The researchers set up experimental and control microcosms, or small artificial ecosystems, to measure the release of minerals f

rom rocks. First, they placed rock fragments of volcanic origin, either granite or andesite, into small glass containers. Then they made a suspension of water and macerated (chopped and crushed) moss of the species Physcomitrella patens. They added this mixture of water and moss to the experimental microcosms. For the control microcosms, they filtered out the moss and just added the water. After 130 days, they measured the amounts of various minerals found in the water in the control microcosms and in the water and moss in the experimental microcosms. How did the setup of the control and experimental microcosms differ

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.

What causes ocean water to become denser?
Solnce55 [7]
There are two things that cause ocean water to become denser, and those are b) the salinity of water and low temperatures.
The more salt there is, the denser the water will be - take the lake Dead Sea in Israel, Jordan, and Palestine for example.
And the lower the temperature, again, the denser the water will be - the deeper you go into an ocean, it will be more difficult to move around due to density and other things.
