Answer: c) the anticipated geographical spread of a disease based on past observances.
Explanation: Prevalence simply means the widespread of a thing or condition. In epidemiology, prevalence can be defined as the total number of people in a population that is affected by a medical condition or total number of cases of a disease in a population in a given period of time.
Expected prevalence of a disease is therefore the anticipated widespread of a disease or the anticipated total number of cases of a disease in a population based on past observed incidences.
Answer:
<em>The correct option is D) It does nothing to protect the atmosphere over Antarctica.</em>
Explanation:
On December 1, 1959, the Antarctic Treaty was signed in Washington. According to this treaty, Antarctica was to be used for peaceful purposes. This treaty regulates international relations with the Antarctica region. Freedom to different scientists for research in this area was given through this treaty.
However, the treaty did not discuss anything related to the protection of the atmosphere around Antarctica. Hence, option D can be considered to be a limitation of the Antarctic Treaty System.

Answer:
One of the factors for the development of pyelonephritis, in addition to E. coli, is urinary retention and reflux (option a).
Explanation:
Pyelonephritis is an infection of the upper urinary tract caused by bacteria in the urine, such as Escherichia coli.
Under normal conditions, urine in the urinary bladder is aseptic, that is, without bacteria. The presence of bacteria in the urine indicates a urinary infection.
Urinary retention is the limitation of the expulsion of urine from the bladder. This promotes:
- <em>An increase in the amount of bacteria present in the bladder.
</em>
- <em>The pressure generated by urine retention causes the bladder to generate a retrograde flow - reflow - towards the ureters, leading the bacteria to the kidneys.
</em>
The result of urinary retention and reflux - when bacteria are present - is an infection in the upper urinary tract, called pyelonephritis.
