If they can successfully produce fertile offspring, they belong to the same species.
Answer:
Correct option is C.
Explanation:
Gram staining is a technique of separation of the bacteria based on the cell wall composition. Steps involved in gram staining are:
1) Primary stain application which is known as crystal voilet, it stains all cells purple/blue.
2) Mordant stain application which is known as iodine solution, is added, and form crystal iodine complex, all cells continue to stain blue/purple.
3) Decoloration step, in this step, we can differentiate gram negative or gram positive bacteria. So, decolorizing agent such as ethanol or acetone extracts blue color from thin walled peptidoglycan layer gram negative bacteria, and gram positive bacteria remain blue/purple because it contains thick walled peptidoglycan layer.
4) Counterstain application in this step safranin red dye stain the gram negative decolorized cells red/pink, and gram positive bacteria remain same blue.
So, if a student is performing a Gram stain of a mixed culture of both E. coli and S. aureus, and he forgets to decolorize with ethanol Both the bacteria should appear blue/purple color.
Let's refer to the statements as A through F.
A. The diagram shows the ocean absorbing "90" and releasing "88". That means the ocean absorbs more than it releases (90 > 88), so acts as a "sink", a place where carbon is stored. (TRUE)
B. The dashed red arrow on the right labeled Fossil Fuel Combustion shows a transfer of carbon into the Atmosphere. (TRUE)
C. The diagram shows "Primary Production and Respiration" as coming from "Vegetation and Soils", so animals are not the sole contributors of CO₂ from respiration. (FALSE)
D. The blue arrows show exchange of atomospheric CO₂ with oceans and land. (TRUE)
E. While "Changing Land Use" contributes a net decrease of atmospheric CO₂, that is more than balanced by "Combustion and Industrial Processes." The net "Anthropogenic flux" appears to be positive into the Atmosphere. (FALSE)
F. The blue arrow into Vegetation and Soils is 120, the blue arrow out is 119, so soils take in more CO₂ by natural processes than they release. Likewise, "Changing Land Use" contributes a net increase in CO₂ in the soils and vegetation. Hence, soils do take in more than they release. (TRUE)
