The dust bowl was the result of a series of dryers drought in the 1930s Where millions of pounds of topsoil were desiccated and

o-na [289]

Answer:

B) Absence of native grasses

Explanation:

The grasses, which acted as a windbreak and whose roots anchored the soil in place, were overgrazed and/or removed to allow for farming. Once a few years of severe drought affected the area, any wind storm was able to blow the topsoil away, rendering the farm land of the Great Plains virtually unusable in many areas. Ground cover is an essential part of sustainable agriculture.

Theodor W. Engelmann illuminated a filament of algae with light that passed through a prism, thus exposing different segments of

WARRIOR [948]

Answer:

The correct answer is C and Engelmann conducted this experiment to prove relationship between algae and the rate of photosynthesis.

Explanation: First we must talk about 3 facts:

1) Prism scatters the white light into different wavelengths.

2) Photosynthesis, 6 carbon dioxide and 6 water molecules are consumed and 6 oxygen and 1 sugar molecule is synthesized using light energy.

6CO2 + 6H2O → C6H12O6 + 6O2

3) Aerobic bacteria breaks down sugar while using oxygen and produces water and carbon dioxide in simplified terms.

So with this experimental setup a researcher can understand the rate of the photosynthesis by increased accumulation of aerobic bacteria near algae in certain wavelengths since they uses oxygen and tend to move close to the oxygen source (see figure). In this experiment there are no ways to measure heat (B), there is no known relation between wavelength of light and aerobic respiration since it can happen even in the dark (A) and finally there are no ways to measure carbon dioxide (D).
