Question

Which of the following is found in Bowman's space? (Select all that apply.)

		solutes from the blood
		large proteins
		water
		glucose
		wastes

Water moves from regions of: (Select all that apply.)

		low solute concentration to regions of high solute concentration.
		low water concentration to regions of low solute concentration.
		high solute concentration to regions of low solute concentration.
		high water concentration to regions of low water concentration.
		low water concentration to regions of high water concentration.

What would happen if you placed a trout (a freshwater fish) into a saltwater tank at the aquarium and made some observations?

		The fish would lose water.
		The fish would take on water quickly.
		The fish would take on water initially, but could reverse the direction of Cl– ion movement to deal with excess water.
		The fish would lose water initially, but could reverse the direction of Cl– ion movement to deal with excess water.

Answer 1

1. Solutes from blood, Water, glucose , wastes.

Ultrafiterate in lumen of Bowmans capsule contains everything including both useful and waste products except blood cells and blood protiens.

2. Low solute concentration to high solute concentration.

High water concentration to the region of low water concentration.

Water moves from the region of higher water concentration or lower salt concentration to the region of lower water concentration or higher salt concentration.

3. The fish would loose water.

Saltwater is hypertonic for fresh water fish and water will move out of the body of fish into sea water.
