Who sang the "techno" version of Cotton Eyed Joe in the 90's?
This is driving me crazy!!! I think they also did a song called "Buttermilk Biscuits". Anyone old enough to remember???
2 AnswersMusic1 decade agoIs there anyway to determine what type of bacteria is growing in a petri dish only using the naked eye?
My son is doing a science project and we don't have access to a microscope. We put samples from a few different animals' mouths on agar in a petri dish and we have lots of bacteria growing. I think it would be great if we could identify the bacteria, but I don't know if that is possible without a microscops. Is there a website that can tell us what kind of bacteria we are growing in our petri dishes just by looking at the colonies and their characteristics? Even if we could just find out the general family the bacteria is in, I think that would be helpful. Thanks in advance!
4 AnswersBiology1 decade agoWhat is the best way to collect samples to culture on petri dish with agar?
My son is doing a science project to determine which "animal" has the dirtiest mouth. We have sterile cotton swabs to collect the samples. Do we need to put them in a sterile saline solution first, or will the saliva be wet enough to get a good sample? Also, is it best to rub the swab on the agar or roll it on--does it really matter which method is used? Thanks in advance!
