Answer:
c. make a smear for a differential stain.
Explanation:
After isolating a pure culture it is necessary to inoculate the microorganism in a differential medium. Differential culture media enable the differentiation of microorganisms or groups of microorganisms. These media contain specific dyes or chemicals for growth of desired microorganisms.
The term that best describes the 10% salt solution relative to the cytoplasm of the cell is ' Hypertonic'
Explanation:
When the concentration of two solutionare compared they can be described as hypertonic, hypotonic or isotonic with relation to one another.
When two solutions have same concentration and osmotic pressure they are said to be isotonic solutions.
The solution which has higher molecular concentration and higher osmotic pressure than the other solution is called hypertonic solution.
The solution which has lower molecular concentration and lower osmotic pressure with respect to other solution is called hypotonic solution.
Here the solution of salt has a higher concentration than cell sap so it is a hypertonic.
Because all organisms are made up of cells and there are different types of cells which carry different functions.
Because it is heavier air :)
