This may seem like a silly suggestion, but try representing the elements mentioned in your textbook (which I'm sure has some illustrations) with pieces of paper, matches, beans or something like that, so you can understand the events and the outcome. \nNow, if you _really_ want an explanation, here it comes (I've ommited the names of the phases, they'll be in your textbook).\n\nMeiosis includes 2 cell divisions with different characteristics. \nWe start with a diploid (2 n) cell, in which DNA duplication has occurred so that each DNA strand is double. These strands do not yet appear as chromosomes (condensed bodies); in fact, the chromatin strands have to be "relaxed" in order to duplicate. \n\n***Meiosis I: (in which the nº of chromosomes decreases to half)\n1. The chromatin (DNA strands) starts to condense and appears as small dense dots (the chromosomes) within the cell nucleus. These chromosomes will each have 2 "arms" (they look like an X or a V) because the DNA in each has been duplicated.\n2. Now all these chromosomes align in homologous pairs, with the aid of a transparent structure formed by tiny intracellular fibers (the spindle) that has formed and will help them to move in orderly fashion within the nucleus.\n3. While they keep condensing, each homologous chromosome contacts its "brother", and they exchange some fragments of their DNA ("crossing over"). Usually only one "arm" of each  chromosome participates in crossing over. \n4. In the meantime, the nuclear membrane is disintegrating...\n5. The pairs of homologues, still united, align at the middle (equator) of the spindle... \n6... and then each pair of homologues is divided, one chromosome of each pair goes toward each "pole" of the spindle. \n7. New nuclear membranes form around the 2 groups of chromosomes. Each of these groups will only have ONE of each pair of homologues. Essentially the information in each new nucleus is the same, BUT has some differences because, as you recall, there has been crossing over i.e. partial exchange of DNA between homologues. \n8. The original cell with the 2 nuclei divides and forms 2 cells, with half the nº of chromosomes of the original cell (haploid or n). Each of the chromosomes still has a duplicate DNA strand.\n\n... the cell takes a short break (you can take a break too!)... but the chromatin does not duplicate this time (it's already done that)\n\n***Meiosis II: (in which each double DNA strand becomes single again, this phase is similar to a normal mitosis).\n1. The chromatin condenses again, so that it appears as chromosomes.\n2. This time the spindle aligns the center of each chromosome at its equator.\n3. The central part of the chromosome is duplicated and the sister "arms" (chromatids) separate, each migrating to opposite poles.\n4. Now you have two groups of chromosomes, each group still has the haploid (n) nº of chromosomes (the same amount with which they started this 2nd meiosis) but now, each chromosome has a single DNA strand. \nA new nuclear membrane forms around each of these groups of chromosomes.\n5. The rest of the cell divides.\n\nSo, to sum up: you started with ONE diploid cell. You end with FOUR haploid cells. In animals, this process only happens during the production of gametes. \nIf we're talking about the formation of female gametes, then only ONE of the 4 resulting cells will become an ovule (and that only after more maturation), the other 3 cells form "polar bodies".\nIn contrast, when it's spermatozoids being produced, all FOUR resulting cells will become spermatozoids. \nThat's one of the reasons sperm is cheaper than ovules! There's just more of them in the entire animal kingdom.\n\nNow, what is the purpose of this extremely complicated (the above is a very simplified version) process? The result will be cells that have half the chromosomes of the normal body cells. These cells

The big O.\nWhy?  Read your biology book- it will do you good to put a little effort into answering this question yourself.  That way you might remember the answer when your 6th grade teacher puts this question on your test.

the website below should give you all the info you need...it even has pictures and everything.\n\n\nhttp://users.rcn.com/jkimball.ma.ultranet/BiologyPages/G/GasExchange.html

Thank you for being honest instead of just expecting someone to do your homework for you... you may have to read and comprehend this - but it might help you get done what you need to get done \n\nhttp://www.vtaide.com/png/foodchains.htm\n\ngood luck !!

I apologize but all that i can come up with is one.\n\nYou could raise fruit flies (Drosphila) and relate them to Gentics. i.e. punnet sqaures, Gregory Mendel, common characteristics, principle of dominance and recessiveness, etc.\n\nif you would like me to go further into detail about this project, please e-mail me at \n\nthe_lonley_kender@yahoo.com or send me an IM on Yahoo! at the_lonley_kender or on AIM at  thelonleykender

I dont know if this will help but here is a web site I found!\n\nhttp://www.biochemj.org/bj/119/0017/1190017.pdf

emm...is this your homework??well..it seems that the question is not from you (individually). Hmm..for more understanding, check out this website:\n\nhttp://faculty.clintoncc.suny.edu/faculty/Michael.Gregory/files/Bio%20101/Bio%20101%20Lectures/Biochemistry/biochemi.htm\n\nI hope it solves your dillema, good luck :)

If you want me to use those specific terms it sounds like you're going to just copy what I write for your assignment.  I'd be happy to explain the process to you, by I'm not going to write your homework paper.\n\nThe idea is that plants produce food using energy from the sun, and all other life either directly eats plants or eats things that eat plants.  So all life (except some protists, that, like plants, can make their own food) lives on energy that the plants have harvested from the sun.\n\nI hope you already know what the laws of thermodynamics, photosynthesis, and respiration are.  If not, pay more attention in class or look them up on Wikipedia.  You should be able to figure out how to phrase the explaination in a way that uses those terms on your own.

I agree with birchardv here...........we need the rest of the problem, and you would learn a lot more if you did the homework yourself.  But do whatever floats your boat.  Add the rest of the problem and I'll get back to you.\n\nOkay Chemist, this problem is really long; if you want a good answer with plenty of steps, I'll need more room.  Email me and I'll send you the solution.

well i am into engineering,,,,so don know much abt biology.\nU can check this website for some good info.\nwww.wikipedia.org
