All the bacteria would appear purple(gram- positive)
Explanation:
Gram stain is used for distinguishing gram-positive and gram-negative bacteria. Gram-positive bacteria appear purple because it does not gets destain after decolorizing step and gram-negative bacteria appears read or pink because it gets decolorized after decolorizing step and then it gets stained by safranin which provides a pink color to gram-negative bacteria.
So if a student forgot the decolorizing step then gram-negative bacteria will not get decolorized and will not take safranin stain so even gram-negative cells will appear violet. Therefore all the bacteria will appear violet or purple(gram-positive).
i dont understand what you are saying but water gets evaporated from the oceans due to the suns warmth all the water vapors condense, once the clouds get too heavy and there are too many water vapors in the cloud for it to handle, it percipitates (rains)
