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 (<u>see figure</u>). 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).

What are some outcomes of nuclear fusion?

Svetlanka [38]

Answer:

A. produce larger materials from the collision of smaller materials

Explanation:

The outcome of nuclear fusion reaction is that it produces larger materials from the collision of smaller materials.

Nuclear fusion is the combination of small atomic nuclei into larger ones with the release of a large amount of energy.
The energy released provides the needed temperature for another set of atoms to fuse.
This process in turn yields a bulkier material accompanied with the release of a lot of energy.
