A cell whose cytoplasm has a concentration of 0.02 mo lar glucose is placed in a test tube of water containing 0.02 molar glucos
e. Assuming that glucose is not actively transported into the cell, which of the following terms describes the tonicity of the external solution relative to the cytoplasm of the cell? A) hypertonic
B) turgid
C) isotonic
D) flaccid
E) hypotonic
If the solute concentration of the cell and that of its surrounding medium are the same there will be no net flow of water in either directions. In this case, the external solution is said to be isotonic to the cell.
Both the cytoplasm concentration and the glucose in the test tube are the same.
. DNA replication is a highly accurate process, but mistakes can occasionally occur as when a DNA polymerase inserts a wrong base. Uncorrected mistakes may sometimes lead to serious consequences, such as cancer. ... Mutations: In this interactive, you can “edit” a DNA strand and cause a mutation.
