In the acid-fast or Ziehl-Neelsen stain, following the referred washing, the slide should be covered in 1%-3% acid alcohol to decolourise until the smear turns into light pink. After that, wash well with clean water to stop the decolourisation.
The distance between two adjacent crests of a transverse wave is called the wavelength.
Wavelength is a property of a wave that can be spotted and used as a way of telling waves apart. The parts of the wave that point up are termed crests while any part that is sloping called a trough.
Wavelength is measured in meters. There is no definite spot from which to start on a wave to measure wavelength. The most popular way of measuring wavelength is from crest to the next crest but can also be measured just as accurately from trough to trough.
Answer:
fails to verify
Explanation:
An experiment that <u>fails to verify</u> a hypothesis will often provide a new direction for the researcher.
Researchers conduct experiments to develop hypotheses. A hypothesis is a testable and falsifiable explanation. A hypothesis can be tested. It is possible to prove the hypothesis as true or false.
An experiment is a way to test the hypothesis.
Small fragments of orbiting bodies that have landed on Earth are known as meteorites. If the fragments are still orbiting earth are known as meteoroids. They are not called meteorites until they enter Earth's atmosphere. Once a meteor enters Earth's atmosphere it will begin to burn up. It may burn up completely or lose most of its size by the time is lands on Earth's surface.
