i did some tests in the lab but its really difficult identifying them based on the results gotten i've consulted text books but everything seems the same

Why not just take a swab of the teats and put them in a petri dish, I'm sure the cow really misses them, or maybe they are teats from some other mammal?\n\nSorry, I just couldn't resist!

Look at their conjugate bases and whichever is more stable will have the weakest acid. PKA values are also easy to prove this becuase it is a realtion of the H+ content.

This sounds like a lab question and we don't have the details. Possible differences are lab versus standard conditions, quality of equipment, and impure reagents.

Is this a lab exercise?

Probably a t-test. \n\nTell us what hypothesis you are testing.

We did a blood test on ourselves back in 9th grade biology class! Guess they don't teach that in school anymore. LOL

What you describe looks as if it is a gum from the tree(usually)which has settled on the rock and has the natural salts of the rock diffused into it . If you are still in trouble then go to the nearest research Lab to get the exact details of the elements present in this specimen.

i dont know but try doing a search in webmd for it

Sorry, no one can diagnose you based on a description.  Go see a doctor and then, not only can you be diagnosed, you can be treated...properly.

say u are going to perform a test for anion A in some sample. but you know that this test may also have a positive result with other anions B and C. \n\nyou then have to take into consideration that B and C might give you false positives as u test for A. if the background of the sample suggests it may contain B and C then find a way to remove these without affecting A.\n\nthen test for A using your originally proposed method.\n\n\nnow for the example:\nyou are to test for chloride ions. the reagent that comes to mind is aq silver nitrate which will result in white ppt of AgCl. then you realise that a ppt will form with any halide ion such as Br- and I-. you also know that AgBr and AgI solids will dissolve in ammonia while AgCl will not. so you first add ammonia to the sample, then test with silver nitrate. voila, now if a ppt forms, you will know it is AgCl only, and of course the conclusion that Cl- was present.

ud need to go see a Dr who would send u to a blood taking place. and the dr would tell them what to look for in your blood

it depends on the test results

Here is what i found.  I'm not sure how right this is, but you can check it out.  Good Luck with your testing.

well you need to see a doctor for further evaluation, there are a few things one can do on examination that can not be described, good luck

Your blood type depends on the blood type of your parents. So if their bloodtype is known you can make a good guess of your bloodtype. \nBut to be ascertain you'll have to get pricked .. Btw .. it doesnt hurt or something .. they just take a droplet of your blood for this test ..

There are certain identifiable characteristics that can be found in some blood samples. The most prominent example is Sickle Cell anemia.  \nThat's just from blood. However, from DNA markers, it is possible to identify certain genomes that would give you a pre-disposition to certain races.  It may not be a definative race, but it could narrow down possibilities until you can come up with a high probability.

Well, it could be MS, but I think she should also be tested for Antiphospholipid Antibody Syndrome and APS can mimic MS symptoms.\n\nI will give you some links so you can compare the two.  Email me if you have more questions.
