The salt concentration in a cell's cytoplasm is 0.9%. The cell is placed in a 10% salt solution. Which term best describes the 1
fenix001 [56]

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.

In his attempt to develop a pneumonia vaccine, Frederick Griffith injected mice with various combinations of living and dead bac
n200080 [17]

Answer:

The mice died

Explanation:

In Griffith's experiment, two strains of the same bacteria were used. S strain was smooth because it had a polysaccharide coat. This coat also made it virulent because mouse immune system was not able to destroy it and ultimately the mice died. R strain was rough because it did not have the coat and thus was harmless to mice.

When Griffith injected mice with dead S bacteria and living R bacteria together, the mice died. Live R bacteria had taken up the genetic material or as Griffith called "transforming principle" from the dead S bacteria and transformed into S bacteria. So live S bacteria were present again and they killed the mice.
