The Solutions in the Arms of a U-Tube Are Separated

question 10

Multiple Choice

The solutions in the arms of a U-tube are separated at the bottom of the tube by a selectively permeable membrane. The membrane is permeable to sodium chloride but not to glucose. Side A is filled with a solution of 0.4 M glucose and 0.5 M sodium chloride (NaCl) , and side B is filled with a solution containing 0.8 M glucose and 0.4 M sodium chloride. Initially, the volume in both arms is the same. Refer to the figure to answer the following questions.

-If you examine side A after three days, you should find

• A) a decrease in the concentration of NaCl and glucose and an increase in the water level.
• B) a decrease in the concentration of NaCl, an increase in water level, and no change in the concentration of glucose.
• C) no net change in the system.
• D) a decrease in the concentration of NaCl and a decrease in the water level.
• E) no change in the concentration of NaCl and glucose and an increase in the water level.

Definitions:

Elasticity

The ability of tissue or material to resume its normal shape after being stretched, compressed, or altered in any way.

Chronic Wounds

Wounds that fail to proceed through the normal stages of healing in an orderly and timely manner, often remaining open for an extended period.

Full-Thickness Wounds

Wounds that extend through the dermis to affect deeper tissues and potentially muscle or bone, requiring more complex healing processes.

Healing Time

The duration required for the body to fully recover from an injury, surgery, or illness, which can vary based on the severity and individual health factors.
