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.

Explanation:
I would say shape, hardness, and texture
Answer:
I think it is the last one
Answer:
D. The presence of aquaporins (proteins that form water channels in the membrane) should speed up the process of osmosis.
Explanation:
Water moves in the cells through osmosis which means water moves from its higher concentration to lower concentration. In many animals and plants, water channels are also present which is called aquaporins which allow the water to move through it in and out of cell more quickly.
The rate of diffusion by channel proteins is higher than simple diffusion therefore the aquaporins speed up the process of osmosis. No ATP is required to transport the water through aquaporin channel proteins.
