adell [148]

Answer:

B) cAMP

Explanation:

Phosphodiesterase is an enzyme that breaks a phosphodiester bond, for example in molecules such as cAMP and cGMP. So, phosphodiestarases are  are regulators of signal transduction: regulate the duration of signaling pathway.

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>

What could you do to determine whether the outliers in model 2 are authentic measurements?
Over [174]
<span>To determine if a measurement is authentic, you can check whether the measurement makes sense in the context of whatever is being measured. If a measurement is physically impossible, then it is not authentic. If a measurement is inconsistent or far off from multiple repeated measurements of the same kind, then it is not likely to be authentic, so you could test the authenticity by repeating the measurements.</span>

inn [45]
The answer to the first unknown in the problem is the "Areolar" while in the second unknown in the problem is the "Cartilage". Hence, to complete the given statement in the problem, we have an example of a high vascular tissue is "AREOLAR" tissue and as an example also of a tissue that is not highly vascular is the "CARTILAGE".
