Why scientists should use controls in their experiments?
Because If they don't, the scientists won't know what the difference is in.Example:You have two glasses of water. One is labeled control.The other is labeled salt. The one labeled controlhas nothing added to it. The one labeled salt has salt added to it. Is there a difference between the two glasses?If an experiment has a control in it, that means the scientist needs to know if there is a difference in the experiment.
Which property of the wave is labeled A?
The amplitude of a wave is generally labeled 'A'.
Does Germ-X kill 99 percent of germs?
Its possible it kills all of the germs, probably it did in many trials however in some cases it cannot in which it must be labeled 99 percent.
A Metronome marking of 200 would most likely be labeled?

At an international science convention a sample of gas was labeled 20.26?
0.2
What kind of molecule must be labeled to make radioactively labeled DNA?
Radioactive nucleotide
What enzyme us used to make radioactively labeled DNA?
DNA polymerase
Can be used to compare the amount of radioactively labeled DNA in two or more samples?
Scintillation counter
Can be use to determine the precise amount of radioactively labeled DNA in a chemical solution?
scintillation counter. APEX
Can DNA polymerase be used to determine the general location of radioactively labeled DNA?
Geiger Counter
You briefly expose bacteria undergoing DNA replication to radioactively labeled nucleotides when you centrifuge the DNA isolated from the bacteria the DNA separates into two classes one class of la?
The DNA separated into two classes: labeled DNA and unlabeled DNA. The labeled DNA contains the radioactively labeled nucleotides that were incorporated during DNA replication, while the unlabeled DNA represents the original, non-radioactively labeled DNA from the bacteria. The centrifugation process separated the DNA based on density, with the heavier labeled DNA migrating to a higher position in the centrifuge tube compared to the unlabeled DNA.
Cells of the pancreas will incorporate radioactively labeled amino acids into proteins?
ER golgi vesicles that fuse with plasma membrane
What are radioactively tagged bacteriophages to discover that DNA not protein is injected into host cells?
Radioactively tagged bacteriophages are used to confirm that DNA, not protein, is injected into host cells during infection. The radioactively labeled DNA can be detected inside the host cells after infection, providing evidence that DNA is the genetic material transferred by the bacteriophages. This experiment was crucial in establishing DNA as the genetic material in organisms.
What of the following reactions is used to radioactively label DNA?
The reaction that is commonly used to radioactively label DNA is the nick translation method, where a DNA molecule is treated with a DNA polymerase, dNTPs (including radioactive ones), and a DNAase to create radioactive labeled DNA fragments.
Why did scientists developed the prime meridian in 1884?
scientist wanted a starting point that was labeled 0 degrees.
What is laboratory technique in which the body radioactively labeled a substance is mixed with a blood specimen?
The laboratory technique you are referring to is known as radioimmunoassay (RIA). In RIA, a radioactive substance is used to label a specific molecule or antigen, and when this labeled molecule is mixed with a blood specimen containing the corresponding antibody, the level of radioactivity can be used to quantify the amount of antigen present in the blood sample.
How do the radioactively labeled dideoxynucleotides terminate DNA synthesis?
Dideoxynucleotides have no OH group on the sugar of the nucleotides, only H's. That means phosphate groups can't react with the sugar to form a phosphodiester bond to join two nucleotides together, so DNA syntheses is terminated
