A scientist performs an experiment in which they create an artificial cell with a selectively permeable membrane through which o
nly water can pass. They inject a 5M solution of glucose into the cell and then place the cell into a beaker of water. After an hour, what effect do you expect to observe? A. Water moves into the cell
B. Water moves out of the cell
C. Glucose moves out of the cell
D. Glucose moves into the cell
E. No net change in cell weight
Explanation:water moves into the cell through osmosis.during osmosis water moves from a region of low concentration of solute to a region of high concentration of solute.the glucose introduced into the cell makes it more concentrated.
In this case the cell is hypertonic and water would enter into the cell through the semi permeable membrane.this membrane allows water to pass through but not glucose.this movement of water into the cell causes the cell to become turgid.
The correct answer is less than 8% of DNA is active. But here's only 3options are available so the answer is 1%. Other DNA is in an inactive form. Only 8% of DNA is performing functions of the body actively.
