pls help need answers and scientific facts from scientists! have a project due in lyk 4 days! ahhhhh help me im going to die~! love ur luver shawna i love you if u give me an answer! (and no i dont need mental help! just help wit my project im gonna die if i dont get answers!)

Given the fact that women usually have higher metabolic rates than men therefore, women usually have a slightly higher pulse rate than men.\n\nKeep in mind that there are many other factors that have a much more significant impact on pulse rate than gender.

OMFG. I love ScienceFair, and I hate it all in the same.\n\nUse my topic: Magnets.\nHypothesis: Does temperature affect the strenth of magnets?\nProcedure(truncated):\nTake however many magnets you need for your trials(mine was 45) and separate them into even groups of 3. Example, 3 groupd of 15 from 45. Test a regular set, one magnet at a time, with 50 paper clips, and see how many it picks up out of 50.\n\nNext, take your second set, and put them in the freezer for 24 hours. When they're done, test that set and record how many paperclips they pick up out of 50.\n\nFinally, take your 3rd set and boil them. Test them, holding the magnet with tongs, and record your data. \n\nNOTE**** Important: You can't use only one set of magnets, the boiling and freezing off sets the balance inside the magnet!!!

Hmm, you are in luck.  I am a biologist/chemist with a little ecology and botany knowledge and I might be able to help you out here.  But in the future, procrastination is not the answer.  Trust me, I know.\n\nAnywho, on with your project.  And, kudos to your teach.  He is getting you ready for college.  Lets see, you are wanting to germinate seeds.  It would be feasable to choose seeds with very quick germination times as probably you don't have a very long time to perform this experiment.  Some grasses will germinate in as little as 7 days.  With a little research, you can find your own seeds to use.  Next, you are going to have to decide what treatments you want to apply to each group.  And by each group, you need to have more than one "cup" of seeds, more like 4 or 5.  That is for replication.  By treatments, you could use things like adding different types of fertalizer in each group.  Use fertalizers that differ in the amount of phosphourus, nitrogen, and potassium (3 primary nutrients required by plants.)  Then, with multiple groups recieving the same kinds of fertalizer, vary the amount of sunlight (preferably artificial, like an incandesant lamp) and amount of water given.  What you will end up with is something like this:\n\nfertalizer A - 15 cups; each cup gets 1 tb of fertalizer\n      Cups 1-5 get 10mL of water and 12 hrs of "sunlight" daily\n      Cups 6-10 get 10mL of water and no "sunlight" daily\n      Cups 11-15 get no water and 12 hrs of "sunlight" daily\nRepeat this for say, 3 or 4 different types of fertalizer over a 10 to 15 day period.  Also, have 15 cups that follow the above procedure but get NO fertalizer.  After the 10 to 15 days, compare growth of the plants by measuring (probably in mm) the amount of growth produced.  \n\nBy performing a little research of your own and whatever plant seed you decide to use, you can base your hypothesis on how each fertalizer "should" affect your seeds and how much they "should" grow.\n\nFor example, lets say nitrogen is the main nutrient needed by grass.  Any of the fertalizers used that are low in nitrogen would not grow as much as the ones that get the nitrogen.  And those that do get the nitrogen, the ones that get water and sun will grow more than the others that get only sun or only water.  So, your hypothesis would be something like this:  The seeds that recieve adequate amounts of light, water, and nitrogen will have more growth after x amount of days than the other plants.  Then, you perform the experiment and see what you get.  \n\nGood luck on your experiment and if you remember, let me know what your teach thinks and what grade you get!

Apparently so, but this is all I could find.  Next time start working on your project sooner :)\n\nhttp://www.all-science-fair-projects.com/science_fair_projects/40/511/876cb29d53dd2afebdeaadc98cecc049.html

right on, I'm glad someone else sees some of the problems with evolutions.  Everyone else, keep in mind that this protein is just one of millions that is vital to life as we know it.  And another thing how do we know that the world is 4 billion years old?  Carbon dating?  The half life of carbon 14 is 5,730 years.  So how many half lives is that. Simply put by 4 billion years there no carbon 14 left to measure, it would have all deteriorated.  There is no way that all the life on earth could have resulted by evolution\n\nOkay to everyone above, to the person who said that scientists have created living cells from nonliving molecules, slap yourself because that is an absolute falsehood.  Next when you say that scientist created amino acids that is true but lets look closer.  There were only about 5 different amino acids that were created not all the ones that are necessary for life.  Next how were all the other cell parts (lipids, nucleic acids, carbs) formed.  Did they just appear? Scientists cannot make lipids from just the molecules needed to synthesize them.  I have a very hard time believing that all these parts were formed, in the same place (it is very hard to keep things together underwater let alone in an ocean) and somehow all came together and then replicated.  No that does not happen.  \n\nNext how did new material get added in to the gene pool? Mutation?  Well everything that we know from science (Medicine, genetics) tells us that mutation is bad.  Name one good mutation.  Not sickle cell anemia.  First of all sickle cell is only beneficial when it is in the heterozygote and so it helps protect against malaria, it also cause way more harmful symptoms than beneficial ones.  Look at what happens with people that have cystic fibrosis.  There are a few (less than 10) nucleic acid changes and it is usually fatal.  Mutation does not, repeat, DOES NOT, provide helpful change.  Another thing is how did this first cell survive?  Even the simplest cell carry out complex reactions, and processes that "Scientists" cannot explain after years of study.  In order for this "first cell" to be viable all these pathways would have to present before the cell could live.  And what about all the proteins need for DNA/RNA replication?  There are about 150 different proteins that carry out karyokinesis alone and then comes the problem of separating the DNA.  Come on do you still think that all this could have happened by chance?  \n\nNext time, do not come after creationist because you do not want to believe that there is a God.  With creation everything fits.  The more you know about biology the more you see the holes in evolution.

You know, MythBusters did an experiment on this once.\n\nhttp://kwc.org/mythbusters/2003/09/mythbusters.html\n\nRead the second bullet point.

Sounds like an interesting project you are undertaking - very interesting!!  Hope these sites help you out!

It isn't a very good control if your cells die before the experiment is complete.  More info is needed to get a more specific answer.

Hello Maggie,\n\nDon't worry: the egg drop project is a classic for science teachers, and, therefore, there are a lot of solutions out there on the web. Check out the following site, you'll find all the answers you need, and more: http://users.adelphia.net/~jberger5/eggdrop.html

I'm also doing an environmental project (school). I found lots of interesting stuff by asking the people around here. Try that but don't say it's your homework or something.
