helpme1234 Posted November 22, 2005 Share Posted November 22, 2005 I need someone to answer these questions I need them fast my exam is 2morrow and im gona fail!!! 1. Experimental design: discuss the technical aspects of any lab exercise performed this term. This is not the same as lab procedure. What are technical aspects? Like in any lab what would it be? 2. Describe with the aid of three (3) diagrams how the structure (design) of the cell membrane is determined by the nature of its constituents 3. The nature and location of chloroplasts in photosynthetic organisms is a result of their environment. Discuss. 4. Diagram how cells transport materials across the plasma membrane.

ecoli Posted November 22, 2005 Share Posted November 22, 2005 none of these questions would be hard to answer with a quick google search. As for your exam, good luck, but don't you think you should have learned the material before the night before the exam? Link to comment Share on other sites More sharing options...
helpme1234 Posted November 22, 2005 Author Share Posted November 22, 2005 oh but they refuse to help the twist of this is they give us the questions we find the answer we found the questions tdoay and the bigger twist its not in our text book we are in grade 10 if you would help me please or at least source some sites cause when i googled it trust me i didnt understand it Link to comment Share on other sites More sharing options...
helpme1234 Posted November 22, 2005 Author Share Posted November 22, 2005 btw their essay questions Link to comment Share on other sites More sharing options...
RyanJ Posted November 22, 2005 Share Posted November 22, 2005 when i googled it trust me i didnt understand it Isn't that the whole idea? To learn something you did not know before? It would be pointless asking a question if they knew everyone would be able to answer it with no research or applicaiton of knowkedge. Only 30% of my Biology exam is pure learning the rest is applied knowledge and research. If you don't understand the material keep reading it until you do understand it or look for a better reference. A good research resource is here: http://en.wikipedia.org/wiki/ Cheers, Ryan Jones Link to comment Share on other sites More sharing options...

ecoli Posted November 22, 2005 Share Posted November 22, 2005 Ok... I'll try to help you out 1) Well, seeing as how I have no idea what labs you did in school, I can't really help you with that one. 2) Cell membranes are made up of phospholipid bilayers with proteins embedded. here are a ton of sites http://www.google.com/search?q=cell+membranes&start=0&ie=utf-8&oe=utf-8&client=firefox-a&rls=org.mozilla:en-US:official 3) Why are choloroplasts where they are? To maximize their exposure to light is one reason. http://www.google.com/search?hs=HU0&hl=en&lr=&safe=off&client=firefox-a&rls=org.mozilla%3Aen-US%3Aofficial&q=chloroplasts+mitochondria&btnG=Search Link to comment Share on other sites More sharing options...
helpme1234 Posted November 22, 2005 Author Share Posted November 22, 2005 u forgot question ffour and i know for number one i was jus asking what do they mean by "technical aspects" Link to comment Share on other sites More sharing options...
helpme1234 Posted November 22, 2005 Author Share Posted November 22, 2005 thankz ecoli for the help starting to get some good stuff going Link to comment Share on other sites More sharing options...
ecoli Posted November 22, 2005 Share Posted November 22, 2005 you're right I forgot 4... but the links from question 2 will help you out with that one. I'm guessing by technical aspects, they mean what was happening in the labs... what mechanisms were going on, what properties where you testing, and things like that.

RyanJ Posted November 22, 2005 Share Posted November 22, 2005 u forgot question ffourand i know for number one i was jus asking what do they mean by "technical aspects" This may help for #4: http://images.google.com/images?svnum=10&q=%22membrane+transport%22&btnG=Search Or for more information on transportation (The 4 methods of) that may help with diagrams: http://en.wikipedia.org/wiki/Osmosis http://en.wikipedia.org/wiki/Diffusion http://en.wikipedia.org/wiki/Active_transport http://en.wikipedia.org/wiki/Facilitated_diffusion Cheers & good luck, Ryan Jones Link to comment Share on other sites More sharing options...

RyanJ Posted November 22, 2005 Share Posted November 22, 2005 ryanthe way u did question four can u help me on 2 and 3 too cause those listings actualyl made me understand everything 1) No idea realy, depends on thee xperiment. List factors that directly affect the results - how its made a fair test, what factors are kept the same and changed etc. 2) Try these: http://en.wikipedia.org/wiki/Plasma_membrane http://en.wikipedia.org/wiki/Lipid_bilayer http://en.wikipedia.org/wiki/Phospholipid (Most of the stuff here is probably above what you'll be tested on!) http://www.sirinet.net/~jgjohnso/apbio5.html And some images may help too... http://images.google.com/images?&q=%22plasma%20membrane%20structure%22&btnG=Google+Search&sa=N&tab=wi 3) http://en.wikipedia.org/wiki/Chloroplasts http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/L/LightReactions.html http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/C/Chloroplasts.html And images: http://images.google.com/images?q=%22chloroplasts%22&btnG=Search Once again, good luck If you have any actual questions you may also try positng those, I'm shure someone here can help you with them!
