The answer would be 25%
Carbon 14 is radioactive material with 5700 year of half-time which will change it into carbon-12, a more stable substance. If the age of the fossil is 11,400 years old, then the amount of half-time passed would be: 11,400 years/ (5,700years/ half-time)= 2 half-time.
Since it undergo 2 half-time, the percentage should be: 100% * (1/2)^2= 25%
The question is incomplete as it does not have the option which are:
-acid-fast
-DAPI
-lipo
-Gram
Answer:
Acid-fast staining
Explanation:
Acid-fast staining is the technique used to stain and identify the species of the mycobacterium.
During the acid-fast staining, the carbolfuchsin stain is used to color the bacteria as carbolfuchsin solubilizes the lipid of the bacterial wall and the pink stain enters the cell. When these cells are treated with the methylene blue counterstain, the mycobacterium due to the presence of thick cell wall does not allow the entry of the methylene blue as a result of which they appear red o pink.
Thus, acid-fast staining is correct.
Royal colonies: Another term for provincial colonies; colonies that were under the direct control of the King, who usually appointed a Royal Governor. proprietary colonies: Owned by a person (always a white male) or family, who could make laws and appoint officials as he or they pleased.
I would say extreme temperatures.
