What do Astronauts need to take on the moon so that plants could grow in a lunar plant growth chamber

1. Biogeography, the study of the geographic distribution of plants, animals, and other forms of life. It is concerned not only with habitation patterns but also with the factors responsible for variations in distribution.

2. weathering and other natural forces break down the substrate, rock, enough for the establishment of certain hearty plants and lichens with few soil requirements, known as pioneer species. These species help to further break down the mineral-rich lava into soil where other, less hardy species can grow and eventually replace the pioneer species. In addition, as these early species grow and die, they add to an ever-growing layer of decomposing organic material and contribute to soil formation. This process repeats multiple times during succession. At each stage, new species move into an area, often due to changes to the environment made by the preceding species, and may replace their predecessors. At some point, the community may reach a relatively stable state and stop changing in composition. However, it's unclear if there is always—or even usually—a stable endpoint to succession.

3. I don’t have the video so I’m going to take. Wild guess. Just look up types of finches

4. Broadly speaking, different species are unable to interbreed and produce healthy, fertile offspring due to barriers called mechanisms of reproductive isolation.
These barriers can be split into two categories based on when they act: prezygotic and postzygotic.

I tried my best hope this helps :)

CONTRACTILE RINGS are a contractile ring of actin micro filaments that eventually results in the division of the cytoplasm.
The contractile ring are usually formed during the early anaphase phase of the cell division cycle. During the cellular cleavage, the contractile rings tighten around the cytoplasm of the cell until it is pinched into two daughter cells.

juan earn $11 per hour and works at most 30 hours per week. identify the independent and dependent quantity in the situation, an

Vlad [161]

Answer:

The hours are the independent variable.
The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked ) .
The domain is 0 to 30
The range is 0 to 330

Explanation:

The hours are the independent variable and should be plotted on the x-axis .

The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked ) and should be plotted on the y-axis

---------------

Let +W+ = wages/wk earned

Let +h+ = hours/wk worked

The equation is:

+W+=+11h+

The domain is 0 to 30

( no hrs worked to 30 hrs worked )

The range is 0 to 330

( no wages eared to +11%2A30+=+330+ earned )
