Answer:
YELLOW
Explanation:
Phenol red is a biological indicator used to monitor changes in pH. The phenol red indicator changes color ranging from yellow to pink with respect to changes in pH. In an acidic pH i.e. <7, the phenol red changes to a YELLOW color while in an alkaline pH i.e. >7, the phenol red changes to a PINK pH.
The presence of carbon dioxide (CO2) increases the hydrogen ion concentration (H+) of a solution (lowering its pH or making it acidic).
Therefore, in a reaction where CO2 is created as a product, it means the CO2 content of that solution increases. Hence, the phenol red solution will be shifting towards the YELLOW color in response to a decreasee in pH (acidic).

The resolving power of the earliest electron microscopes was at least ten times higher than that of the light microscopes, mainly because the wavelength of electrons is much shorter than the wavelength of light.
The electron microscope uses a beam of accelerated electrons to magnify the object whereas the light microscope uses visible light for this purpose. Unlike the light microscope, the electron microscope uses electromagnets as lenses.
The magnification of the electron microscope is much higher as compared to the light microscope and it produces high-resolution images. However, the Specimen preparation of an electron microscope takes several days while the Specimen preparation of the light microscope takes only a few minutes.
