Advantage: helps in finding the exact ph value with a narrower range.
Disadvantage: You don't know the exact ph value on a regular scale.
Explanation:
The pH paper is a pH paper with a color indicator that helps in determining the pH value precisely between the 4.5 to 7.5 pH range. It is accurate in comparison to other pH papers such as 0-14 paper. One no need to guess the color between the different colors from various color mixtures as it has a more precise color reading that helps in finding accurate pH value in a narrow range.
On a regular scale, it is not as accurate and one can not find the exact value as it provides a narrow range value between 4.5 to 7.5.
It was an asteroid that came to earth two billions years ago and scientists says that there might be another one coming.so we might live in space for a couple of months or years. so that why the dinosaur die.
A unicellular protist is a eukaryotic cell because it has a nucleus enclosed by a membrane. Protist cannont be grouped with plants, animals or fungi. However they are still eukaryotic.
