College Zoology

  1. proximate- "What stimulus elicits the behavior?"
  2. ultimate - "What physiological mechanisms mediate the response?"
  3. proximate - "How does the behavior aid in survival and reproduction?"
  4. ultimate - "How does the animal's experience during growth and development influence the response?"
College Zoology
Which of the following could be considered the most recent common ancestor of living tetrapods?
  1. a sturdy-finned, shallow-water lobe-fin whose appendages had skeletal supports similar to those of terrestrial vertebrates
  2. an armored gnathostome with two pairs of appendages
  3. an early ray-finned fish that developed bony skeletal supports in its paired fins
  4. a salamander that had legs supported by a bony skeleton but moved with the side-to-side bending typical of fish
College Zoology
Which of these statements about tetrapod blood vessels is correct?
  1. Arteries carry blood toward the atria of the heart.
  2. The pulmonary artery carries oxygen-rich blood from the lungs to the heart.
  3. Pulmonary veins carry oxygen-rich blood from the lungs to the heart.
  4. Arteries carry oxygenated blood; veins carry oxygen-poor blood.
College Zoology

College Zoology
Circulatory systems compensate for what?
  1. The problem of communication between the nervous system and respiratory system.
  2. The slow rate at which diffusion occurs over large distances.
  3. Temperature differences between the lungs and the active tissue.
  4. The need endothermic organisms have for maintaining an optimal body temperature.
College Zoology
Which of the following statements regarding the adult mammalian heart is correct?
  1. When the right atrium contracts, it forces blood into the left atrium.
  2. Blood in the right chambers of the heart cannot enter the left chambers without passing through the lungs.
  3. Blood is pumped from the heart via the atria.
  4. Blood arrives at the heart via the ventricles.
College Zoology
