The body fluids of an osmoconformer would be ________ with its ________ environment

• hyperosmotic; freshwater

• hyperosmotic; seawater

• isoosmotic; seawater

• hypoosmotic; seawater

The advantage of excreting nitrogenous wastes as urea rather than as ammonia is that________.

• urea can be removed as a semi-solid paste

• urea is less toxic than ammonia

• urea does not affect the osmotic gradient

• less nitrogen is removed from the body

Urine is carried from the kidneys to the bladder by two thin tubes called:

• Ureters
• Tubulars
• Capillaries
• Urinary Tract 

Identify Letter A

• Bowman's Capsule
• Afferent Arteriole
• Efferent Arteriole
• Glomerulus

The toxic, primary metabolic waste produced from the breakdown of nitrogenous (nitrogen-containing) molecules

• ammonia

• urea

• acetic acid

• hydrogen sulfide

Between two solutions with different osmolarities, the one with lesser solutes is said to be ___________.

• hyperosmotic

• hypoosmotic

• isoosmotic

To survive in a hyperosmotic environment, an osmoregulator must

• discharge excess water

• take in mineral salts and other solutes

• take in water to offset osmotic loss

Occurs as blood pressure forces fluid from the blood in the glomerulus into the lumen of Bowman's capsule

• Filtration

• Reabsorption

• Secretion

• Excretion

After filtration, the filtrate from the Bowman's capsule passes into what specific region in nephrons where tubular reabsorption into the interstitial fluid occurs?

• loops of Henle

• proximal convoluted tubule

• distal convoluted tubule

• renal corpuscle
