Which of the following is NOT a characteristic of the exoskeleton of an arthropod?
A. Always laden with calcium salts.
B. Chitinized with an outer layer of cuticle.

D. Composed of the tergum, sternum and pleura plates.
A human forearm, a horse's front leg, a bat's wing, and a porpoise's flipper have similar bone structure. What conclusions can we draw from the similarities in bone structure between these mammals?
a.
Such homologies do not exist in other areas of the vertebrate skeleton.
b.
Similarities among vertebrate forelimbs suggest they evolved from a common ancestor.
c.
Similarities among vertebrate forelimbs suggest they have evolved convergently.
d.
The anatomy of the vertebrate forelimb is not currently undergoing natural selection.
e.
Differences among vertebrate forelimbs suggest that they evolved independently.
You are studying the skeleton and bone morphology across reptiles. You find that in alligators a certain bone in the jaw has elongated whereas in a species of chameleon the bone has shortened in the jaw. In both species the bone still helps control feeding. Is this bone and skeletal morphology a homology?
a.
Yes, it is a homology
b.
No, it is not a homology
c.
Not enough information to tell
d.
The answer depends on the specific diet of each species

- Which of the following is not a reason we become shorter as we age? a.As a person ages, the intervertebral discs become thinner and the vertebrae will be stacked closer together, resulting in shorter stature. b.As a person ages, vertebral bodies lose bone mass (osteoporosis) resulting in smaller vertebrae that stack closer together. c.As a person ages, scoliosis may develop resulting in an abnormal spinal curvature and shorter stature. d.As a person ages, the ligaments connecting vertebrae together are weakened, resulting in a more pronounced kyphosis.
