A. The following statements are hypotheses:
1. Glucose may cause an increase in bacterial growth.
2. Increased glucose may lead to capsule formation in bacteria.

B. The following statements are observations:
1. The bacterial colony grown without glucose do not have capsules around their cells.
2. Bacteria growth in the glucose environment increase rapidly and then stopped after sometime.

Messenger RNA carries a(n) ___________ of the DNA’s instructions out of the nucleus to the ___________.
Nitella [24]


messenger RNA  (mRNA) carries a transcript (copy) of the DNA's instructions out of the nucleus  to the cytoplasm where it attaches to a ribosome.

transfer RNA (tRNA) begins to read (translate) the information on the attached mRNA and corresponding to this information, fetches the appropriate amino acids from the pool of free amino acids in the cytoplasm, and brings them to the ribosome where they are linked into a chain or polymer forming the primary structure of the desired protein.

Mariana [72]

Answer:

C) Bacteria congregated in these areas because these areas had the most oxygen being released.

Explanation:

Below is the full question:

Theodor W. Engelmann illuminated a filament of algae with light that passed through a prism, thus exposing different segments of algae to different wavelengths of light. He added aerobic bacteria and then noted in which areas the bacteria congregated. He noted that the largest groups were found in the areas illuminated by the red and blue light.

What did Engelmann conclude about the congregation of bacteria in the red and blue areas?

A) Bacteria released excess carbon dioxide in these areas.

B) Bacteria congregated in these areas due to an increase in the temperature of the red and blue light.

C) Bacteria congregated in these areas because these areas had the most oxygen being released.

D) Bacteria are attracted to red and blue light and thus these wavelengths are more reactive than other wavelengths.

E) Bacteria congregated in these areas due to an increase in the temperature caused by an increase in photosynthesis.

The most efficient region of white light for photosynthesis has been found to be the blue and red region of the white light. Hence, these two regions must have had the most oxygen being released because they are the regions with the highest rates of photosynthesis.

<em>Aerobic bacteria thrived better in the regions illuminated by red and blue light because these regions had the highest oxygen production as a result of having the highest rates of photosynthesis.</em>

<em>The correct option is C.</em>
