Rough-skinned newts from different regions of the Pacific Northwest vary greatly in their toxicity. Rough-skinned newts are preyed upon by garter snakes that have evolved resistance to the rough-skinned newts' toxin
Assume that newts and garter snakes form a coevolutionary mosaic. Try to predict what would happen if you fed a high-toxicity newt to a garter snake from an area with low-toxicity newts?
What will be an ideal response?
ANS:
The snake would be poisoned.

Use the following figure and information to answer the question(s) below
Fishes that have swim bladders can regulate their density and, thus, their buoyancy. There are two types of swim bladder: physostomous and physoclistous. The ancestral version is the physostomous version, in which the swim bladder is connected to the esophagus via a short tube (see the figure above). The fish fills this version by swimming to the surface, taking gulps of air, and directing them into the swim bladder. Air is removed from this version by "belching." The physoclistous version is more derived, and has lost its connection to the esophagus. Instead, gas enters and leaves the swim bladder via special circulatory mechanisms within the wall of the swim bladder. When a shark stops swimming, it _____. 1. sinks 2. quickly dies 3. oxygenates its blood less effectively A) 1 only B) 2 only C) 3 only D) 1 and 3 E) 1, 2, and 3

a. the production of human products by farm animals b. the development of new species of farm animals c. the increase of milk, egg, and wool production d. ultramodern methods of rearing more animals on less feed e. creation of transgenic animals that can produce more of their natural products
What can be said about the transfer of fluid from the glomerulus to Bowman's capsule?
A. It results from active transport. B. It transfers large molecules (e.g., proteins) as easily as small ones. C. It is very selective as to which small molecules are transferred. D. It usually includes the transfer of red blood cells to the nephron tubule. E. It is mainly a consequence of blood pressure force-filtering the fluid.
