Answer:
c. smear preparation
a. fixation
b. application of staining dyes
Explanation:
In the bacterial specimen preparation and staining order, the first step would be Smear preparation in which the smear of bacteria is formed on the slide.
Then the bacterial smear is heat-fixed so that the smear does not get washed off during the washing process in the staining procedure. After heat fixing the bacterial smear, the dyes are applied to the bacterial smear to stain the bacterial cells.  
Therefore the correct order is-
c. smear preparation
a. fixation
b. application of staining dyes

Answer:
 The concentration gradient is the driving force. 
Explanation:
Passive transport of substance occurs when they are moved from the region of their higher concentration to that of their lower concentration. The concentration gradient is the difference in the concentration of substances between two regions or across the membrane. The concentration gradient of substances drives their passive movement. The passive movement of substances does not use metabolic energy.  Simple diffusion and facilitated diffusion are two examples of this transport.
