A) Accept the original hypothesis
B) Reject the original hypothesis
C) Revise the original hypothesis
D) Design a new experiment based on a new or modified hypothesis.
2) Some researchers think pheromones are important tools in human
communication. Pheromones are chemical signals that one individual sends
to another. What research questions might be asked by anatomists, and
what questions might be asked by physiologists, to determine if
pheromones are important to humans?
,3) Iron atoms help our blood transport oxygen. Describe each level of
anatomical structural complexity for an iron atom in your blood, working
from the simplest level (atom) to the most complex (organism).
, 4) If someone speaks too loudly into a microphone, a public address
system will sometimes produce a loud whistle of amplified feedback. Explain
whether this is an example of negative or positive feedback, and explain how
the microphone, control box,and speaker of the system serve as the different
components of a feedback loop.
5) The discipline known as anatomy examines similarities and
differences across species.
6) The discipline that studies the functions of the nervous system,
including the way that impulses are conducted, is known as .
7) The discipline that associates changes in organ system function with
disease or injury is known as .
