Answer:

The correct answer is "respiration".

Explanation:

Cellular respiration is the set of metabolic processes at which the cell obtains energy from nutrients and generates waste products. The cell needs an oxidizing agent in order to obtain energy from nutrients, the most widely used is oxygen. Cellular respiration is a vital process for most organisms, therefore, the depletion of oxygen in the self-contained ecological system most likely occurred from small microorganisms that performed this biological process.

Answer:

a. conservative replication

b. semi conservative replication

c. dispersive replication

d. discontinuous replication

e. continuous replication

The CORRECT ANSWER IS C.

c. dispersive replication

Explanation:

The attached image shows a single band that becomes lighter (in volume) and increase in darker intensity (in times of color) is revealed with consecutive replications. The major pattern that would produce these outcome is dispersive replication.

Conservative replication do reveal two bands (a 14N for the wholly latest molecule, and a 15N for the totally antiquated molecule) after the initial replication. Therefore, this wholly wrong.

Semi-conservative replication reveal an individual band of transitional weight after the initial  replication, followed by two bands following the second replication (one of transitional weight, and the other at the 14N position). These two bands is observed in each following replication, with the transitional weight becoming lighter in color as the 14N band is seen to appear darker in color.

The real pattern gives an individual band that pinpoints to all molecules in an individual replicative cycle possessing the same constituents.

Dispersive replication, has its molecules to be a blend of old (15N) and new (14N) strands. Each replication raises the ratio of new to old strands as it explains the reason an individual band is shown raised (lighter in weight) with every replication.

Serggg [28]

Answer:

1 and 4

Explanation:

Streams and small rivers flow together to create river systems. As the weather gets warmer, the snow and ice from the winter melts, which makes the water flow down the stream and into the larger river system. ... This can result in flooding due to more water draining in than being lost to evaporation.
