Answer:
Endospores Staining
Endospores are substances that are formed inside of specific bacterial cells which boost their survival rate in times of harsh conditions.
Gram staining alone is not sufficient to observe the endospores, which seems apparently clear when Gram-stained cells are observed.
Endospore staining employs two stains to identify endospores from other cell components.
•The Schaeffer-Fulton method employs heat to promote the primary stain (malachite green) into the endospore. Rinsing with water will well wash away the colour from the cell, as the endospore still appears to be green stained. Counterstaining pink with safranin will show the shape and location of endospores, if they are a part of the cell. The green endospores will be seen inside the pink vegetative cells or it will appear distinct from the pink cells in total. If no endospores are seen, only the pink vegetative cells will be observable.
The attached image shows a stained preparation of Bacillus subtilis revealing the endospores as green and its vegetative cells in pink coloration.
Endospore-staining procedures are essential for observing Bacillus and Clostridium, two genera of endospore-forming bacteria, production of bioterrorism agent from B. anthracis (which causes anthrax.
The correct answer is B.

Answer:
Vector
Explanation:
A vector is an organism that transports a disease from one organism to another.
The "short-term effect" of something is the immediate result of something. For example, a short-term effect of drinking alcohol would be the slurring of speech, because that happens soon after you get drunk.
The "long-term" effect of something is the gradual consequence of something. For example, again using alcohol, if you drank large quantities of alcohol consistently for 10 years, the long-term effect would be liver damage, because alcohol can harm the liver in large quantities.

Answer:
In eukaryotic cells, however, the two processes are separated in both space and time: mRNAs are synthesized in the nucleus, and proteins are later made in the cytoplasm.
