Answer:
Not all members of a species are the same. Every species exhibits_____ . For example, some beetles are green, while others are brown.
VARIATION
Not all individuals in a population will survive to reproduce. Those that do, pass their _____, to their offspring.
TRAITS;GENES
Answer:
2) is chemically specific
Explanation:
Enzymes are organic catalysts which speed up or control chemical reactions in cells. Enzymes are specific in the reactions they catalyze. An enzyme will only catalyze one specific reaction or a group of closely related reaction. Enzyme salivary amylase found in the mouth only hydrolyses starch into maltose.
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>
A major study has shed new light on the dim layer of the ocean called the "twilight zone" -- where mysterious processes affect the ocean's ability to absorb and store carbon dioxide accumulating in our atmosphere.
