You are doing an experiment on bacteria on the petri dishes your classroom is about 60 degrees Fahrenheit and its been 2 days already your science project is due in 3 days Will the medium bacteria gro?

How can scientists identify specific bacteria when they are amplifying and studying the same region of DNA in each species?
Scientists already know the DNA sequencing for most bacteria. So, to identify a certain bacteria they will look at the same sections of DNA to determine the sequence. The sequence of nucleotides will then be examined by the scientists to see if they match with the sequences of other bacteria.
Why should you not return unused solutions or solids to the stock bottles?
The solutions or solids have already touched other surfaces or objects causing them to be contaminated and more bacteria/ or other living cell forms to be put into the substance that were not there to begin with.
Why is it difficult to test for nitrogen gas in the lab?
The air on Earth is a mixture of several different gases, however it is primarily Nitrogen (Approx. 78%). Thus, it is difficult to test for the presence of Nitrogen as the result of an experiment because it is already present in abundant supply in the air around you.
Will a magnet pick up more nails when covered in copper wire or metal wire?
copper wire because we all know that metal strengthens the magnetic field but copper has a special property that strengthens the magnetic field further so copper is the answer P.S. i already did the experiment
How much is 98.3 Celsius in Fahrenheit?
You can use the online conversion offered by Google: in a Google search field (you may have one on your computer's browser already, otherwise go to google.com) write the number of degrees and the units ("C" or "F" or "K") then "in" and the units you want to convert to.Then hit Enter (sometimes you do not even have to do that!)
How did Pasteur's experiment show tht bacteria do not arise in broth?
He demonstrated that new bacteria appeared in broth only when they were produced by living bacteria. The experiments of Redi and Pasteur helped to convince people that living things do not arise from nonliving material.
How does the background research helps in the design of an experiment?
Background research helps in the design of an experiment because it provides information that is already known about the experiment.
Round 932 Fahrenheit to nearest whole degree?
It's already there.
Bacteria do not arise spontaneously in broth?
bacteria do not arise spontaneously by boiling the broth & showing that bacteria appear only when living bacteria were already present.
What would a scientist do after forming a testable question?
He would develop an experiment. He has already made his hypothesis, he already drew his conclusion, and has already analyzed his data. To develop an experiment is the last possible thing for him to do. Good luck on whatever you needed this for hun. ;)
Do bacteria eat your insides?
No, bacteria doesn't eat your insides. In fact, you already have bacteria inside your intestines that help you survive life.
Where can I buy a classroom projector ?
You can purchase a classroom projector through E-bay. You shouldn't need one to pursue your education, as most schools will have one already in the class room.
What should occur in a probability experiment?
An event, unless it already had been occured and the experiment tries to resolve posterior probabilities on the event
What is the simplest rule for estimating Fahrenheit when you already know the Celsius scale?
Why estimate? Use this formula. Temperature Fahrenheit = Temperature Celsius(1.80) + 32
What eats plant life that has already died?
worms and bacteria
What did hershey and chase find through their experiment with virus-infected bacteria?
The idea of their experiment was to determine what kind of macromolecule was the genetic material, DNA or proteins. Bacteriophages, viruses that infect bacteria, were known to carry all of the information needed to make themselves, but using the genetic machinery of their hosts. Based on this, they were used as a simple system that should be governed by the same principals as the genetic information of the bacteria itself. At the time it was known that nearly all phosphorus in macromolecules is found in nucleic acid, and nearly all sulfur is found in proteins (methionine and cycteine). So if you grow cells in radioactive isotopes of phosphorus, the nucleic acids (e.g. DNA) become radioactive, and if you grow cells in radioactive sulfur, proteins become radioactive. Sorry, there's more. Folks studying infection of bacteria by phage found that most of the virus was a "package" that never entered the cell. So if they mixed phage with bacteria and waited 15 minutes and then put the mix in a blender for a few seconds, the packages that had been attached to the outside of the bacteria get ripped off and can be searated from the bacteria. While the packages are no longer attached to the bacteria, the bacteria are already infected, so the virus genes must already be inside. Now the experiment: Hershey and Chase infected bacteria with phage with racdioactive proteins (sulfur) or in a separate experiment radioactive DNA (phosphorus). The bacteria was mixed with virus for 15 minutes, then whoosh, frappe! They then separated the bacteria from the viruses that had not infected bacteria and empty packages, and asked what kind of radioactive macromoleules were able to get inside the bacteria following the short incubation. In the sulfur experiment , the bacteria were NOT radioactive so proteins appeared to not enter the bacteria during this short time frame. In the phosphorus experiment, the bacteria became radioactive after a short incubation, meaning the DNA of the phage had entered the bacteria in the same time frame as the genetic material. This was consistent with DNA being the genetic material of bacteriophage.
What Is a predicted outcome of a experiment?
It is what you expect to happen before you actually carry out the experiment, based on the knowledge and theory you already have and know. *called a hypothesis
