The microbes present in the experiment were:
S. cerevisiae
S. epidermis
A way of categorizing microbes is according to the environment that they need to live in. In other words, we can classify them as isotonic, halotolerant and halophile.
If we put these two microbes in solutions of increasing concentrations, 1%, 7% and 15%, we will see that:
- S. cerevisiae only grows when it is in a 1% solution.
- S. epidermis only grows when it is in a 1% and 7% solution.
In conclusion, S.cerevisiae prefers an isotonic environment. S. epidermis is halotolerant since it can grow in a more hypertonic environment. As none of them grows in a highly hypertonic solution, neither of them are halophile.

Answer:
C. Electron beams have much shorter wavelengths than visible light
Explanation:
A beam of electrons is used to illuminate and create magnified images of specimens in an electron microscope. The resolution of a microscope increases with a decrease in the wavelength of the light it uses for illumination. The wavelength of electrons used in the electron microscope is about 100,000 times shorter than that of visible light. Therefore electron microscopes have a resolution thousand times better than the light microscope.
