PEA stands for Phenylethyl Alcohol Agar medium. It is a selective solid medium that is used to culture Gram Positive bacteria. In this medium, phenylethyl alcohol is an active ingredient that inhibits the growth of Gram Negative bacteria. It causes leakage in the cell membrane of Gram Negative bacteria. It is also used for the growth of obligate anaerobic bacteria.
There are multiple factors that don't play a part in water movement. We need a list of possible options.

Match each biodiversity restoration method to its description we have:
- reforestation: using plants to absorb harmful compounds
- biological augmentation: using plants to control a native plant population
- bioremediation:using plants to increase biodiversity and food resources
<h3>What are ecological restoration techniques?</h3>
Some examples of induced ecological restoration methodologies are the conduction of natural regeneration, nucleation techniques, enrichment or diversity planting, among others.
In this case, the ecological restoration techniques are:
- reforestation: using plants to absorb harmful compounds
- biological augmentation: using plants to control a native plant population
- bioremediation: using plants to increase biodiversity and food resources

Answer:
The correct answer is - Control microcosms did not contain living moss, while experimental microcosms did contain living moss.
Explanation:
The difference between the control microcosms and experiment Microcosms is, the presence of the living moss in the experimental group whereas the control group does not contain living moss.
The independent variable in this research setting is the presence or absence of the living moss and for the control group, the mosses are filtered out and only added the water.
