An important point about the agent-host-environment model (the
epidemiologic triangle) of epidemiologic investigation is that:
A. the agent is not as important a factor in disease causality
as the host or the environment.
B. diseases are multi-causal.
C. it is necessary that the agent is linked to both the host and
the environment and that the agent is present in every case of the
disease.
D. in order to prove causality, which is a difficult task, the
researcher must prove...

In an organization there are four Hosts (i.e. Host A, Host B,
Host C and Host D) connected to a Router (i.e. Router0). Explain in
your own words (a) what happens when each of the four Hosts send a
broadcast (b) How many broadcast domains are on the Router0? (c) If
the Router (i.e. Router0) is replaced by a hub, how many broadcast
domains are on the hub? (d) If the Router (i.e. Router0) is
replaced by a switch, how...
EpidemiologyWhen dealing with infectious diseases, Epidemiologists have

b) What is an oxidizing agent?
c) What is reduction?
d)What is a reducing agent?

for?
3. a) How are electrons carried to the ETS/ETC
in cellular respiration? How in photosynthesis?
b) From where did these
electrons originally get their potential energy in cellular
respiration? Where in
photosynthesis?
4. Where is the ETC/S located in our cells?
Be specific!

1. Is the Epidemiological Triangle being used appropriately?
b. What reactions do you have to the approach to
"contact-tracing" being employed in this outbreak?
c. Do you have suggestions as to other tools that these public
health workers might use to trace their patients and convince them
to enter treatment?
d. Should more aggressive public-safety measures be employed,
perhaps even quarantine?
e. Consider COVID-19. Comment on how contact tracing is being
employed in our current health crisis.
