Phenolphthalein is a pH indicator that is a reddish color at neutral but becomes bright yellow at acidic pH. Suppose you inocula
te a tube of growth media containing phenolphthalein with a pure culture of an unknown microorganism, and after 24 hours the media starts to turn yellow. What can you conclude
We can conclude that the media is acidic in nature because yellowing of the media and we know that yellowing of the media means acidic nature. If the colour of the media is reddish it means that the media has neutral pH. We know that Phenolphthalein is a pH indicator that tells us about the pH of the medium on which a microorganism grow. This chemical allow us to find out the acidity of the medium for the growth of microbes.
Answer: This is because animals (like humans) have more organelles to store in our bodies than bacteria. This makes sense because without all of our organelles we wouldn't be able to function properly. This is just another one of those form=function things.
The water we drink now was the same water the dinosaurs drank. Discuss how the water cycle makes this statement accurate. Include different parts of the water cycle and what processes help move the water through each part.
