Marissa is conducting an experiment in which she needs to test for acids in water. She is using a substance she believes will tu
rn green when put into different acid solutions. She finds that sometimes the substance turns green but other times it does not. Marissa wants to use this substance in her experiments, but it must consistently turn green in the presence of acid. Which approach should she take to solve her problem?
Answer: she wants the water to turn green and green is neutral on the PH scale. If the water is turning acidic she might want to add a bit of baking soda to balance out the acidity with a bit of alkaline. Minerals can balance acid. If the water is too much of a base she may consider adding something a little acidic to balance it.
Microbiologists are essential in helping us to treat diseases. Many work as biomedical scientists in hospitals and laboratories: testing samples of body tissue, blood and fluids to diagnose infections, monitor treatments or track disease outbreaks.
<span>Bacterial genome is prone to mutational changes due to its simple nature and less efficient DNA repair mechanisms compared to humans, thus it has more chances of obtaining new genetic traits.</span>
It is the smallest unit of life that can replicate independently. It's the basic structural, functional, and biological unit of all known living organisms. The study of this is called cell biology.
