so it was a lot less complicated than that. I'm glad I didn't go to school, it's super dark and pouring and thundering. Pretty neat.
