1) identify what happens when the doctor hits your knee cap with the rubber hammer
during your annual physical.
a. the stimulus travels down the axon of your sensory neuron, through the dorsal root
ganglion, is transmitted through the dendrites of the sensory neuron to the interneuron.
from here it enters the cell body of the motor neuron and travels down the ventral root
axon of the motor neuron to stimulate the effector.
b. the stimulus travels down the axon of your sensory neuron, through the ventral root
ganglion, is transmitted through the dendrites of the sensory neuron to the interneuron.
from here it enters the cell body of the motor neuron and travels down the dorsal root
axon of the motor neuron to stimulate the effector.
c. the stimulus travels down the axon of your motor neuron, through the dorsal root
ganglion, is transmitted through the dendrites of the sensory neuron to the interneuron.
from here it enters the cell body of the motor neuron and travels down the ventral root
axon of the sensory neuron to stimulate the effector.
d. the stimulus travels down the axon of your sensory neuron, through the dorsal root
ganglion, is transmitted through the dendrites of the sensory neuron to the interneuron.
from here it enters the cell body of the motor neuron and travels down the ventral root
axon of the motor neuron to stimulate the receptor.
e. the stimulus travels down the dendrite of your sensory neuron, through the dorsal
root ganglion, is transmitted through the axons of the sensory neuron to the interneuron.
from here it enters the cell body of the motor neuron and travels down the ventral root
axon of the motor neuron to stimulate the effector.

b. more often when the bacteria are exposed to the drug.
c. at any time, even when the bacteria are not exposed to the drug.
d. only when the bacteria are exposed to radiation or other mutagens.
5) an insect destroying the ________ layer of tissues in a leaf would lead to a decrease
in the ability of gas exchange within the leaf.
a. spongy mesophyll
b. palisade mesophyll
c. xylem
d. epidermis

11) the correct sequence of increasing organizational complexity is
a. organ, tissue, cell, organ system, organism.

12) all of the following statements are true about squids except
a. squids are continuous feeders.
b. the squid’s tentacles seize its prey.
c. the mouth has jaws that bite off pieces of prey with the help of a toothy radula.
d. digestion occurs in the stomach and a cecum.
e. squids are molluscs.
13) descriptions of new species of insects are more likely to contain diagrams of the
shape of the male genitalia than head, wing, or leg parts. why?
a. this is where mutations usually express themselves in animals.
b. radiation damage to genes usually occurs in genitalia.
c. small changes in the genitalia cause reproductive isolation while a single species can
tolerate wider variation in head, wing, and leg morphology.
d. arthropods have hard exoskeletons so head, wing, and leg structures can’t vary as
much.
e. this is the convention or custom of entomology.
